Projects using this component
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
ESP32 Smart Lighting (PIR + LDR + Relay + OLED)
Turn your hallway, bathroom, or pantry into smart lighting with ESP32! Using a PIR motion sensor, LDR light sensor, and a relay module, we build the classic "light turns on when motion is detected in the dark" scenario — if the environment is already bright, motion does NOT trigger the light, saving energy during the day. The light stays on for 30 seconds; if motion continues, the timer resets and the light stays on longer. The SSD1306 OLED shows large-font status (ON / DAYTIME / WAITING), a cou
