Further Exploration

You can slightly modify the hardware and software based on this experiment to make a

dice. For hardware, add a button to the original board.

Build the circuit:

Next, go to 11_Segment, and compile dice.c

gcc dice.c –o dice –lwiringPi

Run

sudo ./dice

Now you should see a number flashing between 0 and 6 quickly on the segment display.

Press the button on the breadboard, and the display will statically display a random

number between 0 and 6 for 2 seconds and then circularly flash randomly between 0 and

6 again.
