How a Relay Module Works and Interfacing a Single Channel Relay Module with Arduino - Circuit Digest
By using an Arduino Uno and a single-channel relay module, you can control high-voltage or high-power devices, such as lights, motors, and appliances, from your computer or mobile device. In this blog ...
The relay module will need 5V from Arduino to power up and will get input from four different digital pins of the Arduino. Now let’s connect the relay module to your home appliance. Take the positive ...
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.

Fig. 3: Control panel on Android smartphone Relay module. A relay allows you to turn on or turn off a circuit using voltage and/or current much higher than what Arduino could handle. Relay provides ...
A 26.000MHz crystal is used in the ESP-01/ESP-01S module. In order to use the ESP-01 Wi-Fi relay module, a programmer/programming adapter is required to program the ESP-01 module (see below). Also it ...
I checked several Arduino projects and related libraries available online but was confused. Finally, I decided to do my first test with the help of a Windows 10 computer as the host. First, I ...
