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 ...

If so, remember to connect the VCC pin to 5V of the Arduino board to enable the control input pins IN1 and IN2. Also note at this point that, if you want perfect galvanic-isolation, do not link ...

Finished RC-to-Arduino converter schematic So I added a third relay on one of the positive paths of one of the sets of wires.

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Plug another male-to-male connector into Pin 3 on the Arduino. This wire will connect to the positive port on the power relay connector (labeled with a “plus” symbol). Power your Arduino.

The programmable logic controller is fitted with 32 Inputs offering : 16 x digital 4-30V, 8 x analog 0-10V, 4 x analog 0-5V, 4 x analog 4-20mA) and 20 Outputs (8 x relay 250V/5A, 2 x open ...
