PAGING SYSTEM FOR INPATIENTS
A wifi service to patient’s devices can serve a button to paging nursing staff in their station with a push of a button on the served page, which triggers a physical pin in raspberry pi which can be observed as a LED or a buzzer.

PHP to control GPIO pins (LED, buzzer…)
This to allow patients in different rooms ask for help by pressing the appropriate button on their served web page.
Check wiringpi is installed:
Gpio -v
Gpio readall
Test using shell:
Gpio -g write 17 1
Sudo usermod -a -G gpio www-data // add php user to group gpio
Set permission by:
Sudo visudo
Add www-data ALL=NOPASSWD: ALL
Code:
<form action=”php.php”>
<input type=”submit” name=”ON” value=”Turn On” />
</form>

NOTIFYING VIA LOBBY STATION
Office visit notification can be automated by asking the customer to press a button and get notified in your office. This can be done by a push button attached to Raspberry pi server located in the lobby, when pushed down, the office pi buzzer is turned on via the server wifi that the latter is connected to.
The client pi remote GPIO settings needs to be enabled via raspi-config
import RPi.GPIO as GPIO
from time import sleep
from gpiozero import LED
from gpiozero.pins.pigpio import PiGPIOFactory
factory = PiGPIOFactory(host='192.168.215.201')
red = LED(22,pin_factory=factory)
buz = LED(23,pin_factory=factory)
#Set warnings off (optional)
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BOARD)
#Set Button and LED pins
Button = 32
led = 22
#Setup Button and LED
GPIO.setup(Button,GPIO.IN,pull_up_down=GPIO.PUD_UP)
GPIO.setup(led,GPIO.OUT)
#flag = 0
while True:
button_state = GPIO.input(Button)
print(button_state)
if button_state == 0:
GPIO.output(led,GPIO.HIGH)
red.on()
buz.on()
else:
GPIO.output(led,GPIO.LOW)
red.off()
buz.off()
sleep(1)
