This was made to show how one would power up a microcontroller and read all the pins. There are a few ways to do this, but the simplest one is to use the Arduino Nano running some sort of logic analyzer sketch that prints the state of all the pins to the serial monitor continuously.
The other option would be to set the ADCs on the Jumperless itself to read all the pins and multiplex the 4 ADCs to all the pins really quickly. But so far, I haven't written a nice way to do that over serial.
