• When the code runs, a secret number is produced but not displayed on the LCD, and what you need to do is to
guess it.
• Press the number you guessed on the remote control, then press the + key to confirm.
• Simultaneously, the range shown on the I2C LCD1602 will decrease, and you must press the appropriate number
based on this new range.
• If you got the lucky number luckily or unluckily, there will appear GAME OVER!.
Note: If the code and wiring are correct, but the LCD still fails to display any content, you can adjust the potentiometer
on the back to increase the contrast.
