This page explains how to build  
simple electronic circuits attached 
to a Raspberry Pi 1 and control them 
using Python scripts.

RPi 1 controlling LED with Python 2 script

  
Python 2 scripts:
 
led_blinking.py
 
from the desktop in RPi 1:
 
1. open a terminal window: 
2. sudo -s (you have to be superuser to have access to GPIO) 
3. idle 
4. File -> Open led_blinking.py 
5. Run -> Run module 

led3_blinking.py
 
from the desktop in RPi 1: 
 
1. open a terminal window: 
2. sudo idle (you have to be superuser to have access to GPIO) 
3. File -> Open led3_blinking.py 
4. Run -> Run module 


 
RPi 1 LED circuits:
 

 
Raspberry Pi 1 Model B (2014) - wired to one LED
RPi Model B LED circuit
 
 
Raspberry Pi 1 Model original (2011) - wired to three LEDs
RPi 3 LEDs circuit
