Raspberry Pi Forums

I have a photogate code that its already working, it measures how long the signal gets cut, this is the code:

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BOARD)

GPIO.setup(11,GPIO.IN)

start = time.time()
stop = time.time()
gateState = False
mid = 0

try:
while True:
if (GPIO.input(11) != gateState):
gateState = not gateState

if (gateState == True):
start = time.time()
else:
stop = time.time()

if stop - start > 0.1:
print "Time: ", stop - start, "s"

except KeyboardInterrupt:
GPIO.cleanup()


Now I have a code to control two servo motor at the same time to open at a certain angle, this is the code:

import time
import pigpio

servos = [17,27] #GPIO number

gpio = pigpio.pi()
#pulsewidth can only set between 500-2500
try:
while True:

gpio.set_servo_pulsewidth(servos[0], 500) #servo 1 to 0 degree
print("Servo {} {} micro pulses".format(servos, 500))
time.sleep(2.5)
gpio.set_servo_pulsewidth(servos[1], 1500) #servo 2 to 90 degree
print("Servo {} {} micro pulses".format(servos, 1500))
time.sleep(2.5)
gpio.set_servo_pulsewidth(servos[0], 1500)
print("Servo {} {} micro pulses".format(servos, 1500))
time.sleep(2.5)
gpio.set_servo_pulsewidth(servos[1], 500)
print("Servo {} {} micro pulses".format(servos, 500))
time.sleep(2.5)

# switch all servos off
except KeyboardInterrupt:
for s in servos:

gpio.set_servo_pulsewidth(s, 0);

gpio.stop()


Now I want to combine both codes together so depending on the time of the signal being cut it would activate one of the servo motors, our project its a ramp that we would slide three different sizes of boxes measuring it with the time delay on the photogate and then it will send the box to the corresponding gate. I included a picture of the ramp that would have the photogate circuit in the top, thanks for your help.
