/* 8.40 - Grove - Project 2: Make an electronic dice
This sketch implements an electronic dice.
When you press the momentary button or touch the touch sensor, the electronic dice
will start to "roll", and then display your lucky number on the LCD.
During the roll, the gadget will produce a tone of changin pitch, to add to the
anticipation, and several random numbers will appear in the LCD.
Components
----------
- Grove Base Shield
- An Arduino Uno compatible board (such as Arduino/Genuino Uno or Seeeduino)
- Grove LCD RGB Backlight module
- Grove - momentary button or Grove touch sensor
- Grove - LED buzzer
- Three Grove cables
- Optional: a mounting piece of cardboard with nylon nuts, bolts and spacer.
IDE
---
Arduino IDE
Libraries
---------
- Wire.h (part of the Arduino IDE)
- rgb_lcd.h (Get it from https://github.com/Seeed-Studio/Grove_LCD_RGB_Backlight)
Connections
-----------
- Use a Grove cable to connect the button or touch sensor module to Grove connector D4.
- Use a Grove cable to connect the buzzer module to Grove connector D8.
- Use a Grove cable to connect the LCD module to Grove connector I2C.
