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.

Arduino based digital IC tester using MATLAB

Testing of digital electronic systems generally involves applying a set of test stimuli to inputs of the device-under-test (DUT) and analyzing responses of the system using a response analyzer. If the DUT generates correct output responses (also called the golden response) for all the input stimuli, the DUT is regarded as fault-free. Those DUTs that fail to meet the golden response are regarded as faulty or defective. This project describes a digital IC tester for testing 74xx series digital ICs using a MATLAB graphical user interface (GUI) drop-down menu based approach.

Earthquake sensor

This list of Arduino projects starts off with 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.

Light Animations Using Arduino and MATLAB

Light animations are visually appealing and hence widely used for advertising purposes. In this project given below, we present a MATLAB-based graphical user interface (GUI) approach to control the glowing pattern of a number of light-emitting diodes (LEDs). This project creates five different lighting patterns including ring counter and Johnson counter by clicking appropriate pushbuttons in the GUI. The blinking speed of LEDs can also be controlled using fast, normal and slow pushbuttons in the GUI.

Lawn mowing might be a bothersome task at times, but this next project is just straight up lazy. However, if you are that lazy, this next project might be the one for you. Statistics report a majority of people are uncomfortable with tying shoelaces, with about half of these don’t know how to. The effort taken to put your feet in tighten the laces and tie the knot might be too much. This next project built around Arduino does that for you. After Nike’s self-tying shoes, yours could be the one to hit the market. What do you think?

This project is available at: Automatic Tying Shoelaces

Walkie Talkie

Walkie talkies have always fascinated me. I used to wonder why don’t people just use their phones. Turns out it makes much sense to use a walkie talkie for them. These are bi directional modules dedicated for conversation between just them. How about you make one for yourself? This next Arduino project uses a Bluetooth for communication. All you’ll need are basic electronics supplies and an Arduino board. Hopefully, if your frequency crosses over with mine, we might talk?
