Introduction: Basic Comparator 741 Ic
The most basic comparator circuit
Step 1: Gathering Parts
What we need is -
2-any 741 ic
3-a simple sensor (eg -compound mic,LDR)
4-LED or any other output device
7-9v power supply
Step 2: Pin Out for a 741 IC
Ignore pins 1,8 and 5.
3-non inverting input
Step 3: Connections
1-place the IC on the bread board
2-take a wire and connect pin 7 to a positive rail,(Where the positive of your power supply is)
3-take a wire and connect pin 4 to a negative rail,(Where the negative of your power supply is)
4-take a wire and connect pin 6 to an LED to the negative rail
5-place the sensor and POT on the board
6-connect both their positive pins to the positive rail
7-connect the sensors other pin to pin 2 and the POT's to pin 3
8-Power it up
9-Adjust the POT accordingly
We have a be nice policy.
Please be positive and constructive.
