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 ...
LoRa-Project-with-ESP8266-Arduino-control-Relay 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 ...
Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.
Temperature Controlled Fan Circuit Diagram The complete circuit to build the temperature controlled fan using arduino and lm35 project is given below, we have used fritzing software for making most of ...
As Arduino Nano board (Board2) cannot provide sufficient current to drive a relay, a 5V DC power adaptor is used for powering the relay module/board (RM1). To use 5V DC power adaptor with the circuit, ...
Hello, I'm going to share again with another project that helps many of you to solve the issue of how to switch the relay remotely. I have done a bit of a specific project for 2 chats that are ...
It is very easy to build an “SMS-controlled relay” with the help of a cheap GSM modem module and a small microcontroller board. Here, I’m using the SIM800L and Arduino Nano V3 to develop a nifty ...
On the receiving end, I have used Arduino UNO. In the circuit, I have made a voltage divider using 4.7k and 10k resistors to drop down the 5volt logic level to 3.3volt logic level. I have used D4, D5, ...
