150 LEDs, more problems.
Turns out the Pololu Voltage Booster couldn’t handle the current required and the over current protection was kicking in about twice a second, making the whole circuit flicker. And this was just testing 75 LEDs. I’ve put in an order for another DC-DC voltage booster that can apparently take 3A input. Hopefully this will be able to solve some problems, otherwise I could buy two more Pololus, but then efficiency would decrease a bit more.
Each matrix of 25 LEDs draws approximately 350mA at highest load, thus 6 panels requires an output of 350mA x 6 panels x 5 volts = 10.5W. This doesn’t include the dual Arduinos or the 4 sensors.
The 2000mAh battery is looking a bit short on juice.
