This is a DIY Arduino-based overcurrent relay project that emulates Inverse Definite Minimum Time (IDMT) protection using an Arduino Nano and ACS712 current sensor. Instead of traditional ...

A 10k ohm potentiometer is connected to an analog input. Turning it translates into values in the range [0-1023]. An attached SSR is connected to a water heater. By turning the SSR on and off, it is ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi with an ESP8266 ESP-01 module. With ...

Waveshare RP2350-Relay-6CH is a Raspberry Pi RP2350-based industrial 6-channel relay module with an isolated RS485 interface, 7 to 36V DC input via a terminal block, and support for Raspberry Pi Pico ...

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 ...

Make sure your Arduino board USB cable isn’t in any way loose. If the cable is a little loose at the ports, you might need to press it in more. USB cables that don’t allow serial communications will ...
