Whenever we need to connect any AC Appliance in our embedded circuits, we use a Relay. So in this arduino relay control tutorial we will simply learn How to interface a Relay with Arduino. Here we are ...

An simple design that allows you to control relays via Ethernet. The project was dedicated to testing physical equipment on the production line. Communication is done via HTTP, so it is easy to ...

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 ...

Set the start pin and number of relays at the top of the sketch; 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, ...

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 ...

The article also describes how to program an MCU to accept infrared (IR) remote control signals for controlling the relays. Here, an ordinary TV remote control is used along with the 28-pin ATmega328P ...

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 ...

[Reza’s] methodical investigation of this remote controlled outlet let him patch in with an Arduino using a 433 MHz transmitter. This is a single-device unit, but the techniques used here sho… ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...
