Well it’s time to present the main system for you all.
It’s upgraded from Arduino UNO to an Arduino Mega.
I have added some extra function to the system:
- A Terminal printer, to print out results and high score
- An SD card to store the result on.
- 2 more button is added (One OK button and one Select button)
- the NRF transmitter
- RTC Clock to hold the time
- A bigger Display, 20×4
