Hello
Im using a set of leds to be powered up with a matching voltage source (regarding the numbers) when i directly connect them they light up normally.
I wanted to make a switch with a light dependant resistor which is a thermo coupled sensor.
When i branch the voltage source with the ldr branched in series at one end, the circuit works in a reciprocal way: when no light is on the leds shuts down, when there is a beam of light on the ldr the leds lights up. I want the vice versa of this phenomenon to be worked on this circuit.
Ow can i inverse this?
