experiments with 741 operational amplifier


Posted on Feb 5, 2014

This versatile 741 operational amplifier module can be used for making a dark detector using an LDR, a photo transistor and a photo diode. The amplifier has been configured in inverting mode. It compares the change in voltage at pin 2 with the reference voltage at pin 3 and gives output at pin 6 accordingly. A general calculation and
