Arduino Uno and 4 Relay Module are connected. If we have those connections, we need to set the Relay Module's pins as: module[1].setPinNumber(5).setPinMode(OUTPUT); 1st relay (IN1) is connected to the ...

Previously we have built 4-channel Relay Driver Module, but this time we are building this relay module as Arduino Shield, so that you just have to fix it over Arduino and it will be ready to use.

The receiver is built around Arduino Nano (Board2), Yoda module (YM2), Yoda adaptor(YA2), 2-channel relay module(RM1), and 5V DC power adaptor. Here, the Yoda module acts as an end-node module. 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 ...

Connections between Arduino and RFID are given in the table below. The positive pin of the buzzer is connected to digital pin 4 of Arduino, and the GND pin is connected to the ground pin of Arduino. A ...

This system is implemented using the NodeMCU ESP8266 Wi-Fi module, Arduino Uno, 4 channel relay module, temperature sensor (DHT 11), LDR and PIR sensor. The system can control home appliances both of ...
