Today was the first day I opened my Raspberry Pi. Upon my first time opening it I was given the task of making an LED turn on via a bread board and command lines. The positive side of the LED connected to GPIO2 and the negative side connected to a 220 ohm resistor which was connected to the GND (ground) of the bread board. The command lines needed to initiate the task are as follows:
sudo su
echo 2 > /sys/class/gpio/export
cd /sys/class/gpio/gpio2
echo out > direction
Those commands told the pi where the LED was connected on the breadboard. the code needed to turn the light on is: echo 1 > value. The code needed to turn the light off is: echo 0> value. To see where the current value is: cat value
I am next going to see whether or not it is possible to control my pi via my Macbook Pro with the El Capitan OS.
