Interactive device

Date: March 28th 2023

What if we could make it snow whenever we want?
Well, we are not quite there, but we can still control the snow falling on the screen with this interactive device:

This project, named "Snow maker", combines an ESP32 with a joystick and a button that communicates with the computer through a cable c. If it is snowing, pressing the button will make the snow stop. On the contrary, if it is not snowing, pressing the button will make the snow start falling. The other functionality is with the joystick. Moving the joystick changes the color of the sky. Each direction (x, y) changes the amount of green and red (it is RGB color model, blue is set to 255) that are present in the background.
This device has a blue enclosure, built with a blue cardboard paper. Here's what the enclosure looks like:



To make the box, I used a ruler to divide the cardbox into four pieces (top, bottom, left and ride sides), as well as a small pieces at the end to allow for closing the box. The box can be closed with tape and/or glue.



Inside the box, we have the EPS32, a breadboard, a joystick and a button:



The joystick port SW was connected to the ESP32 port 17, port VRY connected to port 13, and port VRX connected to port 12. Furthermore, the joystick is connected to the ground and the 3V port. The button is connected to port 21 and ground.
