This is a Dark Detecting LED light schematic I found here
Few Questions(As I'm new to electronics),
- Can I use this circuit with a 6v input ?
- When there is light on the LDR(Photo-resistor) curent will flow through R2 and PH1 (LDR) right ? So when there is light power will be wasted ? If so, how many Ma(Mili-amperes)?
- What to change if I want to use a 5v led(70ma @ 5v while input is 6v as stated in question No.1. It's 4Leds removed from a torchlight) ? (The resistor values)
Edit : I edited the questions after "Peter Bennett" answered.
