Code for the head lights.
#!/usr/bin/env python # Example for RC timing reading for Raspberry Pi # Must be used with GPIO 0.3.1a or later - earlier verions # are not fast enough! import RPi.GPIO as GPIO, time, os #referance name and gpio pin number HLED1 = 22 HLED2 = 24 sensor = 26 GPIO.setmode(GPIO.BOARD) GPIO.setwarnings(False) #Remember to setup the GPIO pin as input or output GPIO.setup(HLED1, GPIO.OUT) GPIO.setup(HLED2, GPIO.OUT) DEBUG = 1 GPIO.setmode(GPIO.BOARD) runningLights = (True) def RCtime (RCpin): reading = 0 GPIO.setup(RCpin, GPIO.OUT) GPIO.output(RCpin, GPIO.LOW) time.sleep(1.0) GPIO.setup(RCpin, GPIO.IN) # This takes about 1 millisecond per loop cycle while (GPIO.input(RCpin) == GPIO.LOW): reading += 1 return reading print ("Light program running!!!") while (runningLights == True): lightSensor = RCtime(sensor) #print lightSensor if ( lightSensor > 400): GPIO.output(HLED1,1) GPIO.output(HLED2,1) elif ( lightSensor < 400): GPIO.output(HLED1,0) GPIO.output(HLED2,0) GPIO.cleanup()
This code was adapted from the tutorial from Adafruit . The only change I have made is setting up the 2 LED`s (HLED1 and HLED2 ) and added an IF statement . The IF statement switch`s on the led`s if the light drops below 400 and of if it`s over 400. I got this figure by hours of experimentation by switching the bedroom light on and off. The print statement is there just so I know the program is running correctly. Hopefully in the future I will ingrate this code with the main code.
