setup is RPI3 with on pin 4 i have a relay connected (sainsmart board)
Code: Select all
#!/bin/python import RPI.GPIO as GPIO import time GPIO.setmode(GPIO.BCM) GPIO.setwarnings(False) GPIO.setup(4, GPIO.out) try: while True: GPIO.output(4, GPIO.1) sleep(.2) GPIO.output(4, GPIO.0) except KeyboardInterrupt: GPIO.output(4, GPIO.1)
IndentationError: expected an indented block
What is wrong with my code?
Some code start with #!/bin/python
others with #!/usr/bin/python
what is the difference or best?
