Blink LEDs using Orange Pi Zero GPIO and Python

I have been covering quiet a few tutorials on using Orange Pi Zero and now we will see how to control GPIO pins and run a helloworld blink LED program using python.   The Orange Pi Zero comes up with a 2X13 pin slot very similar to Raspberry Pi style pinout. It does not come presoldered and we need to solder it ourself.

Hardware required

and a soldering iron if you dont have one.

Female header connector


I soldered the female header  instead of a male header pin since its very easy to handle with prototyping just like Arduino.


I have drawn the pinout just similar to the above pic

I have listed the  GPIO Pins out of these pinout

Logon to your Orange Pi Zero as root user using Putty or SSH client. and then run the below command to fetch and install the code

git clone
cd orangepi_PC_gpio_pyH3
python install

Now I will show you how to control the RGB LED using Orange Pi Zero.
For that you need an RGB Led, or bunch of single colored LEDs or a breakoutboard like
this will also do.

If you are building your own RGB led circuit you will need three 220Ohms resistor and an RGB LED

I am going to use Pin 6 for GND, Pin 3 (PA12), Pin 5(PA11), Pin 7(PA06) for GPIO pin
to control the individual colors. I modified the from the repository.

#!/usr/bin/env python
"""Basic blinking led example.


import os
import sys

if not os.getegid() == 0:
sys.exit('Script must be run as root')

from time import sleep
from pyA20.gpio import gpio

led = port.PA12

gpio.setcfg(led2, gpio.OUTPUT)

    print ("Press CTRL+C to exit")
    while True:
        gpio.output(led, 1)
        gpio.output(led, 0)

        gpio.output(led1, 1)
        gpio.output(led1, 0)

        gpio.output(led2, 1)
        gpio.output(led2, 0)

except KeyboardInterrupt:
    print ("Goodbye.")

    Great! It works as shown. I think that now I have a new brain for my robot with webcam, webserving, wifi and motor and sensor control for very little money. Thanks again.

    Thank you! Works like charm! Can you guys give me a clue how am I supposed to store data in database. I want to use MongoDB particularly. Thanks again! 🙂

    Hello how make FM transmitter with gpio orange pi zero h2+ please ? , cordially 🙂 .

      Hi sxlo,

      Thanks for you comment. I have once implemented a FM transmitter using Raspberry Pi. I am not sure about the Orange Pi, Rpi has inbuilt hardware support for operating the gpio at a higher speed which may not be there in Orange Pi but I will give a try to get this up running.

      The python dev package is missing, try after sudo apt-get install python-dev
