How to power servo without driver/arduino? Answered
I'm trying to make a servo motor spin without using a driver or micro controller, I just want to power it directly.
It doesn't need to move a specific distance, or be precise.
How would I wire this up?
The idea is to power it on by using a HC-05 Bluetooth module, either directly, or by optocoupler.
It would have to trigger the servo on whenever a Bluetooth device that has already been paired connects to the HC-05 module (in wireless range), and then off when a Bluetooth device disconnects (out of range).
My idea is to use an app that automatically plays an audio file through the HC-06 when it connects (this app already exists), and that audio file happens to be the correct frequency to act as a PWM signal.
Is this even possible?
