Use a small screwdriver to screw in the leads into the terminal blocks. - Plug the ** servo**  into `input 1` on the  **servo section**  on CRICKIT. Orient the leads such that the yellow wire is on the outside edge of CRICKIT. - Attach an alligator clip to capacitive touch `input A3` on the CPX (Circuit Playground Express) - For power, for now, use a [5V 2A (2000mA) switching power supply](https://www.adafruit.com/product/276) plugged into the `5V DC jack`. - Screw in NeoPixel strip to` NeoPixel terminal block` of CRICKIT after prepping the wires via directions below. For more info on using NeoPixels with CRICKIT, check out this guide: [Make it Glow with CRICKIT](https://learn.adafruit.com/make-it-glow-with-crickit/overview). ![makecode_IMG_6304.jpg](https://cdn-learn.adafruit.com/assets/assets/000/066/260/medium640/makecode_IMG_6304.jpg?1542693196) In order to attach the NeoPixel strip to CRICKIT, we will need to prep the Data In end of the strip. ## Prepping the NeoPixel strip for CRICKIT: - Take the end of the NeoPixel strip with the **data line arrow pointing inward toward the strip**. - With wire cutters, cut the end of the **white wire.** - Strip off 1 cm of wire cover from white wire as well as ground (black) and power (red) wires. ![makecode_IMG_6090.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/410/medium640/makecode_IMG_6090.jpg?1541721114) ![makecode_IMG_6091.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/411/medium640/makecode_IMG_6091.jpg?1541721123) ![makecode_IMG_6092.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/412/medium640/makecode_IMG_6092.jpg?1541721134) ![makecode_IMG_6094.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/413/medium640/makecode_IMG_6094.jpg?1541721140) # Adding Louder Sound You may like the song the little crickit bot plays but want it to be a little louder. By default it only plays from the little buzzer on the Circuit Playground. By adding a 8 ohm speaker to the Crickit speaker output you'll get a blast of audio! ### Mini Metal Speaker w/ Wires - 8 ohm 0.5W [Mini Metal Speaker w/ Wires - 8 ohm 0.5W](https://www.adafruit.com/product/1890) Listen up! This tiny 1" diameter speaker cone is the perfect addition to any small audio project where you need an 8 Ω impedance and will be using 0.5W or less of power. We particularly like this cone as it's very simple and its metal body is extremely lightweight.

We'll be using programming called MakeCode to do that. # Crickit Powered Maker Ice Cream Truck! ## Programing with MakeCode ## What is MakeCode? MakeCode is a web-based code editor for physical computing made by Microsoft. What does that mean for you? It means you can program your Circuit Playground Express to do almost anything you can dream up right from a website! You can code with blocks similar to the language Scratch, or you can do more advanced coding with Javascript. We'll be sticking to the block-based programming for this project. More on MakeCode for Adafruit boards [here](https://learn.adafruit.com/makecode). ## Install the MakeCode CRICKIT Extension Before we start programming, let's make sure you have the CRICKIT extension installed in MakeCode. Detailed instructions on how to do that can be [found in this guide](https://learn.adafruit.com/adafruit-crickit-creative-robotic-interactive-construction-kit?view=all#adding-crickit-extension "MakeCode Crickit Extension"). ## Create a New Project with MakeCode Head over to [https://makecode.adafruit.com/](https://makecode.adafruit.com/) and create a new project. Click the button below to access the code for this project. [Open the code for the project in MakeCode here.](https://makecode.com/_Rmb52F8RsX4F) ![](https://cdn-learn.adafruit.com/assets/assets/000/065/776/medium800/makecode_Screen_Shot_2018-11-13_at_6.02.56_PM.png?1542150181) ## What's going on the code above? - On `start`, we initialize the NeoPixel strip. - In a `forever loop`, we set the `brightness` of the NeoPixels, set the CPX NeoPixels to a specific color, call the comet animation for the NeoPixel strip for `3 seconds`, set the `volume` of the CPX speaker, then play the "Do Your Ears Hang Low" tune by calling the `song functions`. As it's a forever loop, this code block loops forever regardless of other events that happen in the code! ![makecode_Screen_Shot_2018-11-13_at_6.13.14_PM.png](https://cdn-learn.adafruit.com/assets/assets/000/066/250/medium640/makecode_Screen_Shot_2018-11-13_at_6.13.14_PM.png?1542690815) - The "Do Your Ears Hang Low" tune can be separated into 3 parts. The song starts with part 1, then goes to part 2, then back to part 1 then ends with part 3 before repeating again (and again and again...). Creating