In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

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 ...

Flash this sketch to the Arduino; Connect to the Arduino's serial port with 9600 baud; Issue commands like 'r31' to turn relay 3 on, 'r00' to turn relay 0 off. You can send line breaks etc but they ...

Features: Hardware components: Arduino, relay module, jumper wires, and external power source Code: Arduino code for controlling the relay based on sensor input or a manual switch Applications: Home ...

Arduino Due and the Ethernet shield W5100 have the microcontroller, which has enough GPIO pins for the 16 channel relay , or 2x 8-channel relay. Since Due does not have everyone, the prepared source ...

In this project we control direction and speed of a 24v high current motor using Arduino and two relays.No power switches are needed for this circuit, just two push buttons and in Potentiometer to ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100. Hello, I'm going to share again with another project that helps many of you to solve ...
