LED Slot Machine este un mini joc distractiv in care 3 LED-uri se aprind intr-o culoare la intamplare. Scopul jocului este de a avea toate LED-urile aprinse in aceeasi culoare. In momentul in care castigi, muzica incepe sa cante iar pe ecranul LCD iti apare un mesaj.

Ideea a pornit de la varianta clasica de slot, dar facuta in asa fel incat sa fie cat se poate de fair.

Block Scheme:

Components List:

• 1x Arduino Uno,
• 1x Breadboard,
• 3x LED RGB,
• 1x Push Button,
• 1x Ecran LCD I2C,
• 1x Buzzer

Electrical Schematic:

Libraries Used:

The only library needed was the one for the I2C LCD.

liquidcrystal_i2c.rar

After many tries, I made it so that the game works. Now, when you press the button, the RGB's turn on into a random color.

If all 3 RGB's have the same color, the buzzer will start singing and the LCD will display a different message.

Soon, I will put it to use and make my friends pay in order to play with it.

The project was very interesting. I learned alot of new things, how to use arduino, and how to search things better on the internet.

After this project, I wish to do more arduino projects in the near future.

I started by doing the project in Tinkercad, so that I can do trial and error there.

I started thinking how should I arrange it so that it's not messy and I found the solution.

Without realising it, the project was already done.

The code:

The libraries:
