Triple Servo Tester

thingiverse

I'm currently building several walking robots, all powered by servos. The problem then arises in working out the extent of motion with each one and also the range of motion available. I have several dumb testers, but needed one that displayed the actual arduino servo position number, from 1-180. This means I can manually adjust and take down the values. An arduino, 3 pots, some pins an SPI OLED and a JST is required along with a cheap power converter to ensure that it all runs at 5v. I initially started out with a plain box, but then thought "What would Adam Savage do?" and so added some design details, sprayed it in primer and with various inks and weathering powders gave it a used look. I also made some nicks and cuts and painted them silver to give the impression of a metal box and painted and dirtied up the knobs. A glass cabochon was used as screen bezel. code available : https://www.instructables.com/id/Arduino-Triple-Servo-Tester/
