Hi All,

I've got a couple of questions about the butterfly microcontroller and would
appreciate if someone can provide info.

1. How many servos and sensors can be attached to the microcontroller
simultaneously?

2. Is there a limit on the operating voltage of the servo that the butterfly
can handle? I am planning to get 5 high torque servos shown in this link and
use it with the butterfly microcontroller:
http://www.basicx.com/Products/robotparts/Servo1.htm Not sure if this will
be compatible.

Thanks again,
Raza

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.
