I want to make the circuit useing 2 555 timer ics any servo control diagram i have ever copied from the internet doesnt work. My book (practical electronics for inventors) shows the same bad curcuit. I had to rely on my instincts which helped but i didnt get anything practical. All i need is a circuit that can move my servo -90 to 0 and 0 to 90 and back with a few buttons. Can you help me?

 

Servo valve or motor and the specification?

 

hi La,

Qualify 'Servo' it means different things to different people.
There are RC servo's and Motion control servo's which are typically controlled totally differently!

What app or website did you use the build and test this diagram? It will come in handy for me latter and i could save a few ic's im going to try it now

It just makes loud squeaking noises and i dosent move

 

Servo valve or motor and the specification?

Its an sg90 nothing special on the data sheet

 

Nvm it moves just one way
