I'm quite new to the Raspberry world, and I cannot figure out what's not working on my tiny test project on my B+.
I connected a red LED to the 3v3 (pin#1) and a resistor to the ground (pin#6), and the light is on.
Then I turn a GPIO on with this command (I use WiringPi) :
gpio mode 0 out gpio write 0 1 gpio read 0 //returns 1
But if I connect a yellow LED to the GPIO 0(pin#11) and a resistor to the ground (pin#6), the light is off.
I tried also with others GPIO and no success either.
What am I doing wrong?
