In this DIY project we make a 3-Channel Arduino Relay Shield Circuit for relay based applications.We designed an isolated PCB for 3 relays. By using this Arduino Relay Shield, we can operate 3 AC ...

It works in two different modes, Normally Open (NO) and Normally Closed (NC). in our project, we will use it in Normally Open mode which means when the relay is switched off the circuit will be broken ...

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 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 ...

In this Lora project, I have shown how to make the LoRa Arduino ESP8266 control relay using the RYLR896 LoRa module with real-time feedback. So after turning on and off the appliances the receiver ...

Interested in DIY a simple electronic impulse relay module? T. K. Hareendran designs an impulse relay circuit that mimics the functions of a conventional electromechanical impulse relay. This module ...

The circuit of the Arduino-based FM receiver, shown in Fig. 2, is built around Arduino UNO board (board1), TEA5767 radio receiver module (FM1), LM386 low-power amplifier (IC1), 16×2 LCD (LCD1) and ...

Working of LDR controlled LED using Arduino. As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k ... All we have to do is connect a relay module and set the parameter ...

This repository contains the Arduino code for a smart irrigation system using Arduino, moisture sensors, water level, a SIM800L module for SMS notifications, and relay modules for controlling valves ...
