Be nice to your old or unused hardware (I just built someting :) )

I just saw a sad Sad, little Arduino Pro Micro laying around today. It was one of the first devices I had to try around with microcontrollers. I thought about if it can be useful for something. Some time ago I saw a capactior-tester based on an Arduino on the web http://shelvin.de/kapazitaeten-von-10nf-bis-2000uf-einfach-messen-mit-dem-arduino/ (it's in german). As I still have a very old and very basic (you could also say crappy Cheesy) multimeter, that doesn't support mesuring capacitors, I just built a small device with the Arduino and an 1602 LCD. I haven't written the code by myself, I just copied it from the website above and added some code, so the results are shown on the LCD instead of the serial-console and a LED flashes when the mesurement is completed (it takes some time, if you have a large capacitor). If the LED disturbs it can be deactivated via a jumper.
I just made some pictures an a video so you have something to look at Smiley. I hope the small Arduino feels a bit happier now Wink.

I bet it feels 8-bits happier Cheesy

Nice job!