functions for these song parts then "calling" the functions later allows us to have much cleaner looking and more organized code. It also allows us to reduce the amount of code needed for the project making the program more efficient! ![makecode_Screen_Shot_2018-11-13_at_6.12.31_PM.png](https://cdn-learn.adafruit.com/assets/assets/000/066/251/medium640/makecode_Screen_Shot_2018-11-13_at_6.12.31_PM.png?1542690876) - When capacitive touch `input A3` on the CPX is touched, we want to call the `wave function` (which makes Adabot wave with ice cream in hand), then move the DC motors each at `65% speed` for `8 seconds`, stop the motors, then call the `wave function` again. ![makecode_Screen_Shot_2018-11-13_at_6.12.48_PM.png](https://cdn-learn.adafruit.com/assets/assets/000/066/252/medium640/makecode_Screen_Shot_2018-11-13_at_6.12.48_PM.png?1542690928) - The wave function starts the `servo at 0 degrees`, then moves to `150 degrees`then back to `0`, repeating `5` times in total. ![makecode_Screen_Shot_2018-11-13_at_6.12.38_PM.png](https://cdn-learn.adafruit.com/assets/assets/000/066/253/medium640/makecode_Screen_Shot_2018-11-13_at_6.12.38_PM.png?1542690968) ## Uploading the Code Now that we have the code for the project, we need to upload it to the CPX. Let's name our file and download it. - Choose a name at the bottom of the page. - Then click the pink  **Download**  button. Follow the directions and connect your CPX to your computer via the usb cable. Click the CPX Reset button once to go into programming mode (all NeoPixels will turn green). In some cases, you may need to press the reset button twice to get into programming mode. Next, look for the file in your downloads folder and drag it onto your  **CPLAYBOOT**  drive that should have showed up in your file manager/finder when you plugged in your board and entered programming mode. You should now see the  **CPLAYBOOT**  drive disappear. ## Power up CRICKIT Connect CRICKIT to power with the 5V DC power cable The code should now be running so try it out! - When the board is powered up, the NeoPixels on both the CPX and CRICKIT should come on and "Do Your Ears Hang Low" should start playing. - When the tin foil is touched, the servo should move back and forth five times, then the motors should both turn for eight seconds. Lastly, the servo will move back and forth five more times. If you are having issues getting things to work check out this extended guide [here](https://learn.adafruit.com/makecode/downloading-and-flashing). ![](https://cdn-learn.adafruit.com/assets/assets/000/065/786/medium800/makecode_IMG_6191.jpg?1542152177) # Crickit Powered Maker Ice Cream Truck! ## Adding Portable Power The DC motors are **power hungry**. This requires a beefy power supply if we want to make this truck portable. [This guide](https://learn.adafruit.com/crickit-snake-bot/a-bigger-better-power-supply) does a great job explaining this issue in more detail. If this is your first time soldering check out this guide: [Adafruit Guide To Excellent Soldering Solder at peak performance!](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools "Adafruit Guide To Excellent Soldering Solder at peak performance!") If you wanna skip the soldering, you can use a [portable USB pack](https://www.adafruit.com/product/1565) and hook it up to CRICKIT with [this cable](https://www.adafruit.com/product/2697). ![](https://cdn-learn.adafruit.com/assets/assets/000/065/799/medium800/makecode_IMG_6195.jpg?1542152858 *picture is excluding switch) - Remove USB extension from PowerBoost board. Removes easily by pushing out prongs. - Cut ends of black and red bread board wires, and remove 1-2 cm of wire wrap from end. - Solder red wire to `power` and black to `ground`. - Solder on switch to PowerBoost over `Vs, EN and GND`. Orientation doesn't matter. - Screw in power and ground leads to terminal block on DC jack. - Plug in JST connector from battery to PowerBoost. - Plug in DC jack to CRICKIT. ![makecode_IMG_6196.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/801/medium640/makecode_IMG_6196.jpg?1542153306) ![makecode_IMG_6197.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/802/medium640/makecode_IMG_6197.jpg?1542153312) ![makecode_IMG_6199.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/803/medium640/makecode_IMG_6199.jpg?1542153321) ![makecode_IMG_6203.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/806/medium640/makecode_IMG_6203.jpg?1542153392) ![makecode_IMG_6200.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/808/medium640/makecode_IMG_6200.jpg?1542153445) ![makecode_IMG_6205.