Do I detect that you are in a hurry to get this working?
Ive spent every spare day for the past 6 weeks trying to get this working. I did have it working at one point but not enough power was getting through and the LED's were dim. It taken over my life, and my dining room. I need to get this working in the next few days.
I have a pong game code using 16 outputs from the arduino and code for 2 shift registers. Both codes work, i just need to get the 12v power to the board of leds. When i setup a simple 5v circuit and drive it from the arduino everything is fine.
I need to find the best way (and a way i understand as a noob to electronics) to get this lit up.
I sent you a PM, if you would consider allowing me to telephone you for some direct advice I would be extremly gratful.
Looks like another very long night going round in circles.
All the best,
