Subject: [AVRButterFly] Looking for guidance with motors/servos


Hi All,

I am a newbie to electronic chip programming. I am building a device that
requires motors to rotate for fixed segments of time and servos to rotate at

fixed angles. The AVR butterfly chip was recommended as a good place to
start. I am familiar with some C from college so hopefully I can manage
that. I need to program the AVR Butterfly chip to perform the following
tasks:

1. Run two 12v motors for 20 seconds and stop.
2. Rotate a small toy servo motor to 180 degrees, 270 degrees and back to 0
degrees for 10 seconds each.
3. Run another 12V motor for various segments of time based on feedback from

pressure sensors.

Can someone please help me with the following questions:

1. I would appreciate a recommendation on any online tutorial that can help
me get started with AVR butterfly and motors.
2. How many servos/motors does a single AVR butterfly microcontroller
support? I have a requirement to support 4 servos.
3. Can some one please point to a particular servo/motor controller that I
can use to achieve the results.

I'll greatly appreciate any help. Thanks in advance.
