Update:
I have found that running my lights under 50% intensity has been fine on my schedule. When I try and turn the lights up to max (especially on the white channel) something messes up and the lights go dim until I reboot the Robo Tank and power cycle the lights.
I suspect it might be an overcurrent issue so I have some testing to do. The transistors are rated at 5A, and my lights are powered by a 3A and a 2A power brick, each of which powers two channels (a blue and a white light channel) so I should be within operating range of the transistor. I'll have to check temperatures to see if the transistors are overheating.
Rob, what are the current and resistance limitations of the PWM channels on the robo tank board? I'm wondering if it is possible that I am overloading something in the circuitry there instead.
