ir emitter circuit
Hi gang, I need your help again.
I'm using this simple ir emitter/detector circuit.
Normaly, the circuit output is 5 volts, when the detector detects the ir light, the voltage goes to 0 volts.
My question is: Is there a simple way to reverse this? In other words, I'd like the voltage to be normaly 0 volts and when the detector detects the ir light, the voltage goes to 5 volts.
Any help would be greatly appreciated.
Thanks
Bill
