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 ...

We've got an exciting new book about the equally intriguing Arduino Uno R4. It is based on a 48-MHz, 32-bit Cortex-M4 processor with an ample amount of SRAM and flash memory. Plus, it features a ...
