Follow You...

I want to make a robot that follows you but it is stationary in position ... it can only rotate on it's axel to follow you... I figured a servo can be used to make the 360 degrees turn but then i read it can only get until 200 degrees... As for the the sensor I search and found that i can use a PIR sensor(motion sensor) or a color sensor (which is more preferred?)... I'm am less than clueless on how to make use of the sensor so that the robot will follow you.. The motion sensor will sense you moving but i don't know how to make it follow you

Breakdown

thanks…

 

I guess I’ll start off at first learning to use the motion sensors… to get a more familiar feel for it …
Then I’ll look for a continous rotation servos…
Do i need a microcontroller to connect them to be able to follow the motion?

Off topic

Can you use an Atmega328 w/ an arduino board instead of a PIC on the start here robot?

Yes you can…

Yes you can…

PIR sensor

I just bought a motion sensor to test out how to use it … 

I search google on how to test it out is the transistor necessary?

I just wanna try making an LED light up when i pass the sensor…

The sensor i bough is like this
