The project presented here is a two-channel infrared remote ON/OFF switch that can be used to control home appliances, Lights, Fans, Water Pumps, Aquarium pumps, Ovens, Heaters, etc. This open-source project contains 2 x SSR (Solid State Relay), Arduino Nano, and TSOP1838 infrared...

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...

The circuit presented here is a LED dimmer with a soft-start function. The board can drive a LED up to 12W and the circuit can manage a load up to 1A continuous with 12Vsupply. The circuit is built using SG3525 PWM IC and the IRFR120 MOSFET, SG3525 generates the PWM, and IRFR120...
