Use keyboard to control servo via keyboard input

[tydraestor]

So i have a sparkfun pro micro, and i want to be able to move a servo back and forth to control a camera from my computer via keyboard input, i have no idea where to start. I an very new to arduino and my science teacher asked me to do this for a security camera

I'll presume you already know how to wire servos properly (Needing external power)

 

What I'd do is get a bluetooth or wireless component for the arduino & get a bluetooth piece for the computer. Once I have that, I'd program a way to have the computer talk to the arduino using bluetooth. 

 

You'd have to write one program for the Arduino & one program for the computer.

Look into the PWM outputs. You'll use that to control your servo. In theory you should only need to hook your yellow servo wire to one of the PWM outputs (and a separate power source) and write some code to send the right signal to the servo. It's been done before, Google is your friend in this case. 

 

Once you have worked out how to control it through your arduino, it's a simple case of changing a variable via keyboard input.
