the purpose of this project is to turn an led on and off using a rapberry pie and the command line
raspberry pie,monitor, keyboard, data cable, hdmi to usb cable, network cable
The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.[7][8][9][10][11]
The Raspberry Pi is manufactured through licensed manufacturing deals with Newark element14 (Premier Farnell), RS Components and Egoman. All of these companies sell the Raspberry Pi online.[12] Egoman produces a version for distribution solely in China and Taiwan, which can be distinguished from other Pis by their red coloring and lack of FCC/CE marks. The hardware is the same across all manufacturers.
Create a GPIO file access: echo 11 > /sys/class/gpio/export Configure the Pin Direction (In/Out): echo out > /sys/class/gpio/gpio11/direction Write a value to turn on the LED using the GPIO11: echo 1 > /sys/class/gpio/gpio11/value Now your led should be ON!!! Write a value to clear the LED using the GPIO11 echo 0 > /sys/class/gpio/gpio11/value Now your led should be OFF!!! Delete the created GPIO (11) echo 11 > /sys/class/gpio/unexport You are able to access to GPIO using python or any programming language. We wrote a python script to show how.
