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.

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.

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

Projeto utilizando um Arduino, para acender uma Lâmpada com sensores de distancia

Relay Module Library for Arduino.

Arduino için Role modülü

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.

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

Arduino Based Smart Remote for Controlling Electrical Appliances a part of the Final Year Project at P.S.V Polytechnic College

Coupling the power of metal detection technology with the efficiency of a conveyor belt, this system enables seamless detection and removal of metal contaminants from material streams, ensuring product integrity and safety in industrial applications.

IoT-based Smart Home Automation project to control 8 AC appliances and a smart door using ESP32 via Touch, Bluetooth, and Cloud with custom Android app.
