About this product
An electronic dice with seven LEDs arranged like the pips of a die. Pressing the button makes the LEDs flash random numbers, then slow down and stop on a value from 1 to 6, lighting the matching pattern. This expansion version contains the breadboard, LEDs, resistors and push button, but not the Arduino board or USB cable.

Frequently asked questions
Does this kit include the Arduino board?
No. This expansion version includes the breadboard, LEDs, resistors and push button only. You need an Arduino Uno or compatible board with a USB cable, or the full kit version of this project, which includes them.
How are the LEDs protected from excess current?
Each LED has its own 220 Ω resistor, which limits the current drawn from the Arduino output pin.
