Playing retro games is easy on a Raspberry Pi - and the pocket computer is pretty good at it too! All you need is a little help to connect buttons and a joystick up and you can custom design your own arcade console, desktop or stand-up machine, even just a simple controller box. It makes for a fun weekend project that will last all year. This Adafruit Arcade Bonnet is designed to make small emulator projects a little easier to build. Here's what you can look forward to!
For many microcontrollers, adding audio input is easy with one of our analog microphone breakouts. But as you get to bigger and better microcontrollers and microcomputers, you'll find that you don't always have an analog input, or maybe you want to avoid the noise that can seep in with an analog mic system. Once you get past 8-bit micros, you will often find an I2S peripheral, that can take digital audio data in! That's where this I2S Microphone Breakout comes in.
Pokemon GO has shown us that people can really go crazy over running around our cities bent on catching imaginary animals. It has also shown us that people are going crazy over chasing down said animals at all hours of the night and not always paying attention to what is going on around them. This is amplified when we are talking about children that are having a blast literally trying to catch them all. Build a safety light that's also a lovely way to show team spirit with this no-solder project!
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.
A physical disability can make it impossible to operate a touchscreen device such as an iPhone or iPad. Commercially available switch control devices can cost several hundred dollars but with the power of Adafruit Bluefruit BLE devices you can build an interface for a fraction of that cost. We show you how in this tutorial.
