how to use LDR as a relay for RC car to increase voltage to motor Answered
I would like to know more about how LDR's work, its quite difficult to source 3 volt relays in South Africa, so I had an Epiphany, why not use 2x LDR 1x for Forward and 1x for Reverse on an RC car, I don't know much about how responsive the solution is, how many seconds or milliseconds delay there is? Does it work like a switch? would it be a viable option on an RC car?
I'm sure this could apply to little 3 volt RC cars upwards, I know brushless is the way to go, however this would indeed be a great learning experience.
