Simple Room Temperature Controller with Arduino
Households and workplaces have become some of the most common places to spend most of our day. Regardless of the size or space available, it is imperative that these spaces be made as comfortable as possible to have a suitable environment. The key to indoor comfort is to keep the space at a constant temperature.

Automatic Light Control System with Arduino LDR Sensor
Most places around cities, towns, highways and even estates are lit during dark hours or at night in most regions of the country. Manual control of these lights can prove to be difficult and at times inconvenient. One of the solutions that are most commonly used is timers, however, this approach can be quite limited in some time zones where the length of day varies throughout the year. Thus, a more prudent solution is needed.

Smart Irrigation System using Arduino
In order to effectively use water for irrigation, sensors technology and Arduino have been combined to create an automated irrigation system. The farmer will be able to manage irrigation using a or smartphone from any location at any time, monitor water parameters, and save time and effort while also optimising water consumption.
