Hello,
I currently have a 10x3 LED circuit that works great. The LED's are always on and they run off of a 12VDC power supply. Each 3-LED branch recieves 20mA (I'm using 20mA LED Drivers). However, now I want them all to blink simultaneously. I can use my UNO to program the LED's to blink at set Duty Cycle, but the ATMega328 obviously cannot meet the power requirements of my array (12V,200mA).
Is it possible to upload the sketch to an appropriate shift register and drop it into my circuit?
Thanks for reading.
