# Motion Gift Box ## Overview https://youtu.be/XJiPfvexwAU In this project we’re making a motion activated gift box using [Adafruit Crickit](https://www.adafruit.com/product/3093) and [Circuit Playground Express](https://www.adafruit.com/product/3333). This holiday themed box moves around the floor as it makes creepy sounds and lights.   It uses a [PIR motion sensor](https://www.adafruit.com/product/189) to detect movement and a TT motor to spin a wheel. It also triggers lights and sounds making this an interactive gift box.   With Adafruits Crickit robotics platform, you can program with Circuit Python. ![micropython___circuitpython_hero-boardsB.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/654/medium640/micropython___circuitpython_hero-boardsB.jpg?1542054017) ![micropython___circuitpython_hero-trigger.gif](https://cdn-learn.adafruit.com/assets/assets/000/065/655/medium640thumb/micropython___circuitpython_hero-trigger.jpg?1542054336)   Use a cardbox and scraps to house the components and get crafty with the decorations.   It's easy to prototype with cardboard and paper crafts to make a unique gift box that you can customize! ![micropython___circuitpython_hero-loop.gif](https://cdn-learn.adafruit.com/assets/assets/000/065/656/medium640thumb/micropython___circuitpython_hero-loop.jpg?1542054429) ## Parts   You can find the list of all parts used to make this project linked below!   We used Circuit Python and programed our Gift Box to activate when the PIR sensor detects any moment. You can use the on-board sensors on the Circuit Playground Express to make it even more  interactive!   ## 3D Printed Parts   Although not require, our 3D printed mount is design to easily mount the Crickit to a battery pack.   ![micropython___circuitpython_parts.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/657/medium640/micropython___circuitpython_parts.jpg?1542054669) ![micropython___circuitpython_craft-parts.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/658/medium640/micropython___circuitpython_craft-parts.jpg?1542054759) ## Prerequisite Guides There's resources in these guides that go beyond what's covered in this tutorial.

They aren't true to scale, just meant to be used as reference. This diagrams was created using [Fritzing software](http://fritzing.org/download/). ## Adafruit Library for Fritzing Use our Fritzing parts library to create circuit diagrams for your projects. Download the library or just grab the individual parts. Files are hosted on our github repo linked below. [Adafruit Fritzing Parts](https://github.com/adafruit/Fritzing-Library/tree/master/parts) ![](https://cdn-learn.adafruit.com/assets/assets/000/065/660/medium800/micropython___circuitpython_circuit-diagram.jpg?1542055571) ## Connections ### Motor We used male to female jumper wires to easy connect and disconnect the Crickit from the motor. Connect each wire to the number 1 terminal on the Crickit's **Motor** terminal block. ### Battery The  3xAA battery case connects to the barrel port on the Crickit and is mounted to the bottom side of the printed lid or secured to the bottom the the Crickit with foam tape. ### Speaker Use two[ Alligator clip to Jumper wires](https://www.adafruit.com/product/3448) to connect the speaker terminals. Attached the alligator clips to the two tabs on the speaker and the jumper ends to the Crickit **Speaker** terminal blocks.   ## Passive Infrared Sensor (PIR)   Set the **Jumper** on the back of the PIR sensor from H to **L**.  The sensor connects to the 5v terminal on the NeoPixel side, while the GND and Signal connect to the 1 header on the **Signal I/O** side of the Cricket.     ![micropython___circuitpython_pir-jumper.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/703/medium640/micropython___circuitpython_pir-jumper.jpg?1542072168) # Motion Gift Box ## Code ![](https://cdn-learn.adafruit.com/assets/assets/000/065/740/medium800/micropython___circuitpython_code-banner.jpg?1542122124) ## CircuitPython The Adafruit Crickit and Cricuit Playground Express can run CircuitPython for programming fast and easy to read code.

[Adafruit CAD Parts](https://github.com/adafruit/Adafruit_CAD_Parts) # Motion Gift Box ## Assemble ## Trace Components   We can use any box that can accommodate all of the components. Standard Adabox size (9.5x2.5x6.5) will work perfectly!    Start by tracing the Crickit board in the back corner of the box, with the power barrel arranged as shown in the picture. Next we'll trace a TT motor with the wheel attached, slight off center on the opposite side of the box.    ## Wheel Cutout   Use a sharp hobby knife to cut away at the wheel section of the traced outline. Fit the motor and wheel over the cutout and make sure the wheel can freely spin without touching any of the sides. ![micropython___circuitpython_trace-componetns.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/662/medium640/micropython___circuitpython_trace-componetns.jpg?1542057582) ![micropython___circuitpython_trace-cutting-wheel.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/663/medium640/micropython___circuitpython_trace-cutting-wheel.jpg?1542058589) ![micropython___circuitpython_trace-cut-wheel.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/664/medium640/micropython___circuitpython_trace-cut-wheel.jpg?1542058617) ## Attach and Trace Bracket   Next we'll need to temporarily attach the bracket and trace it over our previous outline.   After tracing the outline, remove the bracket and outline the mounting holes.    Use M3 screws to create threads in the box. Create the hole so it only reaches the first layer of the box.    ![micropython___circuitpython_trace-bracket-attach.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/666/medium640/micropython___circuitpython_trace-bracket-attach.jpg?1542059016) ![micropython___circuitpython_trace-bracket.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/667/medium640/micropython___circuitpython_trace-bracket.jpg?1542059065) ![micropython___circuitpython_trace-bracket2.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/668/medium640/micropython___circuitpython_trace-bracket2.jpg?1542059110) ![micropython___circuitpython_traced-bracket.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/669/medium640/micropython___circuitpython_traced-bracket.jpg?1542059151) ## Bracket Standoff   To securely mount the motor and elevate the wheel, we'll need to create a standoff for the bracket.   