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.
So let us check out these cool Arduino projects below:
Automated Washroom Light Using IR Sensors
This project-based on Arduino Uno and IR sensors 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 tubelight) will automatically turn on. When the person leaves the bathroom, the light will turn off.

Fancy Lights Controller
The fancy lights controller described here is built around the Arduino (an Open Source single-board microcontroller) platform that can be purchased in pre-assembled hardware form. The circuit is nothing but a portable four-channel, multi-mode digital light controller, realised using very few external components. Four LEDs are made to glow in different sequences and patterns, controlled from the Arduino board.

PC based oscilloscope
Here we describe how you can make your own oscilloscope at a very low cost using your PC and an Arduino board as the hardware for signal acquisition. You can use this oscilloscope to capture frequency signals up to 5kHz. The Arduino board, the heart of the oscilloscope, reads the values from its inbuilt analogue-to-digital converter (ADC) and pushes these to the PC via USB port.

Enjoy This Wireless 3D Mouse And Keyboard
In this project, we are going to make a 3D wireless HID device that will give you a whole new experience of using computers and playing online games using an Arduino Pro Mini board.
In this project we would be constructing an earthquake indicator. A highly-sensitive ADXL335 accelerometer is presented that can indicate vibrations. If motion is violent enough during an earthquake and crosses a certain threshold, a local alarm light (LED) glows, a buzzer sounds and a relay energises. With certain modifications, this can be turned into a knock-and-shake detector for ATMs, vehicles or door-break alarms as well.
