Recently I bought a couple of Makeblock’s large servo’s. I am not really familiar with Makeblock’s products, I am a big fan of Arduino’s and Raspberry’s. But I have not used these servo’s before. For a project I’m currently working on I connected the servo’s as described in the scheme below.
But here’s the weird thing: everything worked for about an hour, both testing on 20cm as on the desired 12meter distance, just switching between 70 and 100 degrees. Unfortunately, one of the servo’s started ‘hitching’: it was just moving up and down a couple of degrees, very fast. Even helping manually did not resolved the issue. After switching off the power and the arduino and restarting everything, the servo completely stopped working. It just doesn’t do anything. Later the exact same thing happened to the second servo…
I’m guessing I’m making a very n00b mistake here but I am completely lost (is it even possible to control the servo using a normal Arduino, instead of the maker board)? So before blowing up yet another servo I figured to ask the experts for some advice, being you
Any thoughts and suggestions would be more welcome!
Edit: just had the chance to measure the output. Both the Arduino output as the other side of the 10m cable show the following. This is the kind of power cable AK5351 I used: http://www.kynix.com/Detail/238280/AK5351.html
