Wobble Wagon

Inspiration

Got inspiration from Mario Kart Racing and wanted to bring it to real-life with power-ups and how you can use them to mess up other drivers.

What it does

It's a "Kart" that can be controlled via a wireless controller. The controller has a screen which notifies them that they have the debuff applied to them and then has various buttons to apply a debuff on another player.

How we built it

We used 2 - ESP32 C3 modules that communicate with each other using the ESP-NOW protocol. We used a voltage divider circuit to make 3 different buttons go to one pin to read different inputs so the arduino can give the debuff the other player.

Challenges we ran into

The batteries were not supplying enough current to the car making it unable to move properly.

Accomplishments that we're proud of

Designing a wireless controller that can control the "Kart" to move forwards backwards and turn left to right. Designing a 3-button system that can interact with the Arduino to display images and text on a oled display. Having the Arduino power the motor driver to drive the motors.

What we learned

How to use the esp 32 for wireless communication and supply voltages to various devices, how to drive DC motors using an Arduino, how to design a multi-input system that only needs 1 pin to recognize the difference between inputs.
