Hello,
I am facing a problem on my personnal project. Usually, I control a 5V servomotor using an Arduino delivering a 5V PWM without any problem.
Now, I am using a different servomotor with a 7.5V power supply (an external power supply, ground interconnected), and it doesn't work.
I assume that the problem is because the PWM isn't at the same voltage than the power supply of the motor. I thought about using a MOSFET to "pull-up" the PWM's voltage from 5 to 7.5V but I don't really know how to do that and whether it is a good idea or not.
Any idea ?
Thanks in advance !
