send_command(command)[source]#

Send a command to the Arduino device.

Arduino Code Documentation#

How to Use#

Send serial commands to control the servos:

Servo Control Commands#

Command

Action

‘a’

Open Servo 1

‘A’

Close Servo 1

‘z’

Open Servo 2

‘Z’

Close Servo 2

‘e’

Open Servo 3

‘E’

Close Servo 3

‘r’

Reset (all closed)

‘R’

Reset (all open)

Example Serial Input:

a  → Servo 1 opens
A  → Servo 1 closes
R  → All servos open
