Tell us about yourself!
Hi there, was wondering if you could help. I have recently started out in electronics and have tried to make this solar engine. I've used all the components listed and have gone for a 2200uf Capacitor. To test out my circuit I have made it using solder-less breadboard. When I connect a battery (4X 1.5v in series) in place of the solar cell the LED lights up and stays lit but my motor does nothing. I have tested out the motor etc and it's fine. Am I having problems because the voltage of my batteries is too high, 6v total? Your help would be massively appreciated because it's really annoying that my engine won't work.Thanks.
