One day we want to make light jewelries - not like a traditional jumping LEDs with battery but more interesting - with reaction on enviroment changes, on light, temperature or heartbeat.
We check many DIY boards but not found any thats will be simple, compact and tiny - its all have some extra things - big batteries, powerful MCUs, needless connectors. That's why we make it.
Our device has:
Size - 30 x 30 mm.
There are two variants of the board:
There are another three variants about sensors:
You can programm it with Arduino IDE, using Arduino Nano for uploading (Arduino ISP).
You must choose Attiny 85 profile on 8 MHz (16 MHz is too mutch for 3V).
For RGB LEDs we using patched FAB_LAB library.
Code examples for photoresistor variant can be found on GitHub
Go to the section 'Electronic jewelries', to see examples of using our devices.
