Automated Water Irrigation System, A scalable, Arduino-based irrigation system optimized water usage by leveraging soil moisture sensors to automate solenoid valves and water pumps. A well-designed pipe network minimized water loss, while Wi-Fi, Bluetooth, and solar power enabled remote, energy-efficient operation. The system reduced labor, improved efficiency, and boosted yields, with potential for AI, IoT, and machine learning enhancements., Arduino (Uno, Mega), soil moisture sensors, flow sensors, temperature and humidity sensors, solenoid valves, water pumps, servo motors, Wi-Fi module (ESP8266), Bluetooth module (HC-05), solar panels with battery backup, Arduino IDE (C/C++), pipe network, pressure regulators, LCD display, remote monitoring via web/app integration Synchronized Desktop Calendar, Developed a desktop calendar with globally shared and synchronized calendars, allowing users to schedule meetings with other users., C#, .NET, SQL, XML
