We love some good LED blinking as much as the next person but after years of LED-soldering we need something cooler to get us excited. Sure there are RGB LEDs and those are fun too but what comes after that? Well, we have the answer: LED Strips! These are flexible circuit boards with full color LEDs soldered on. They take a lot of LED-wiring-drudgery out of decorating a room, car, bicycle, costume, etc. Here is a quick tutorial on how to get an LED strip working with an Arduino.
Once you have mastered the basic blinking leds, simple sensors and buzzing motors, it’s time to move on to bigger and better projects. That usually involves combining bits and pieces of simpler sketches and trying to make them work together. The first thing you will discover is that some of those sketches that ran perfectly by themselves, just don’t play well with others. There are ways to effectively juggle multiple tasks on an Arduino. This series of guides will show you how.
If walls could talk. If fridges could email. If toasters could tweet. If garbage cans could blog. If sinks could post stories. If stoves could code. The Internet of Things can be in all the things. Adafruit, Digikey, and Nimbus the Friendly Cloud Entity are here to help you learn how to connect everything you need and nothing you don't.
Interpretting datasheets is fraught with peril in the best of circumstances. Even chips from the same vendor can use varying terminology and units, often in an attempt to hide short-comings in individual devices. Trying to compare chips across vendors adds another layer of complication. We'll help you decipher the key terms around gyroscopes in this learning guide.
With some development boards, low power usage is an afterthought. Especially when price and usability is the main selling point. So what should you do when its time to turn around and make that project of yours run on a battery or solar? Sure you could try to hot-air that regulator off, or you could jerry-rig a relay. Or, use a 555? Ugh, the options aren't that great.
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!
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.
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.
The NeoPix Arcade Kit is a 1D arcade game system to encourage young programmers to code. The NeoPix Arcade Kit comes with a preprogrammed Circuit Playground that includes our 1D Pong Game to immediately start exploring basic game programming concepts on the Circuit Playground. The Circuit Playground Board has a host of sensors to create a variety of handheld electronic gaming projects.
