This article mainly explains "how to use Python to create an intelligent voice alarm clock for girlfriend". The explanation content in this article is simple and clear, easy to learn and understand. Please follow the idea of Xiaobian and go deep into it slowly to study and learn "how to use Python to create an intelligent voice alarm clock for girlfriend" together!

preface

Recently, I learned some technologies related to the Internet of Things. I was a little impulsive and thought about what I could do. I happened to have heard some rumors about Raspberry Pi before, so I wanted to make a smart alarm clock.

It should be noted that before reading this article, you should at least be a program ape who can install the operating system, understand Linux, know some Python, and most importantly, you have to have a girlfriend. Of course, it doesn't matter, I believe that after reading this article, you also tried to make such an alarm clock, maybe…

List of hardware and software

Card reader and SD card (for system installation)

One speaker, preferably 3.5mm

SSH connectivity tools (SecureCRT, Xshell)

Broadband, router (this should be home)

Raspberry Pi 3B + one with installed system (charger, CPU cooling fan, etc.)

Before we get started, let's show off this half-finished alarm clock:

encoding

A qualified programmer, although Java, I still want to use her-Python to develop.

The Raspberry Pi 3B + system is pre-installed with Python 3 by default. We only need to install some third-party dependencies. The following is the main code:

__author__="Xiaoqi"__blog__="www.example.com" import timeimport randomimport osimport pygameimport urllib. requestimport jsonfrom aip import AipSpeech """Raspberry Pi makes smart alarm clock pip 3 install pygamepi ip 3 install baidu-aip"""#Get weather def get_weather ():#Qingdao weather, 101120201 is the code of Qingdao area, please find url ='http://www.qingda.com//www.weather.com.cn/data/cityinfo/101120201.html' obj = urllib. request. urlopen (url) data_b = www.example.com () data_s = data_s b. decode ('utf-8') data_dict = json. loads (data_s) rt = data_dict ['weatherinfo '] weather =' Dear: It's time to get up, don't sleep, soon become a pig, hahaha, I miss you, do you miss me?

Code does not understand, it does not matter, to a clear flow chart:

timing

Of course, the alarm clock can not play itself, we also need to add a timed task script to achieve timed play.

Run crontab-e flag to edit cron table

no crontab for pi - using an empty oneSelect an editor. To change later, run 'select-editor'. 1. /bin/ed 2. /bin/nano
