This father-son duo built an Arduino-controlled Segway using motors from a broken electric wheelchair.
Making your own Segway, the Arduino way
https://blog.arduino.cc/2021/01/18/making-your-own-segway-the-arduino-way/
After obtaining motors from a broken wheelchair, this father-son duo went to work turning them into a new “Segway.”
The device is controlled by an Arduino Uno, along with a pair of motor drivers implemented handle the device’s high current needs. An MPU-6050 allows it to react as the rider leans forward and backwards, moving with the help of a PID loop. Steering is accomplished via a potentiometer, linked to a bent-pipe control stick using a bottle cap and glue

Gesture Controlled Interactive Table Light © GPL3+
https://create.arduino.cc/projecthub/rswm/gesture-controlled-interactive-table-light-3f8bd7
A simple gesture-controlled interactive table light, which can encourage kids towards making.
We all have seen different kinds of mood lamps & RGB light, most of them have some buttons or a remote to interact with them, but we thought of making a Gesture Controlled RGB Desk Lights which can change its colour only using a simple swipe gesture as a trigger. This is an interactive art project made using the Arduino Uno board & IR array sensor. It’s a fun and easy project which can be taught to students & kids.

Arduino-powered puzzle boxes help pop the question
https://blog.arduino.cc/2021/01/12/arduino-powered-puzzle-boxes-help-pop-the-question/
As a unique way to “pop the question” to their girlfriend, Redditor lmjd14 created a scavenger hunt for the proposal using a sequence of Arduino-based puzzle boxes.
The first box opens when one inputs a series of codes on a keypad, which relate to important relationship dates, while the second responds to holding down the correct buttons. The third involves a set of colored coins, and the fourth is activated with some RFID-enabled statues from the other boxes.

The Audiophonic Workbench – Recreate Early Electronic Music With Arduino
https://www.instructables.com/The-Audiophonic-Workbench-Simulating-Vintage-Test-/
This project is inspired by the early electronic music and sound effects produced by the BBC’s Radiophonic Workshop in the 1960′s. Before music synthesizers were commonplace a combination of industrial test equipment and tape manipulation were used to create previously unheard sounds. Test oscillators and ‘found sounds’ often provided the raw audio material that were looped, reversed, sped up and slowed down via multiple tape recorders to provide the eerie and unnatural sounds that accompanied the radio and TV productions of the time.
This project simulates three vintage style test oscillators using an Arduino microcontroller and can be built for less than £15. While it lacks the aesthetic charm and analogue sound of the real thing it retains the tactile, hands-on control missing from software plug-ins and is inherently hackable, updatable and repairable.

Create Custom Animations on 16×2 LCD Displays © GPL3+
https://create.arduino.cc/projecthub/tusindfryd/create-custom-animations-on-16×2-lcd-displays-025fb6
Easily display custom animated glyphs on 16×2 LCD using the createChar() function from the LiquidCrystal library.
The LiquidCrystal library makes it easy to use LCDs with Arduino. A particularly interesting function from that library is the createChar() function: you can create custom glyphs (characters), each described by an array of eight bytes, one for each row. The five least significant bits of each byte determine the pixels in that row. Writing bytes by hand to create art is not exactly an artist’s ideal process, so I have made a web tool in which you can draw the glyphs, and the code is generated for you.
