This is a demo of me using Jumperlab, an awesome UI written by Niklas Cathor to control a Jumperless.
Check out Jumperlab here:

And if you want a Jumperless, you can get them here:

If you want to know what's going on with the circuit, I'm just swapping out resistors and capacitors in a 555 circuit to change the speed of that blinky LED.
