Autonomous obstacle-avoiding car using Arduino UNO and LEGO Techincs

Another obstacle avoiding car, but this one is using a LEGO Technics custom build, which seems to me to be a match made in heaven for Arduino, I don't understand why a lot more projects aren't using it tbh. I modified some LEGO power connectors for the Arduino interfacing, and used a stepper motor for steering.

Snake game

This is a snake game I m trying to make using the idea of Chrome dino game I am going to upgrade it but still this is the base or just a first phase kind of testing to see if it works. Link https://youtu.be/2Vw025xs81o?si=PTIURsxoaH6so-Rq

im making an adhd wrist smart watch to hold 100+ alarms and have nudges so i dont zone out

i know nothing about arduinos or electrical stuff so i dont know shi, only got like a bread board some m to m f to f and m to f wires 7 buttons ,2 vibrator motors one oled screen and a 7500 mah battery (might blow stuff idk) im not sure if i should get an esp32-c3 super mini or like a normal esp32-c3 cz idk if a super mini will hold all the stuff i got. help me out understand resisters and transistors (i got non) chat gpt say i need it but why 😦 and how many?

Self made dot matrix printer that recycles parts from an old or broken printer

Here is a partial image of what it looked like (I plan to redo the mechanics to use a proper printhead from a proper dot matrix printer (the original printhead in the shown unit was a modified one from a tiny shuttle impact dot printer))

Star Trek TOS Communicator

The microcontroller code is pretty basic in this one - I have an ATtiny85 controlling a DFPlayer Mini board over a serial connection in this prop replica which I 3d modeled, 3d printed, designed, wired, and coded. I'm very happy with how it came out.

Temperature controlled vents

295 lines of code, but it finally works! Little OLED screen to display temperatures and state. 2 temperature sensors to compare temps on either side. And 3 buttons, 1 to turn on the screen that times out after 15 seconds, and 2 to set heat or cool states. I know it probably isn't that impressive. But for my first coding and arduino project, I am very happy! Now to print a better vent and an enclosure for the arduino and put it to use!

Ultrasonic sensor “radar”

I like electronics, I like planes, this was the product. Been wanting to make this for a while, finally went and figured out how and made it.
