Kuv tau xaiv "Xov Tooj Hu" thiab tau teeb xim rau leej twg "C: YOG", Tom qab ntawd nws yuav nug koj kom xaiv txoj haujlwm, nyem "Ua Haujlwm Tshiab" thiab npe nws basted ntawm koj qhov kev ua. Kuv yuav hu nws "Hu Xov Tooj" tom qab ntawd nyem qhov txuas ntxiv thiab saib rau "HTTP Lub Taub Hau" thiab teeb tsa Tus Neeg rau zaub mov: Chaw nres nkoj rau koj_raspberry_pi_IP tom qab ntawd koj tuaj yeem teeb tsa xim nrog "/? Xim = Ntsuab" lossis koj tuaj yeem tsim peb yuav ua qhov no hauv cov kauj ruam tom ntej. Tom qab ntawd nyem rov qab thiab rov ua dua.

IFTTT

ua ntej tau txais ifttt thiab tsim ib qho tshiab applet Xaiv ib qho txhais (Kuv xaiv khawm) thiab tom qab ntawd rau qhov kev xaiv xaiv tus tsim channel thiab hais kom ua qhov peb thov tom qab ntawd rau qhov url nkag rau YOUR_PUBLIC_PI/? xim = LightBlue yog tias koj tsis paub koj cov pej xeem ip tsuas yog nkag mus "Kuv Ip" hauv google. Tom qab ntawd rau txoj hauv kev nkag mus HEAD ces nyem "Tsim Ua" tam sim no thaum koj qhov kev txiav txim tshwm sim ifttt thov kom koj tus pi hloov xim.

Lwm Cov Kev Pabcuam

Koj tseem tuaj yeem txuas lwm cov kev pabcuam uas ua rau HTTP HEAD lossis GET thov.

Kauj Ruam 15: Tsim Kev Cai Zoo

Hauv Main.py ntxiv cov lus hais qhia ntshuam, nyob hauv ntshuam os nkag

lub sij hawm ntshuam

kuj ua ntej peb tsim cov txiaj ntsig peb xav tau ntxiv qhov sib txawv hauv qab GreenBeforeEffect ntxiv

CanChangeColour = Tseeb

ces hloov yog thov.args.get ('Xim'):

rau

yog thov.args.get ('Xim') thiab CanChangeColour:

ntu tsuas yog nyob hauv qab render_template ('Main.html') ntxiv

@app.route ('/Effect', cov hau kev = ['GET'])

def nyhuv ():

Tom qab ntawd teeb tsa qhov sib txawv rau ntiaj teb

x = 0 os

Ntiaj teb RedColourCode thoob ntiaj teb BlueColourCode thoob ntiaj teb GreenColourCode thoob ntiaj teb RedBeforeEffect ntiaj teb BlueBeforeEffect ntiaj teb GreenBeforeEffect

tam sim no cia tsim peb thawj cov nyhuv

yog thov.args.get ('Hu'):

RedBeforeEffect = RedColourCode BlueBeforeEffect = BlueColourCode GreenBeforeEffect = GreenColourCode FadeTORGB (0, 0, 0) time.sleep (2)

Qhov kev txiav txim no yuav khiav thaum tus pi tau txais qhov kev thov zoo li "/? Effect = Call" thiab yuav khaws cov xim tam sim no yog li peb tuaj yeem hu nws rov qab, Peb tom qab ntawd ua rau cov hlua coj dub thiab tos kom txog thaum nws tshwm sim.

Tam sim no peb tab tom yuav ua rau cov xim ploj los ntawm dub mus rau ntsuab tom qab ntawd mus rau dub dua thiab kuv xav ua qhov no tsib zaug

thaum x <= 5: FadeTORGB (0, 255, 0) x += 1 lub sijhawm., BlueBeforeEffect, GreenBeforeEffect)

Qhov no yuav suav txog tsib tab sis txhua lub sijhawm nws yuav ploj mus rau ntsuab thiab tom qab ntawd tos ib pliag thiab mus rau xim dub. Tom qab ntawv yam uas ua tiav nws yuav hloov xim rov rau qhov koj tau ua ntej hloov pauv.

Tam sim no peb tsuas yog tsim cov lus teb.
