Information
The purpose of this project is to create an electronic version of Beer Pong. The system keeps track of each player's score and BAC(Blood Alcohol Content).
Parts Needed
- 1 x uLCD-144-G2
- 1 x MPR121 Capacitive Touch Keypad
- 6 x Photoresistor
- 14 x 10k Ohm resistor
- 3 x Blue LEDs
- 3 x Red LEDs
Pinout
Reminder!
Remember to pull up I2C bus and implement voltage divider circuit for each Photoresistor.
