Control C36R servo using PIC16F88

[yeekang92]

Hey guys,

I'm new here and I need your help. I'm doing a project which requires to obtain an input in circular motion and I've decided using potentiometer as the input. With PIC16F88 as the micro controller how should I program it to read the input from the potentiometer and then generate an output to the servo motor? Do I have to buy a servo controller similar to the video below? Thanks in advance

how many pcs of sevo u are goin to control. the rc servo is controlled by pulse width, so if are controlling alot servo then probably u will need the servo controller.

I only got 1 servo to control. so it means that I dont need to get that servo controller? and can you teach me of how to do the programming similar to what he is doing in the video? Thanks alot

Do some study on:
1. How to read the analog value from the potentiometer.
Example:
http://tutorial.cytron.com.my/2011/08/09/project-4-%E2%80%93-analog-sensor-potentiometer-bb-psj/

2. How to control the servo motor.
Example from sample source code:

Only then you try combine both in one code to get what you want. I also found out that the DIY project http://www.cytron.com.my/viewProduct.php?pid=HSwOBiUpOBAaOR0OAjEDJfMqSBbl1cpR/xbsOOT6uNc=&store= is similar to your project but they are controlling stepper instead of servo motor.

Servo Motor use signal 50Hz. PWM module can't generate this low frequency. Then, can use Timer Interrup to generate the pulse. Maybe, interrupt is difficult for beginner.
