Musical Door Lock © GPL3+
Instead of using a keypad to open your front door or even your safe, why not control the mechanism by a slider that glides through pitches?
https://create.arduino.cc/projecthub/mmg220/musical-door-lock-51a87d
This project is designed to allow you to open and close a door lock that is attached to a push-pull solenoid. It uses a slide that is detected by the ultrasonic sensor to correlate the distance away from the sensor, to note frequencies. The “password” for this lock is all musical. You set the pattern for the password, in this case, C D E, and if this is correct, the door will open.

This DIY Wind Simulator Improves the Immersion of Racing Games
To enhance his racing sim immersion, particularly when driving open-air cars, Patrick Williams built this fantastic wind simulator.
https://www.hackster.io/news/this-diy-wind-simulator-improves-the-immersion-of-racing-games-5e9fe7a1e013
This wind simulator is, essentially, just a pair of big fans that blow towards the player. But the speed of those fans is actually linked to the car’s speed within the racing sim. Williams plays those sims while wearing an HTC Vive virtual reality headset, which provides complete visual immersion.
https://600000.ml/post/building_a_simracing_wind_simulator/
The Software
SimHub is relatively easy to use since it contains support for the Monster Moto Board, which we have a clone of. In Sim Hub, go to the Arduino screen and open the Arduino setup tool. Just make sure to select Arduino Uno and the Monster Moto Board and everything else should work out of the box.
Flash the Arduino and go to the ShakeIt Motors menu and the Motors Output sub menu. Connect your fans to the tools as shown below. You can click ‘Test now’ at the top to make sure everything is working correctly and figure out which channel is left/right.
Now head back to the Effects Profile section and turn on Speed and Speed with Curving. The default settings work pretty nicely, but you may want to adjust.
When I switch to a non open cockpit car, I disable the Speed options and turn Static Wind up to some higher amount.
I also recommend using a program called IRacingManager, if you use IRacing, and hook SimHub into it to start when IRacing starts.

Create a medieval-style robotic catapult with the ability to aim and launch at the press of a button.
The Robotic Catapult © GPL3+
A robotic catapult I threw together, with the ability to aim and fire!
https://create.arduino.cc/projecthub/tvtig/the-robotic-catapult-b42b9b
Ever have the sudden urge to create a medieval styled catapult out of really poor quality materials? Me too!
I used an Arduino to control 3 servo motors which drive the catapults rotation and firing mechanisms. I used a potentiometer to control the aim servo, and a push button to trigger the firing sequence.

A Simple Square-Wave Function Generator with an Arduino
https://www.digikey.com/en/maker/projects/a-simple-square-wave-function-generator-with-an-arduino/6d08a053484c4a909f15eced6c3fe433
Many makers rarely use the analog outputs on their Arduino, even though they can be useful in a wide variety of applications – such as dimming an LED. Most people have done that at least once, and countless tutorials use an analog I/O pin to drive an LED. This project shows how to connect multiple simple I/O components to an Arduino to create an uncomplicated function generator.

Living Pixels is a light frame that comes alive when you leave
https://blog.arduino.cc/2020/12/15/living-pixels-is-a-light-frame-that-comes-alive-when-you-leave/
Zekun Yang’s “Living Pixels” project illustrates this idea in luminescent style, as a picture frame that shows a static pattern of lights when anyone is around. When people aren’t present, it displays a range of emotions on its 16×16 LED matrix, from sleepy, to relaxed, and even angry.
