Facing angular movement issue. #8

Closed cis-apoorv closed 5 years ago

cis-apoorv commented 5 years ago

I'm trying to rotate the servo in a while loop by increment of 10 degrees on every iteration. I've set the acutation angle to 180 degrees, but when I tried to rotate the motor to 180 degrees it move upto a certain angle then stopped. I perform check on the angle then I found that whenever I set the angle of motor to 0 degrees it set the value of the servo to -0.36600244001626675.

When I set servo angle to 0-degree

>>> kit.servo[1].angle=0
>>> kit.servo[1].angle
-0.36600244001626675

When I set servo angle to 180-degrees

>>> kit.servo[1].angle=180
>>> kit.servo[1].angle
180.0

Can you please help me out with this?

Servos can be somewhat inconsistent and your code often needs some tweaking. You might have to adjust the min and max pulse widths. These guides might be useful: https://learn.adafruit.com/circuitpython-servo-tester, https://learn.adafruit.com/adafruit-motor-selection-guide/rc-servos, https://learn.adafruit.com/adafruit-arduino-lesson-14-servo-motors.

Thanks a lot @dastels sir! It is working like a charm. I've set the minimum and maximum pulse to 500, 2500 and now I'm getting perfect angular movement in the servo.
