Build and customize your very own open-source button grid controller. This DIY kit comes with delicious translucent button pads, driver boards, diffused white LEDS and a custom laser cut enclosure. The result is a sturdy and elegant but also super-hackable controller device for music, video…or something else???
Adafruit's Bluefruit HID controller is the easiest way to instantly add an HID keyboard or mouse interface to your project, even without a microcontroller. Did you know that you can also use it to convert a normal wired keyboard to supporting Bluetooth? In this project you'll learn exactly how to do it.. and in the process you'll bring an iconic piece of computing hardware into the modern age. Time to start digging around in your closet for that old IBM PC you haven't seen for a few years, because with Bluefruit and the Model M, "it just clicks".
Adafruit’s Bluefruit devices are hands-down the easiest way to get Arduino communicating over Bluetooth. Taking inspiration from the helical Guggenheim museum, this project coils a contiguous reel of NeoPixels around a dapper top hat to create a wearable scrolling message display you can control with your iOS/Android phone or tablet.
Representational state transfer (REST) is a software architecture that is widely used for web applications. In this project, we'll bring this architecture to Arduino so you can control an Arduino board via WiFi using a standard communication scheme. This way, you won't have to start from scratch at every new project and you'll be able to create complex wireless applications!
Pins are precious in the microcontroller world. How many times have you needed just one more pin? Sure, you could step up to a Mega and get a bunch more, but you really just need one or two. The DS2413 breakout board is the perfect solution. Each DS2413 breakout has 2 open drain GPIO pins and a 1-Wire interface. Just one of these boards will give you 2 pins for the price of one. But you can keep expanding from there. You can put as many of these boards as you want on the the 1-wire bus and still control all of them with just one Arduino pin. Each chip has a 48-bit unique address, which means you could have as many as 562 trillion GPIO pins! (In theory anyway)
Ever wanted to control your mobile robot remotely from your computer or your smartphone ? Now it is possible using Arduino and the CC3000 WiFi chip. In this guide you'll learn how to install the required components on a robot, and how to set the software environment so you can control the robot right from your browser
This tutorial demonstrates how to connect the Adafruit MAX31855 Thermocouple Amplifier breakout board to the Electric Imp using SPI, as well as how to set up a Xively developer account and a Twitter application. You will log and graph temperature data on Xively, and tweet it to your own Twitter account.
Have a lackluster datasheet for your sensor, but a demo app from the vendor that seems to calculate the value you need? If the app is written in .Net (Visual Basic or C#) -- and if it's Windows based, it probably is -- you might be able to decompile the app and find that magic formula you're looking for!
