DC Motor Controller using Relay and MOSFET – Arduino Interface

DC Motor Controller using Relay and MOSFET – Arduino Interface

The project presented here is a low-cost solution to control high power brushed DC motor speed and direction. Traditional DC motor controllers are based on solid-state circuitry known as H-Bridge. Here we have made an H-bridge configuration using high current 2 x relays which can...

Analog Light Sensor + Light Sensitive Switch using OPT101

Analog Light Sensor + Light Sensitive Switch using OPT101

You may have seen many light-sensitive switch circuits based on an LDR sensor. Usually, the sensitivity of the LDR based light sensor is poor. We wanted a very sensitive light switch hence we decided to make a circuit based on a light sensor rather than LDR. After a little research on...
