Tiny Touch Button

Finished PCB

With LEDs that require only one pin, you can do a lot with even just a 6-pin microcontroller!

A touch controlled light with 4xWS2812 RGB LEDs and ATtiny 10

This is a small hardware project which utilizes the light_WS2812 library and the TinyTouchLib to implement a touch-button controlled RGB-LED light. Only two output pins of the ATtiny 10 are used.

Atmel Studio project and Eagle files are included.

Make your own smart LED arrangement with the same integrated LED that is used in our NeoPixel strip and pixels. This tiny 5050 (5mm x 5mm) RGB LED is fairly easy to solder and is the most compact way possible to integrate multiple bright LEDs to a design. The driver chip is inside the LED and has ~18mA constant current drve so the color will be very consistent even if the voltage varies, and no external choke resistors are required making your design minimal. Power the whole thing with 5VDC and you’re ready to rock.
