LighTouch was an idea I had as I was just diving into Arduino. Like anyone getting started, I bought an Uno and three random shields just to play with (music shield, bluetooth, and ultrasonic range finder). To that end, I got each of them up and running in record time and got bored. So what was the next logical step? Right… figure out how many of these shields can I use at the same time. In this case, a music shield and ultrasonic range finder made the cut.
The idea is pretty simple; an mp3 player that you never have to touch. Simply hold your hand over the device to adjust volume, pause, and move to the next track. All the commands basically key on the distance of your hand from the sensor.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
