He connected the Arduino Mega’s LED output to a pair of LittleBits which then switch a servo between two positions.

This circuit is not the very latest in robotics, but it may be of interest to those of you involved in making little robots using popular and inexpensive components. The proposed idea is a ...

He built a servo tester and demonstrator based on an Arduino, and went the extra mile to give it a good UI and a bunch of functionality.

Servo moves smoothed - this could be an interesting one if you work with robotics. And it is flagged by the Arduino team.

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on ...
