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 ...

If you have a bare RGB LED instead of a module in a breakout board, you can make something akin to a module by attaching resistors on each of the color pins. The resistance value varies per ...

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 ...

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 ...

In this post we are reviewing the ESP-01 Wi-Fi Relay Module. ... Both boards have the blue LED but it is connected differently. ... or you can program the ESP-01 module with the help of the Arduino ...

An Arduino nano and relay module with 4 relays (see picture above) was used to simulate and replace the guitar 3-step switch. The project for Arduino is in PlatformIoClamp15. Node-red was used to ...

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 ...

Connecting the P10 matrix display module to Arduino is a very simple process, in our circuit, we configured pin 9 of the Arduino as Enable pin, Pin 6 as Pin A, Pin 7 as pin B, Pin 13 is the CLK, Pin 8 ...
