Pushbuttons or switches connect two points in a circuit when you press them. Arduino or Genuino Board Momentary button or Switch 10K ohm resistor hookup wires
Using a CdS by Lewis In the above circuit (Fig. A) R1 is a CdS photocell in series with a 1000ohm PChannel Power MOSFET Switch.
This project illustrates the use of motion and light sensors with Arduino, use one as a switch on the LDR part of the circuit to a photocell is the easiest.
