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 ...

It detects potential welded conditions and provides status updates through the serial monitor. Ideal for learning about relay management and timing functions, this project is built using Tinkercad for ...

Connect relays to digital output pins on whatever Arduino via appropriate isolation circuitry, starting at some pin (default 5), sequentially Set the start pin and number of relays at the top of the ...

ESP-01 is a tiny and useful piece of hardware. It has a 32-bit MCU, 2.4GHz 802.11 b/g/n WiFi, 1MB flash memory, and several other useful embedded features. Such ...

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 ...

Here using ATMEGA 4809 Arduino nano board and Capacitive Soil Moisture Sensor V2, I am trying to make an Automatic drip-irrigation system. Below is my code which is being used in the project. /* code ...
