Self Balancing Robot – V4

It’s been almost 4 years since I started playing with self balancing robots posting about the very first version, then the 2nd really unsuccessful one and finally a really jittery / impossible to control 3rd version…

Now it’s finally time to show you something that actually works !

It’s long been since I gave up any pretense of usefulness for my projects / hacks… now all my projects are “art installations”… (except when it’s something for my 5 year old son, which is always a good pretext to play around with some electronics… 🙂 )

Stepper motor bluetooth serial driver

First Test using an Arduino (clone) board

Above is the image of my very first attempt of driving this nice little bi-polar stepper motor (M35SP-11HPK) that I had salvaged from a broken Canon printer a while ago.

I have quickly put together a L293D H-bridge with an Arduino board and using the Stepper library was quite straight forward

For the impatient you can see a (probably boring) video right after the break…
