Arduino Slot Machine.

You like gambling ?And you don't want to spent a cent? If the answer is yes then this project is for you...

Supplies

1. Arduino
2. 16*2 LCD display
3. push button
4. piezo speaker
5. 10kR resistor
6. some jumper wires
7. breadboard
8. USB ca

Step 1: The Schematic.

Wire the components like the scheme.

Step 2: Arduino Code:
