Op-Amp Circuit Using Sensor and LED

A practical experiment was carried out using an operational amplifier (Op-Amp) to connect a sensor with an LED.

- The circuit was first assembled on a breadboard, including wires, resistors, the LED, and the Op-Amp chip.

- Before powering, the setup was checked to ensure correct connections.

- Once connected to a laboratory power supply, the sensor produced a weak signal that was amplified by the Op-Amp, strong enough to activate the LED.

- The experiment demonstrated the difference between the unpowered state and the powered state, highlighting the Op-Amp’s role in amplifying weak signals to drive other components.
