V3.0 - Using NodeMCU ESP8266 for controlling switches (Relay). Uses RTC (Real Time Clock - DS3231) and NTP (Network Time Protocol) for maintaining time. OLED Display (128x64) for instant updates. A webserver for Manual Controls. Vast application including Aquariums and IOT related.

It is a simple flutter app with bluetooth connectivity to send data to HC-05 Bluetooth module. I used shared preferences for small data storage such as time.

No-code prop and control panel to command relays with Arduino Mega 2560 or STM32 Nucleo-144 or Raspberry Pi board.

Relay Module Library for Arduino.

This project allows users to control their switches remotely through cloud.

A simple Arduino project to work with Single & Dual Relay modules with ESP01 ESP8266 With Simple http page & ArduinoOTA support to upload code from Arduino IDE wirelessly - No need to remove from relay module to program it

MotorLock is an Arduino-based project that controls a DC motor using a keypad and LCD display. The motor will only work if the user enters the correct password.

Create a Smart Energy Monitoring System that uses CT and PT to measure voltage and current, calculate the power consumption of electrical devices, and estimate the cost based on usage. This system will provide real-time data through a web interface accessible via a smartphone or computer.
