Install a tact switch on the Raspberry Pi to make daily "Good morning Yosoro !!" tweets comfortable

Introduction

Everyone! Do you use "_Oha Yosoro !! __"? This is the first voice that motivates me to get up every morning. Maybe love live! I think I tweeted every morning before the Sunshine !! anime started. (Saturdays, Sundays, and holidays may not be convenient) You Watanabe is an angel. so cute.

environment

Python 2.7.11 Raspberry Pi2 B Some knowledge of electronic circuits

Wiring on the Raspberry Pi side

The tact switch also has a proper orientation, so let's check it.

It's messy, Explain after numbering the legs of the tact switch Bottom left: No. 1 Bottom right: No. 2

1. Connect 3.3V to No. 1
2. Attach a 1kΩ resistor to No. 2.
3. Extend from the right end of the resistor to GND
4. Connect to GPIO 9 from the left foot of the resistor (on the extension of No. 2) (Pin No. 21 on the Raspberry Pi side in the physical arrangement)

Source code

I'm pushing to BitBucket for the time being.

app.py

# coding: utf-8

import RPi.GPIO as GPIO
import tweepy
import time, signal, sys, random
from datetime import datetime

def handler(signum, frame):
    print('Signal handler called with signal: ' + str(signum))
    GPIO.cleanup()
    sys.exit(0)

signal.signal(signal.SIGINT, handler)

def tweet():
    CONSUMER_KEY = ''
    CONSUMER_SECRET = ''
    ACCESS_TOKEN = ''
    ACCESS_SECRET = ''

    auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)
    auth.set_access_token(ACCESS_TOKEN, ACCESS_SECRET)

    api = tweepy.API(auth)

    tweet_text = ''
    if random.randint(1, 7) == 7:
        tweet_text = u'Good morning John! !!'
    else:
        tweet_text = u'Good morning Yosoro! !!'

    api.update_status(tweet_text + '\n{0:%Y/%m/%d %H:%M:%S}'.format(datetime.now()) + u'Niyakashi got up')

GPIO.setmode(GPIO.BCM)
GPIO.setup(9, GPIO.IN)
before = 0

while True:
    now = GPIO.input(9)
    if before == 0 and now == 1:
        tweet()
    time.sleep(0.1)
    before = now

Get CONSUMER_KEY etc. in advance! Also, this time, in response to the request of enthusiastic followers, "_Oha John __" will appear with a probability of 1/6.

Execution result

First of all, I don't think that you will press the button continuously, but in consideration of the foolproof of duplicate tweets, I tried to tweet up to seconds.

Finally

I don't know which GPIO the infrared transmission LED was connected to at the time of this jumper code arrangement, I was sacrificed. If the shyness turns, it will be cured.
