Here I'm flipping the bit order coming out of a 74HC191 Counter IC. This happens all the time when you wire up something like this and then realize you wired the bits backwards (MSB last). With a normal breadboard, it's kind of a pain so a lot of times I'll just leave it backwards and hope I don't forget.
The new Jumperless firmware (1.3.5) can scan the board really quickly (~100 times per second) to look for the PWM signal coming from the probe. So now you can just poke out the connections you want to make and the Jumperless will make them into real hardware connections. No computer required. So flipping your bits is super easy.
You don't even need to make a probe like I did here, a piece of wire shoved into GPIO 19 will work too. And you just tap the wire to GPIO 18 to act as the button.
