nfc raspberrypi felica servo: turn on/off light of a room

Turn the servo only for your suica.

`turn_servo.py`


import nfc
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BOARD)
servo_pin = 3
GPIO.setup(servo_pin, GPIO.OUT)
servo = GPIO.PWM(servo_pin, 50)
my_id = '01010501b00ac30b'

def connected (tag):
    return
    #time.sleep(1)
    
clf = nfc.ContactlessFrontend('usb')
servo.start(0)
status = 'opened'

while True:
    print('waiting...')
    tag = clf.connect(rdwr={'on-connect':connected})
    felica_id = str(tag.idm).encode("hex")
    if (my_id == felica_id):
        print('matched!!')
        #servo.start(0)
        if (status == 'opened'):
            #open the door
            servo.ChangeDutyCycle(2.0)
            status = 'closed'
        elif(status == 'closed'):
            #close the door
            servo.ChangeDutyCycle(5.0)
            status = 'opened'
        #servo.stop()
    else:
        print('invalid id!!')

    print(status)
    print('scaned')
    time.sleep(0.2)

servo.stop()
GPIO.cleanup()

Turn on / off the electricity in the room with the servo. I really wanted to open and close the door key, but I gave up because the key was unexpectedly hard. Moreover, Gamte implementation. Well.

With the KRS servo, you can also get the angle ...
