install/update GPIO (GeneralPurposeInputOutput)

https://sourceforge.net/p/raspberry-gpio-python/

sudo apt-get update
sudo apt-get install python-rpi.gpio python3-rpi.gpio

get an overview of the pin layout:

pinout

GPIO examples:

Basics:

• GPIO
• Basic usage
• Outputs
• Inputs

lets make GPIO control a LED:

you need:

• 300 ohm resistor
• LED
• Breadboard
• jumper cables

add pic of circuit

start python the IDE:

python

enter every line with a return

import RPi.GPIO as IO
IO.setmode(IO.BCM)
IO.setup(18,IO.OUT)
IO.output(18,IO.HIGH)

or
IO.output(18,1)
or
IO.output(18,True)

lets make GPIO read an input:

you need:

• 10k ohm resistor
• button
• jumper cables
• Breadbard

add pic of circuit

start python the IDE:

python

enter every line with a return

import RPi.GPIO as IO
IO.setmode(IO.BCM)
IO.setup(4,IO.IN)

get status of the pin:

IO.input(4)

button connected to pin 4. button not pressed returns 0 - button pressed returns 1
