A DIY automatic card dealer.

Currently the only feature is dealing cards, I would like to implement other features listed below, but most would need a redesign. I decided to upload this one since it works well and does it's job, but as every project could be improved upon forever.

Possible Improvements, Features (maybe v2)

• Rotary encoder: Currently uses a single hall effect sensor for homing. Then does a full rotation while measuring the time it takes to rotate 360°. That time is then divided based on number of players, which has a few disadvantages and isn't as precise as measuring an amount of rotation directly. This could allow up to even 8 players due to more precise card throwing.
• Smaller, less power hungry micro-controller: Currently uses 30 pin ESP32, but it could get away with ESP32-C3 which uses much less power and is still reasonably powerful.
• Better buttons
• Better sliding mechanism: It works fine, but could be improved.
• rotation without bottom as a separate part
• Battery indicator: Have a battery indicator on the screen.
• Built in battery: Currently uses 4 AA batteries, but it could have a built in battery and a USB charging port.
• Different board mounting: With a smaller micro-controller, the board could be positioned lower and extensions for hall effect sensor legs wouldn't be necessary. 
• Faster: Maybe a faster motor or minimize waiting time in between throws, but that would require a rotary encoder.
• Pulling individual cards: Hosting a web server on the ESP32, you could set position relative to the dealer and pull a card by pressing a button on the screen.
