Connecting up to three 5v motion sensors on the raspberry pi for a project and I'm pretty new to python. I've successfully coded one motion sensor which lights up an LED and makes a buzzer sound when motion detected. How would I code multiple sensors that then light up different LEDs?
# Motion detected with buzzer and LED
import RPi.GPIO as GPIO
import time
GPIO.setwarnings(False)
#Refer pins by their sequence number on the board
GPIO.setmode(GPIO.BCM)
#Read output from PIR motion sensor
GPIO.setup(18, GPIO.IN)
#LED output pin
GPIO.setup(3, GPIO.OUT)
while True:
inp = GPIO.input(18)
#When output from motion sensor is HIGH
if inp == 1:
print("Motion detected!!")
GPIO.output(3, 1) #Turn on LED & Buzzer
time.sleep(1)
#When output from motion sensor in LOW
elif inp == 0:
print("No motion, all okay.")
GPIO.output(3, 0) #Turn off LED & Buzzer
time.sleep(1)
time.sleep(0.1)
You should create different instances for your sensors, for instance
inp_a = GPIO.input(18)
inp_b = GPIO.input(1x)
and so on.
then you can check with
if inp_b == 1
You can implement multithreading as well
Also, note that your last line of code, after the while loop, will never be executed.
