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 ...

LoRa-Project-with-ESP8266-Arduino-control-Relay In this Lora project, I have shown how to make the LoRa Arduino ESP8266 control relay using the RYLR896 LoRa module with real-time feedback. So after ...

An Arduino project for turning on/off a relay at a scheduled time. The project uses the Adafruit Feather and a real-time clock to ensure accuracy. This project is essentially a hand-made version of ...

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100.

After wiring up each outlet so it can be controlled independently, he set out designing a four port relay board. This was a pretty simple build – four 10 Amp relays and a few terminal blocks.

This article describes the construction of a simple Arduino RFID Access control DIY (Do It Yourself) Project using Arduino UNO and a RFID reader module (EM-18) to control an LED and a Relay. Circuit ...

To drive a relay from the Pi, one needs to cobble up a fairly simple circuit where the 3.3V GPIO pin turns on a transistor that drives the relay. This is such a common requirement that I figured ...
