Interference or ???

Dear all,

In our project we have a hacked continous servo.
We can controll this servo with bluetooth but even with IR.

IR give the problem, it react not stable.
The led on our IR module is always on, so means receive always code.

What could be the problem?

We thinking interference from somewhere, but not sure how to solve it.

Any help?

Regards,

David

Better decoupling and shielding.

IR give the problem, it react not stable.

Look at the servo signal with an oscilloscope and the servo removed. Is this a stable signal? If not the the constant looking at the IR is interfering with the software generation of the servo signal. Switch to using a hardware generated servo signal.
