Hi~ I am student from Kang Chiao International School, I am going to introduce how to make an Arduino Dice.
Refrence:
https://www.instructables.com/id/Arduino-Dice/ I change the time that the LED brightens.
Prepare Materials
What you will need:
18 Jumpers (11 large 7 small)
7 LEDs (I used red ones)
PushbuttonResistor (I used 100ohm, 10 ohms would work too)
Solderless breadboard Arduino (+usb cable for connection)
Optional: small strap-down copper jumpers
Tools: Wirecutter computer.
Connect LEDs and Jumpers to Board

Connect all jumpers and LEDs to the Board. (negative sides)
