Lets take a simple example where we will be turning on an AC lamp by using a relay switch. In this relay circuit we use a push button to trigger a 5V relay, which in turn, complete the second circuit ...

This circuit is called a relay driver circuit, which is highlighted in the circuit diagram above. Learn more about relays here. Simulation of Flasher Circuit When the circuit is powered, the 555 Timer ...

In this assignment, I designed and analyzed two circuits: a BJT amplifier and a relay module. Problem 1: BJT Amplifier Design I determined the assigned BJT BC548 based on my student ID.

So, you can easily make this home automation project at home just by using an ESP32 and relay module. Or you can also use a custom-designed PCB for this project. This is the complete circuit diagram ...
