I wanted to be able to control a servo with a 555timer ic. I got some help from the internet but almost all the designs iv tryed burnt my chips, or made the servo do unpredictable things.

After constant strugle and some help i finnaly got a good circuit of my design but it only goes from 180 to 90 and doesnt go the full way to 0.can you please help me!

***sorry for blurry image my tablet has a horrific quality camera***

 

Are you sure the servo can move the way you desire?

Most I have seen only go 120-130 degrees.

 

You already have a thread on this topic. One is enough, please.
