Kickstart Raspberry Pi With Python

Introduction

In this article, I will show you how to work with Raspberry Pi using Python. Python is a wonderful and a powerful programming language that's easy to use (Read and Write) with Raspberry Pi.

 

What you will need

• Raspberry Pi configure with GPIO library
• 1-Small led
• 1-50 ohm Resisitor
• Some solid core wires
• Bread Board 

Let there be light

Before we get around to write the code, let's first get acquainted with the pin numbering of our RPI and create a simple circuit. 

• Pin 1 (+3.3v) should go to longer led to the led Pin.
  
  
• Attach the shorter led pin to the resistor and finally attach the other end of the resistor to pin-6(GND) on your RPI.

Controlling the led with our python code

 

I like to write Python code in IDLE IDE because it comes packaged with Raspbian distribution as it's free and allows to write to our cod a little bit easier than Python command line or a text editor.

• Power on your RPI and boot all the way in the operating system GUI.
• Open the terminal and launch the IDLE IDE. 
• Click File > New to open a new window.

Code

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
GPIO.setup(1, GPIO.OUT)
GPIO.output(1,True)

1. Import GPIO library
2. Use board pin numbering
3. Setup GPIO Pin 1 to OUT
4. Turn on GPIO pin 1