We'll trace the cardboard pieces using the bracket as a reference and then glue the pieces to the box as shown.   Allow the glued parts to dry before mounting the bracket and motor. ![micropython___circuitpython_motor-bracket-cutout.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/670/medium640/micropython___circuitpython_motor-bracket-cutout.jpg?1542059239) ![micropython___circuitpython_bracket-standoff.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/671/medium640/micropython___circuitpython_bracket-standoff.jpg?1542059306) ![micropython___circuitpython_bracket-standoff-screws.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/672/medium640/micropython___circuitpython_bracket-standoff-screws.jpg?1542059485) ## Mount the TT Motor   Next we can move on to mounting the motor back on to the bracket.    Use the longer screws and nuts that are included with the bracket to secure the motor.   Once the nuts and screws a tightened, attach the wheel by inserting it at an angle. ![micropython___circuitpython_bracket-standoff-motor.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/673/medium640/micropython___circuitpython_bracket-standoff-motor.jpg?1542059563) ![micropython___circuitpython_bracket-standoff-motor-nut.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/674/medium640/micropython___circuitpython_bracket-standoff-motor-nut.jpg?1542059600) ![micropython___circuitpython_bracket-motor-attached.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/675/medium640/micropython___circuitpython_bracket-motor-attached.jpg?1542059632) ## Battery Mount   If you don't have access to a printer, we can simply use foam tape to attach the battery pack to the bottom of the Crickit.   A detail look at assembling the 3D printed Crickit Mount can be found here: [https://learn.adafruit.com/mount-for-crickit/3d-printing#step-6](https://learn.adafruit.com/mount-for-crickit/3d-printing#step-6)   Thread the wires through the frame and use the included M3 screws to mount the 3xAA battery case to the bottom of the mount.   We'll need additional M3x6mm screws to mount the Crickit to the 3D printed mount. ![micropython___circuitpython_battery-thread.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/676/medium640/micropython___circuitpython_battery-thread.jpg?1542059983) ![micropython___circuitpython_battery-screws.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/677/medium640/micropython___circuitpython_battery-screws.jpg?1542060024) ![micropython___circuitpython_battery-installed.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/678/medium640/micropython___circuitpython_battery-installed.jpg?1542060059) ![micropython___circuitpython_crickit-mount.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/679/medium640/micropython___circuitpython_crickit-mount.jpg?1542060154) ## Connect Components   Follow the circuit diagram to correctly wire each component to each terminal on the Crickit. ![micropython___circuitpython_components-wired.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/683/medium640/micropython___circuitpython_components-wired.jpg?1542061148) ## Infrared Sensor Mount   Now we can create the cut away to flush mount the PIR sensor to the side of the box.   Measure a circle with 55.8mm (2.2in) radius and create a template to trace on to the side of the box as shown in the picture.    ##   If using an Adabox, we can add the cutout over the "d" to align it to the center of the box.   Use a hobby knife to create the cutout and then press fit the PIR lens into place. ![micropython___circuitpython_pir-trace.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/684/medium640/micropython___circuitpython_pir-trace.jpg?1542062134) ![micropython___circuitpython_pir-trace-cut.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/685/medium640/micropython___circuitpython_pir-trace-cut.jpg?1542062240) ![micropython___circuitpython_pir-mounted.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/686/medium640/micropython___circuitpython_pir-mounted.jpg?1542062272) ## Ribs   We used scraps of cardboard to create boarders around the speaker and Crickit. This will help prevent the components from shifting around the box during movements.     Position the speaker in the front corner and trace an outline. Bend a strip of cardboard and glue the bottom to the box. We'll do the same for the boards around the Crickit.   Allow the glue to dry before press fitting the speaker and Crickit into place. ![micropython___circuitpython_speaker-rib.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/695/medium640/micropython___circuitpython_speaker-rib.jpg?1542066031) ![micropython___circuitpython_speaker-glue.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/696/medium640/micropython___circuitpython_speaker-glue.jpg?1542066674) ![micropython___circuitpython_speaker-gluedB.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/697/medium640/micropython___circuitpython_speaker-gluedB.jpg?1542066702) ## Box Flap   The flaps on the box will obstruct the PIR sensor, so we'll need to remove it. We can save the cut strip and reuse it to hide some of the components.    ## Wrapping paper   Next on to decorating our gift box! we'll measure our wrapping paper so the side are separate, allowing the box to full open.   ##   The rest of the box can have one continuous strip of wrapping paper.     ## Bow   For the last touch of detail, we added strips of ribbon a bow and a set of bells to jingle as the box moves!  ![micropython___circuitpython_box-lid-cut.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/698/medium640/micropython___circuitpython_box-lid-cut.jpg?1542066832) ![micropython___circuitpython_paper-cut.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/699/medium640/micropython___circuitpython_paper-cut.jpg?1542066969) ![micropython___circuitpython_paper-attach.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/700/medium640/micropython___circuitpython_paper-attach.jpg?1542067036) ![micropython___circuitpython_bow.jpg](https://cdn-learn.adafruit.com/assets/assets/000/065/702/medium640/micropython___circuitpython_bow.jpg?1542067144) ![](https://cdn-learn.adafruit.com/assets/assets/000/065/701/medium800thumb/micropython___circuitpython_hero-loop.jpg?1542067114) ## Guide Products ### Adafruit CRICKIT for Circuit Playground Express [Adafruit CRICKIT for Circuit Playground Express](https://www.adafruit.com/product/3093) Sometimes we wonder if robotics engineers ever watch movies.
