Awesome Arduino Projects | Arduino Project Ideas

Arduino 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 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:

Make This Joystick-Controlled Industrial Automation System

This project can be used to control up to four industrial electrical appliances with the help of a joystick and an Arduino Nano board.

ESP8266 Wireless Web Server

This ESP8266 based wireless web server project is built around an Arduino.

ESP8266 contains a built-in 32-bit low-power CPU, ROM and RAM. It is a complete and self-contained Wi-Fi network solution that can carry software applications as a stand-alone device or connected with a microcontroller (MCU).

This project is available at: ESP8266 wireless web server

Digital IC Tester With Embedded Truth Table

This article represents an Arduino based digital IC tester that is highly capable, highly reliable as well as cost-effective. Here, we develop a program with different functions for checking different ICs.

This project is available at: Digital IC tester with the embedded truth table

Arduino Based RF Controlled Robot

Here we present a simple Arduino based RF controlled robot that can be driven remotely. This robot can be built very quickly on a small budget. The RF remote control provides the advantage of a good controlling range (up to 100 metres with proper antennae) besides being omnidirectional.

This project is available at: Arduino based RF controlled robot

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.

This project is available at: Fancy lights controller

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.

The project is available at: PC based oscilloscope

Humidity & temperature monitoring

The IoT using Arduino microcontroller (MCU) is easy and fun for those who are new to the field. Presented here is a humidity and temperature monitoring using Arduino. In this article, humidity and temperature information from DHT-11 Humidity and Temperature sensor is analysed graphically on ThingSpeak platform using Arduino MCU and ESP8266 Wi-Fi module.

This project is available at: Humidity & temperature monitoring

Fingerprint sensor

Once you have all this electronic stuff around, you can’t let just about anybody into your workshop. This Fingerprint door lock helps you in keeping unwanted people away from your workshop. You want some engineer to access the workshop, you can add his credentials to the database and he would have access as well.

This project is available at: Fingerprint Lock

Automated plant watering system

This project is a simple and exciting plant watering system that you can build yourself in just a few hours. With efficient use of moisture sensor and downloadable component layout and source code, this could fit in perfectly for potted plants, be it on your terrace or the balcony or the front lawn. It works everywhere.

This project is available at: Automated Plant Watering System

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.

Earthquake sensor

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.

This project is available at: Earthquake sensor

GPS Clock

Here we describe a GPS clock based on Arduino Uno R3—an AVR ATmega328-based microcontroller board with six analogue inputs pins and 14 digital input/output (I/O) pins.
