This project was made as part of an assigment of "Usos academics en terminologia específica en angles I" in which we where asked to build a small project with an Arduino Uno board.

We decided to build a card dealer for poker games (just for the challenge, we know it's not going to be better than someone actually dealing).

Step 1: What You'll Need

- 1 x Arduino Uno board
- 2 x Stepper motors 28byj-48
- 2 x Stepper motor drivers
- 1 x LCD screen 16x2
- 1 x IIC controller
- A bunch of jumpers (lots of them, you'll never have to many jumpers)
- 3 x 1kohm restistors
- 3 x push buttons
- 1 x welding board
- 1 x tin coil for welding
- 1 x welder
- 1 x wood sheet (420x297mm)
- 1 x PMMA sheet (210x297mm)
- 1 x Glue
- 1 x Pain (red in our case)
- 4 x Bearing (10mm inner diam)
- 4 x Nylon axis (15mm long 10mm diam)
- 1 x Stell axis (20mm long 3mm diam)
- 2 x gears (50 tooth and 10 tooth)
- 1 x rubber band

Step 2: Step 1: Build Your Circuit

Step 3: Step 2: Get Your Code and Test It!

The code is like supper beginer, but im very proud of it since its my first arduino code ever :)

(i'll try and enter more commentaries to it later on)
