# Capture Ctrl+C so we can shut down nicely # The deadzone within which we ignore inputs, approximately 1/3 of total possible input The output via the Raspberry Pi terminal reads: 0Īlthough this only performs full-speed in both direction (as well as the calibrated "stop" speed of 90), I have successfully alternated from a full-speed to slower speeds, for example, going from 0 up to 90 in increments of 10.įrom the Raspberry Pi, I'm able to send input from my Xbox controller to drive the servo with a small custom Python script I've created along with xboxdrv (which works flawlessly with other projects I'm doing): #!/usr/bin/python Print (9) # Speed check (should read "0")

The sketch I've uploaded to the Arduino Uno is the corresponding sketch provided with the Python-Arduino-Command-API.
On the Raspberry Pi I have installed the following (although not all needed for addressing this problem):
#Servo motor arduino still serial
I'm attempting to communicate signals from the Raspberry Pi to the Arduino via USB using what I believe is considered a "digital Serial connection".
I'm not sure if there is a more efficent way of sending servo instructions via Python to the Arduino to rotate the servo.
I am having difficulty sustaining a connection between my Raspberry Pi (Model B running Raspbian) and my Arduino ( Uno) while sending signals from the Raspberry Pi to a continuously rotating servo (PowerHD AR- 3606HB Robot Servo) via Python.
