I'm new to the Raspberry Pi and trying to get a handle on GPIO programming. I'm using examples in Raspberry Pi User Guide by Halfacree and Upton. I've set up the libraries, Pi and breadboard as indicated in the Guide. When I test by wiring the LED directly to the 3.3 V on the GPIO connector the LED lights.
This is the program I'm trying to execute:
import RPi.GPIO as GPIO
I inserted some print commands to be sure that the program was indeed stepping through the instructions. It was, but the LED did not blink. No error messages were generated.
