Cobbler Wrong GPIO Numbers?
Hello, I'm a total beginner so maybe I'm doing something wrong...
I just recieved my Raspberry Pi Starter Kit with your Pi Cobbler (Pre-assembled).
For testing, I made a simple circuit with a LED and Resistor. This works nicely when I connect to the 3.3v and GND.
I wanted to control this with Python so I connected the GND cable to #18 (From Tutorials on the web) and tried to turn it on using GPIO.setup(18, GPIO.OUT) / GPIO.output(18, True). This didn't do anything, the LED wouldn't light up.
The Only way I can get it to work is when I plug the 3.3V cable into #24 (!). Like that I can control the LED with #18 in Python.
What's wrong here?
