What is a Raspberry Pi? What can you do with a Raspberry Pi? How do I start with a Raspberry Pi?
Join me as we explore this single board computer. We will discuss what it can do, and how to interface to the outside world. In the process we will discuss how to setup a new board, and how to gave a remote Raspberry Pi for use over the network.
Lastly we will build and program a small circuit to get your hands engaged in a real application. I will not pretend to be an expert, but mearly a leader in the exploration of this micro-controller.
The home of the Raspberry Pi Home is a good place to look for information.
Lets have a look at at Presentationon about the PI.
Now lets watch a Live demo of what to do at startup.
This is a VERY simple example of code for the Pi, but it will help to make clear how to code the Pi. The basic setup is to connect the Plus side of and LED (long pin) to pin 11 on the Pi. Then connect a resistor to the LED (short pin). And then connect the other end of the resistor to ground. *This example is taken from LED Blinking with Raspberry Pi.
Here is the code we will be running.
import RPi.GPIO as GPIO import time # blinking function def blink(pin): GPIO.output(pin,GPIO.HIGH) time.sleep(1) GPIO.output(pin,GPIO.LOW) time.sleep(1) return # to use Raspberry Pi board pin numbers GPIO.setmode(GPIO.BOARD) # set up GPIO output channel GPIO.setup(11, GPIO.OUT) # blink GPIO17 50 times for i in range(0,50): blink(11) GPIO.cleanup()
