The voltage divider can be paired with an operational amplifier to design the ideal light or dark sensor. First, connect the output of the LDR-resistor voltage divider to the non-inverting input of an ...

Step 1: Principle The LDR is a special type of resistor which allows a lower voltage to pass through it (high resistance) whenever its dark and higher voltages to pass (low resistance) whenever there ...
