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 ...

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 ...

As you can see in the file, when we hold the button, the motor will move clockwise due to the right relay, and then counterclockwise due to the left relay. To build the circuit, I used: Arduino board.

Automotive Motor Control using 4 channel relays for Arduino Uno Top ...

While there are a couple of open-source brushless drivers already available, [neuromancer2701] created his own brushless motor controller on an Arduino shield.

Fortunately, both the speed and direction of a DC motor can be controlled via an Arduino microcontroller. Let’s get into details. Direction control A circuit known as an H-bridge may be used to alter ...

To solve the problem without sourcing a new switch, [Jean-Noel] built his own Arduino based Dahlander switch. This consists of three relays that select the wiring configuration for each speed mode.

Arduino has recently announced two new expansions to their Arduino Pro Opta PLC series – the Arduino Pro Opta Ext D1608E and Arduino Pro Opta Ext D1608S, the main difference between the two is that ...
