Este proyecto implementa un sistema de control de encendido y apagado basado en la tecnología RFID utilizando un microcontrolador compatible con Arduino. El sistema verifica una llave RFID autorizada ...
Normal: Manual control of each relay All ON: Activate all relays All OFF: Deactivate all relays Alternating: Alternate between odd and even relays Sequential: Activate one relay at a time in sequence ...
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 ...
Abstract: This paper aims to design a digital overcurrent relay with a characteristic of a standard inverse that can comply to the IEC standard 60255. The overcurrent relay which is used to protect ...
