Arduino (an Open Source Hardware) has been a revolution ever since it struck the market. Arduino or Genuino (as known in some places), has been a very lucrative option for students designing their first projects. This increase in interest is causing a lot of people to tinker with technology themselves.
We compiled a list of DIY Arduino projects that would be cool to design. If you have an Arduino lying around or are planning to buy one, these should come in handy. All you need is an Arduino board and some basic electronics supplies.
This project is based on Arduino Uno and IR sensors and is used to automatically switch on and switch off a washroom’s light that works on AC mains. Whenever a person enters the washroom, the light bulb (or tube light) will automatically turn on. When the person leaves the bathroom, the light will turn off.

In this project, we would be constructing an earthquake indicator. A highly-sensitive ADXL335 accelerometer is presented that can indicate vibrations. If the motion is violent enough during an earthquake and crosses a certain threshold, a local alarm light (LED) glows, a buzzer sounds and a relay energizes. With certain modifications, this can be turned into a knock-and-shake detector for ATMs, vehicles, or door-break alarms as well.
