Basic Raspberry PI Projects
How to blink an LED using Raspberry Pi and the Python Software? 1. Gather all electronics materials and make the led-resistor circuit first. Connection: Pin 18 > Led > Resistor > Ground. 2. Open the Raspbian icon menu, select programming and choose Python Idle 3. Once python is open, click File > New File 4. Copy and paste the code (to turn on/off led): import RPi.GPIO as GPIO import time GPIO.setmode(GPIO.BCM) GPIO.setwarnings(False) GPIO.setup(18,GPIO.OUT) #print "Led ON" GPIO.output(18,GPIO.HIGH) time.sleep(10) #print "Led OFF" GPIO.output(18,GPIO.LOW) 5. OR, copy and paste this code (to blink the led): import RPi.GPIO as GPIO import time GPIO.setmode(GPIO.BCM) GPIO.setwarnings(False) GPIO.setup(18,GPIO.OUT) while True: GPIO.output(18, True) # Turn on pin 18 time.sleep(1) # Delay GPIO.output(18, False) ...
