11 Arduino Projects – They built what!?

Ever wondered what you can do with Arduino? Are you wondering if Arduino can work for a project that you have in mind? There’s so many cool things that you can do with Arduino, and we’re here to show you just how versatile Arduino can be!

In this video, we’ll show you 11 Arduino projects that our members have built.

Some of them are about home automation, some of them are just off the wall. We chose to feature these specific projects because we think they’re the best Arduino projects to show off the capability and variety of things you can do with Arduino.

All the projects shown here were submitted by members of Programming Electronics Academy. They all put a ton of work into making these, and we are proud that we were a part of that journey.

If Arduino has you excited and you think you want to give it a shot, make sure to stick around for the next video where we’ll guide you through choosing the right Arduino board, including all the options out there, and the must-have accessories for getting started programming and building with Arduino.

Project 1 – Arduino Hover Disk

This first project is an Arduino hover disk. While it doesn’t exactly hover, it sure gives the appearance of hovering. And you’ve got to love that Captain America paint job.

Arduino Hover Board

To build it, Dan used two Arduinos, two XPs, a Sabertooth motor controller, a latching relay, a power relay shield for Arduino, an audio effects sound board, two wheel chair motors, a bunch of batteries, and a ton of LEDs of course.

Dan’s a retired school teacher, but he used to ride this around the school halls. That would have been really fun to see.

Project 2 – Trident

The second project is a six foot tall, NeoPixel blazing, polycarbonate trident.

Arduino trident

It’s used to cheer on the home team at First Robotics Competitions. It was made by first FRC team 4296 Trident Robotics, whose mentor, Mark Bala, was a member of Programming Electronics Academy.

It’s made of polycarbonate tubes and sheets. It uses 12-volt DC neopixel strips, each of which has three RGB LEDs per pixel. There is a total of 70 pixels or 210 LEDs in this trident.

There is an Arduino nano on the right side of the head that controls the LEDs and also connects to an SD card reader where the LED patterns are stored. The trident also uses two SparkFun 9 Degrees of Freedom inertial measurement units

These two sensors communicate to a separate Arduino nano so that the trident can detect different movements and adjust its display accordingly.

Project 3 –¬†Christmas Tree Defender Cat Diversion Laser Turret

Yes you heard that right. This third project is a tool for diverting cats from a Christmas tree. The project was made by member John Hart. It uses an Arduino Uno and a motion sensor which triggers two servos on separate axis to move a laser pointer around. Apparently, it works like a charm.

Project 4 – Wireless monitor of Solar Geyser performance

James Trace wanted to monitor the performance of his Solar Geyser which is like a heat exchanger for hot water.

He used an Arduino nano and a bunch of sensors to measure ambient temperature, humidity, sunlight, and then he used an ESP 8266 to wirelessly send all that data to ThingSpeak, a cloud sever for data logging, so he can log that data and see it from anywhere in the world.

Project 5 – RV Camper-Van Power Cabinet Fan Controller System

This project was made by Jack Tinsely. He had a really cool van that he transformed into a camper.

Arduino project to regulate RV cabinent

Jack used an Arduino to build a system that measures the auxiliary battery voltage, reads the temperature of the power cabinet, operates a cooling fan as necessary, and transmit this information wirelessly to a second Arduino that displays the data on a screen so he can easily read it while he’s driving.

Project 6 – Home brewing with Arduino

Ever done any home brewing? If you have, it’s hard not to have the Arduino pass through your mind as a tool to help in the process. This Arduino home brew project is the result of a ton of hard work and dedication from Klas Bergmen.

Arduino Beer Brewing system

Klas used an Arduino mega, temperature sensors, SD card reader, LEDs, and Ethernet connection and more to make one heck of a fermentation control and monitoring system.

And did we mention he sends all this data to ThingSpeak?



Project 7 – Arduino controlled aquaponics garden

Dimitrius has a three tank aquaponics garden that he wanted to automate.

Arduino aquaponics garden

He needed to feed the fish from a hopper, turn the grill lights on and off for the plants, pump water through filters, and fill the plant tanks with water.

He was able to this with an Arduino Uno, a water level sensor to detect whether pumping between tanks was necessary, a four channel relay module, pumps, and servos.

His Arduino program is able to control all those electronics, and he was pleased that after only six weeks and having never coded before, he was able to get this project working.


Project 8 –¬†Workstation Simulator

Jim works at a power plant and is responsible for training new technicians. He built a simulator using Arduino for a common work station at his job.

Arduino Powerplant workstation simulator

The idea was to give students the chance to simulate operation prior to performing on the actual unit. He used an Arduino Mega and a ton of gauges.

Project 9 – Arduino sound-to-light NeoPixel display

Robert aligned 25 strips of WS2812 also known as NeoPixels, resulting in a 450 point matrix. The display of the matrix then adjusted based on sampling audio input.

For the code, he used pre-built arrays to save different patterns that are shown.

Project 10 – Arduino Smart Living Project

Devore is a teacher of STEM program in Vukovar, Croatia.

He introduced his students to Arduino and through his mentorship, they were able to create this small scale interactive model of a smart city. They used an Arduino Uno to control servos and LEDs to read outputs from light sensors to create the model.

Arduino Smart Living Project

This project went on to win the World Arduino Day community challenge in the category of kids and education.


Project 11 – DCF77 Analyzer Clock

Eric built and programmed this amazing piece of hardware.

Arduino DCF77 Analyzer Clock

It’s an atomic clock that displays the timestamps of received pulses and also displays the details of received pulses such as pulse width and pulse length.

He used an Arduino Mega, an Arduino Uno, tons of LEDs, seven segment displays, an Adafruit sound effects board, and more to make this project come to life. Pretty amazing if you ask us.
