In this project, I've interfaced DHT11 with Arduino and then sending data of DHT11 which is humidity and temperature to phpmyadmin database.

You just bought a RGB LED strip kit and you would like to get rid of that cheap hand-held IR remote and to have REAL control.

This GrowBox Controller handles temperature, humidity, fan and lights, and configuration is made via web server. CSV logs and remote cloud!

Want to measure solar radiation but cant afford a Pyranometers? Well, make your own device with your Arduino board using this guide.

An attendance system based on Arduino and RFID reader which will save attendance data in real-time to Google spreadsheet.

This system monitors places where water could leak and turn the main water valve if any water leakage is detected.

Equipped with a keyboard, Ethernet Shield and LCD monitor, is able to execute built-in command and even to send command to a telnet server!