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/809/medium640/makecode_IMG_6205.jpg?1542153452) Turn on the soldered switch and we have some hefty portable power! ![](https://cdn-learn.adafruit.com/assets/assets/000/065/800/medium800/makecode_IMG_6202.jpg?1542153283) # Crickit Powered Maker Ice Cream Truck! ## Constructing the Truck Download and print out The PDF of various truck parts and cut outs by clicking the button below. [ice_cream_truck_print_out.pdf](https://cdn-learn.adafruit.com/assets/assets/000/065/408/original/ice_cream_truck_print_out.pdf?1541720912) Warning: ## Cut the Outer Truck Parts - Prepare enough medium to large width sized cardboard to fit all outer truck parts onto (pages 1 - 5 in pdf). Thicker cardboard makes for a sturdier truck! - On the print outs, the **dotted lines are meant for cutting ** and the **bold lines are meant for folding.** - Cut out the parts from the print outs **pages 1 - 5\*** - Glue to cardboard. - Cut out parts with hobby knife. \* Cutting the parts out before glueing is optional but helps save room and makes for a cleaner looking result. To save time you can glue the entire print out sheets to the cardboard and cut them out. ![makecode_IMG_6108.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/335/medium640/makecode_IMG_6108.jpg?1541699263) ![makecode_IMG_6113.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/336/medium640/makecode_IMG_6113.jpg?1541699272) ![makecode_IMG_6115.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/337/medium640/makecode_IMG_6115.jpg?1541699282) ![makecode_IMG_6116.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/338/medium640/makecode_IMG_6116.jpg?1541699293) ![makecode_IMG_6117.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/339/medium640/makecode_IMG_6117.jpg?1541699304) ![makecode_IMG_6121.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/340/medium640/makecode_IMG_6121.jpg?1541699308) ## Score and Fold Parts - Over  **bold lines** on each side of the truck, make light incision with hobby knife. - Next take a pencil or pen and score until parts fold. These are now the back doors of the truck. -  For the truck front, make a light incision on the bold line above the grills and headlights. - Score and fold. - For upper fold, turn over front piece, measure about 5mm below windows, draw a line across the back. - Lightly go over with hobby knife then score and fold. **Score multiple times before folding this part** as proximity to windows risks improper folding. ![makecode_IMG_6123.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/343/medium640/makecode_IMG_6123.jpg?1541700268) ![makecode_IMG_6124.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/344/medium640/makecode_IMG_6124.jpg?1541700295) ![makecode_IMG_6125.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/345/medium640/makecode_IMG_6125.jpg?1541700307) ![makecode_IMG_6127.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/347/medium640/makecode_IMG_6127.jpg?1541700335) ![makecode_IMG_6128.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/348/medium640/makecode_IMG_6128.jpg?1541700361) ![makecode_IMG_6129.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/349/medium640/makecode_IMG_6129.jpg?1541700379) ![makecode_IMG_6130.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/350/medium640/makecode_IMG_6130.jpg?1541700384) ![makecode_IMG_6132.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/351/medium640/makecode_IMG_6132.jpg?1541700389) ## Glueing pieces together: - Put hot glue onto the front of the left side of the truck. - Place front of truck piece onto left side piece, aligning scored folds with the contours of the side piece. - Repeat with other side. - Glue on truck top. - Feel free to reenforce with glue wherever connections feel weak. \*We will leave the bottom of the truck alone for now as we will assemble the character cut outs, electronics and wheels on this piece before connecting to the rest of the truck. ![makecode_IMG_6134.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/357/medium640/makecode_IMG_6134.jpg?1541700930) ![makecode_IMG_6135.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/354/medium640/makecode_IMG_6135.jpg?1541700855) ![makecode_IMG_6136.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/355/medium640/makecode_IMG_6136.jpg?1541700868) ![makecode_IMG_6133.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/356/medium640/makecode_IMG_6133.jpg?1541700921) # Crickit Powered Maker Ice Cream Truck! ## Adding Adabot, Blinka and Ice Cream! ## Cut Out Characters and Props - From page 6 of the PDF print out, cut out Adabot and Blinka\* - Glue characters down onto a thin width-sized cardboard. - Use a pencil to draw a small rectangle sized slightly less than Blinka's length.
