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.

The HID Relay takes the form of a small adapter that has been built using an Arduino Pro Mini, a Bluetooth module, a USB host shield together with a few ...

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 ...
