In this project, we will use Raspberry Pi to send command through GPIO to Servo Motor and control its rotation action.

If you don’t know what is GPIO layout, check our tutorial How to read Raspberry Pi i/o pin diagram (GPIO pin graph)


1 pc Raspberry Pi 2/3/zero raspi
1 pc 8GB MicroSD memory card preinstalled Raspbian OS. 8gtf
1 pc Servo Motor LACC2006AD-14
1 pc breadboard BREADBOARD
1 pc GPIO breakout kit(optional) breakout


Raspbian should be upgraded to latest version in order to support RPI.GPIO module
Please run following commands in shell:

Circuit Graph:

Caution: Unlike Arduino board 5V input voltage, Raspberry GPIO pin accept only 3 Volt. Wrong voltage input might damage the Pi board. Please be very careful!

download python code pi-servo.py
Please typing following shell commands to download python files( pi-servo.py):
wget http://osoyoo.com/driver/pi-servo.py

Finally, run following command in shell window:

sudo python pi-servo.py

You will see following manual in terminal window:
l = move to the left
r = move to the right
m = move to the middle
t = test sequence
q = stop and exit

You can type above 5 options(l,r,m,t,q) and control the servo motion accordingly.
