Hm. Near as I can tell the lights need 19.5V. Are there devices/circuits that can up the PWM voltage out of the robo-tank from 5V to 19.5V?
I searched a bit (not really knowing what I'm looking for) and came across this: https://www.digikey.com/product-detail/e...ND/6137684 the price is high considering I'd want 16 (1 for each PWM channel on the robo-tank) AND I noticed the Current - Output (Max) is 42mA. GroBeams are 12W each. P=VI, 12W=19V*I (that component is 19V output and not 19.5V), 12/19=0.63157894736842105263157894736842 or about 632mA...well over the max 42mA which that component supports.
