Synergy is a free and open source software that allows you to share a mouse and keyboard between multiple computers. It is a great way to remotely control a Raspberry Pi that is already connected to a display. However, there are some difficulties regarding the installation of Synergy, which this guide will help overcome.
Light painting is an artistic medium combining light, motion and long-exposure photography. For as long as a camera’s shutter is open, a single point of light in motion will create a continuous streak in the final photograph. Digital technology takes light painting to the next level…dozens of point lights, with color and brightness individually under computer control, weave a swath of awesome across the completed frame. Adafruit’s NeoPixel strips, combined with the Arduino microcontroller and a supporting cast of parts, make highly refined digital light painting achievable!
Trellis is an open source backlight keypad driver system. It is easy to use, works with any 3mm LEDs and eight tiles can be tiled together on a shared I2C bus. Each Trellis PCB has 4x4 pads and 4x4 matching spots for 3mm LEDs. The circuitry on-board handles the background key-presses and LED lighting for the 4x4 tile. However, it does not have any microcontroller or other 'brains' - an Arduino (or similar microcontroller) is required to control the Trellis to read the keypress data and let it know when to light up LEDs as desired.
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.
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
We are excited to add another product to our growing Adafruit Bluefruit line, this time its the Bluefruit EZ-Link: the best Bluetooth Serial Link device ever made. Like you, we have purchased all sorts of Bluetooth serial link modules, with high expectations - we just wanted something that worked! But nothing ever did exactly what we wanted: there was always some configuration modes to wade through, and using one of those other modules to reprogram an Arduino is impossible. So we did what we always do, we went in and engineered something better. Something that works!
Replay those old school retro videos games and cut the cord to build your own wireless SNES controller powered the EZ-Key Bluefruit. Our SNES controller has 12 buttons, which is perfect for the EZ-Key. A slide switch at the bottom easily let's you power it on. The top includes a USB charger so you can recharge the lithium battery.
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!
