hello : )
i wonder if you can help ? is there a simple circuit ( other than perhaps a relay) that when you send 5v into the circuit an LED is turned off and when the 5v is reduced to 0v the LED instead lights up : )
i have a fair few LEDs to turn off and on individually like this so am hoping to keep the current consumption as low as possible.
thanks for any help : )
