Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as ...

In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC.

Now you can build your own simplest RC servo tester! Here is the circuit wired around the popular timer chip LM555, configured as a low-frequency astable multivibrator which can provide good control ...

Depending on what you’re doing with servos, you might want a different kind of testing suite. Here’s one that’s geared toward RC pilots.
