Smart Dual Coil Latching Relay Driver – Bistable Relay Module
This Smart Dual Coil latching Relay board can control the ON/OFF power of a device by applying a short voltage pulse to input 1 and input 2. This project is useful in low power applications since the coil is not powered all the time and only requires a short voltage pulse. The relay...

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...
