LED Blinking is a very common and almost first program for every embedded learner or beginner. In which we blink an LED with some delay. So today we are here with the same project, but here we will ...

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 ...

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 ...

In this DIY project we make a 3-Channel Arduino Relay Shield Circuit for relay based applications. We designed an isolated PCB for 3 relays. By using this Arduino Relay Shield, we can operate 3 AC ...

The concept of automation is getting popularity among people these days and many of them control their lighting, climate, etc remotely at their homes. Several microcontrollers or microprocessors can ...

In this IoT project, I have shown how to make an IoT-based Home Automation with Arduino IoT Cloud & Google Assistant using ESP32 to control 4 home appliances with voice commands. You can manually ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

CoreData Global, a Singapore-based research and development firm, has just introduced the RelayFi 4-channel relay board based on ESP32 and compatible with Tasmota open-source firmware, as well as ...

LilyGo T-Relay-8 is an ESP32 WiFi & BLE board equipped with eight 5V relays supporting up to 250V AC or 28V DC, as well as 16-pin GPIO header for expansion. The board offers a more compact solution ...
