Servo motor control
Hi, I want to create a servo controlled unit which can control opening and closing of the sliding doors automatically. I have never used or bought a servo motor before so I will need all the help I can for this project. I would like to know:
1) Which kind of servo motor can I use for this project?
2) I saw few servos on internet and they have different number of wires comming out from them, i.e. some have 3 wires and some upto 8. What is the difference?
3) Any suggestions on how to control it using PIC & which PIC would be suitable?
4) I have noticed at few building having this kind of system, the doors slide slowly when opening and closing towards the end i.e. near to when they are fully open or close. How is that achieved?
I will buy one servo based on the answers and begin my project accordingly. I appreciate all the help in advance. Thanks
