Installation update

Building the circuit.

This is based on a teensy 3.0 microcontroller from Hobbytronics. I opted for this as it already had a powerful library for controllling WS2812 leds. It’s a very powerful controller and also benefits from having an in built real time click (handy if your building a clock!) and it can be programmed using the Arduino IDE.

Thanks to Paul at PJRC for  designing the controller and also creating libraries and sharing them with everyone else!! I doff my cap!

(from top to bottom ) The circuit consists of  –

3v battery (for the real time clock backup)
Teensy 3.0
3.3v to 5v converter chip
Data and power sockets.
