Arduino is a great starting point for electronics, and with a motor shield it can also be a nice tidy platform for robotics and mechatronics. Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects. Build the kit, and learn how to use it with these detailed instructions.
This guide will use the capacitive touch pads on the Circuit Playground Express and the capacitive properties of fruit to create a full scale tone piano. We will write the code using CircuitPython to use each of the touch pads to light up the Neopixels in a different color and play a different tone through the onboard speaker.
The original Adafruit Motorshield kit is one of our most beloved kits, which is why we decided to make something even better. We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project! We kept the ability to drive up to 4 DC motors or 2 stepper motors, but added many improvements:
Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (16-bit 262,000 different shades)! 240x320 pixels with individual pixel control, this has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. Learn how to use this LCD with an Arduino.
This is a quick tutorial for our 84x48 pixel monochrome LCD display. These displays are small, only about 1.5" diameter, but very readable due and comes with a backlight. This display is made of 84x48 individual pixels, so you can use it for graphics, text or bitmaps. These displays are inexpensive, easy to use, require only a few digital I/O pins and are fairly low power as well.
Mu is an amazing editor that works with CircuitPython and compatible boards. You can connect to the serial REPL right inside the editor. It also includes a plotter the works with your code to give you a live visual graph of your data! This guide will show you different ways to use the plotter with different sensors. It's time to plot!
Portage for your projects! Lady Ada's Bento Box is a crush-proof, drop-proof & water-proof prototyping kit that combines the ultra-rugged Otterbox 3000 with a storage tin and half-size (400-point) breadboard. In the middle is a spot for attaching an Arduino UNO (or any other PCB that has the same shape and mounting holes). There's plenty of clearance for wires (even ones with plastic bits on the end such as our premium jumper wires or wire bundles) and parts on the breadboard, and the box is so sturdy you never have to worry about any delicate parts inside getting damaged. Toss it in your backpack, suitcase, duffel bag and you can be sure to work on it when you get to school, work or home.
This is Lesson 10 in the Learn Arduino Adafruit series. In this lesson, you will learn how to make sounds with your Arduino. First, you will make the Arduino play a 'musical' scale and then combine this with a photocell, to make a Theramin-like instrument that changes the pitch played as you wave your hand over the photocell.
A collection of mini-tutorials on doing stuff with the Chumby Hacker Board. The CHB is a cool single board Linux computer that has much of the same hardware as the famous Chumby One. It's great for people who are experienced with Linux and want to have the power of a microcomputer with audio and video output while at the same time getting all the peripherals of a microcontroller such as analog-to-digital conversion, PWM outputs, sensors, bit twiddling, and broken-out GPIOs!
Bring a little bit of Times Square into your home with our RGB LED matrix panels. These panels are normally used to make video walls — here in New York we see them on the sides of buses and on bus stops — to display animations or short video clips. We thought they looked really cool so we picked up a few boxes from the factory. Learn how to get these LED matrices up and running with an Arduino.
Ladyada and pt had an old NeXT keyboard with a strong desire to get it running on a modern computer. These keyboards are durable, super clicky, and very satisfying to use! We spent a few days and with a little research we got it working perfectly using an Arduino Micro as the go between. Now this lovely black deck works like any other USB keyboard. Sure it weighs more than our Macbook, but its worth it!
