Light Activated Motor Controller using IC 555
₹280.00
In StockA Light Activated Motor Controller using IC 555 is a simple electronic circuit that turns a motor ON or OFF based on the presence or absence of light. It uses a LDR (Light Dependent Resistor) as a light sensor and the 555 timer IC in a comparator mode, along with an LED to indicate the motor’s status.
Description
This project demonstrates how to control a DC motor automatically using light. It uses the 555 timer IC configured in monostable or comparator mode to detect changes in light intensity through an LDR (Light Dependent Resistor). When light falls on the LDR (or is removed, depending on the configuration), the circuit switches the motor ON or OFF. An LED indicator is used to show the motor’s operational state (ON/OFF).
This type of circuit is useful in automatic solar trackers, light-following robots, daylight-based ventilation systems, or smart irrigation where motors or fans need to be controlled based on ambient light.
Applications:
1.Solar-powered Systems
1.Turn on fans or pumps during daylight.
2.Light-following Robots
1.Control wheels or actuators based on light direction.
3.Automatic Window Ventilation
1.Open/close windows using motors when sunlight is detected.
4.Smart Irrigation
1.Start motors for water pumps when sunlight is available.
5.Educational Projects
1.Demonstrates sensor-based automation using the 555 timer.
