Lighting 220V Bulb with Remote Control

Project that turns 220V light bulb on and off via relay with power and mute buttons of IR remote control. Combines infrared control with high voltage switching.

Smart Irrigation Station

Autonomous plant irrigation system that works 24/7 with two 18650 batteries and LM2596 regulator without tiring Arduino. It automatically manages the water motor by continuously measuring soil moistur

Lighting 220V Bulb with Push Button

Project that controls a 220V light bulb with a push button using a relay module. Teaches the basics of high voltage switching with relay.

Lighting 220V Bulb with Button (On-Off)

A project that turns a 220V light bulb on and off (toggle) at each button press with a relay module. Teaches permanent switching logic with relay and state variable.

ESP 32 Smart Plant Watering System

In this project, an automatic plant watering system was developed using an ESP32 and a soil moisture sensor. The sensor continuously measures the soil’s moisture level. When the moisture level drops below a specified threshold, the ESP32 activates the relay to turn on the water pump and water the plant. When the soil is sufficiently moist, the pump automatically stops. Thanks to this project, plants can be watered regularly, and water can be conserved. _______________________________ Connections
