The Arduino Mega interfaces with a relay module to control high-power devices or circuits with low-power signals. This enables applications such as home automation, motor control, and switching ...

We have the Arduino UNO board which acts as the main brain of this project. The RC522 RFID reader module is used to read the RFID cards and the 16x2 LCD is used to display the status information. The ...

So, to address these problems we will make an inexpensive voice-controlled home automation system using easy to find components such as Arduino Nano, HC-05 Bluetooth module and relay driver board. The ...

Zero - Arduino Try Out. From the circuit diagram of the module, it is clear that, apart from the module only a few external components are needed to build a relay-driver circuit. Yes, there is a ...

The Arduino Nano, when paired with a relay module, allows control of high-power devices, enabling applications like home automation, industrial control, and robotics in various electronic projects.
