On my Raspberry Pi B+ I have a standard program to blink a LED. I run it using the terminal command
python blinky.py, and when I do, the LED lights up, but does not blink, as it should. I then cancel the running command using ctrl+c, but the LED remains on.
Thoughts? Python code is below.
import RPi.GPIO as GPIO import time # blinking function def blink(pin): GPIO.output(pin,GPIO.HIGH) time.sleep(100) GPIO.output(pin,GPIO.LOW) time.sleep(100) return # to use Raspberry Pi board pin numbers GPIO.setmode(GPIO.BOARD) # set up GPIO output channel GPIO.setup(11, GPIO.OUT) # blink GPIO17 50 times for i in range(0,550): blink(11) GPIO.cleanup()
Edit: The circuit I used connected pin 9 as ground to a resistor to reduce the voltage to a palatable amount to the LED, then through the LED to GPIO pin 11.
