LED test

A project log for Flowers - Arduino Nano, CrazyCircuits, DFRobot

I got some components from CrazyCircuits, including these large LEDs and coin ceil holders with large holes for sewing. They also have conductive tapes and a testing board, making the circuit test very easy. 
I even used them to test a different project I'm working on that needed an external power supply.

I always test how thinks would look before construction. The LEDs should shine through the fabric. This is not the actual placement. I just needed to see how bright they show up.
