Hi there,
I would like to set up a circuit board which allows me to switch a PWM signal input like the image
There' s a PWM input (2sec period and 2ms duty cicly, standard servo rc pulses) which I should be able to push out directly to output when the arduino board is power off and completely stop when a trigger/board is on (digitalpin), obviously this task can be easily archieved with a transistor but I' m scared about noise it could make. I think I should use a optotransistor there, please let me know what do you think. Thank you in advance,
Pentium
... like the image ...
What image?

What noise?
