Triple Servo Tester

thingiverse

I'm currently crafting several robotic walkers, all driven by servos. The challenge then emerges in determining the extent of motion with each one and also the range of motion accessible. I have a few crude testers, but needed one that displayed the actual Arduino servo position number, from 1 to 180. This means I can manually adjust and record the values. An Arduino, three pots, some pins and an SPI OLED along with a JST are required, plus a cheap power converter to ensure that everything runs at 5 volts. I initially started 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 worn look. I also made some scratches and cuts and painted them silver to give the impression of a metal box and dirtied up the knobs. A glass cabochon was used as a screen bezel.
