Kauj Ruam 9: Kev Ua Haujlwm - Loj Dome Push Button

Lub khawm loj dome thawb yog lub khawm puag ncig loj - nrog ib ncig 100mm tawm txoj kab uas hla nrog lub me me LED. Nws hais tias nws ua haujlwm ntawm 12V, tab sis 3.3v ntawm Raspberry PI txaus los teeb nws

Siv cov txheej txheem ntsuas

Cov cai:

los ntawm RPi ntshuam GPIO

takeButton = 17 ledButton = 27 GPIO.setmode (GPIO. BCM) GPIO.setup (takeButton, GPIO. IN, GPIO. PUD_UP) GPIO.setup (coj Kev thaiv kev ua haujlwm GPIO.wait_for_edge (siv, Button, GPIO. FALLING) luam tawm ("Nias Nias") GPIO.output (ledButton, False) GPIO.cleanup ()

Qee qhov piav qhia ntawm txoj cai Ib qho ntawm cov ntawv tau txais txiaj ntsig los ntawm GPIOS yog los ntawm kev cuam tshuam (lwm qhov yog kev xaiv tsa) - kev txheeb xyuas ntug.

Ntug ntug yog lub npe ntawm kev hloov pauv los ntawm HIGH mus rau LOW (ntog ntug) lossis LOW mus rau HIGH (nce ntug). Thaum tus lej PIN tsis txuas nrog ib yam dab tsi, ib qho nyeem yuav tsis tau txhais. Ib qho kev daws teeb meem yog kom muaj kev rub tawm/nqis resistor hauv tus lej PIN. Raspberry PI tso cai rau teeb tsa rub tawm/nqis resistors los ntawm software.

Kab

GPIO.setup (takeButton, GPIO. IN, GPIO. PUD_UP)

teeb tsa tus lej PIN kom ua li ntawd - rub tawm

Vim li cas rub? Zoo, lub khawm loj dome khawm muaj 2 tus lej PIN - thawb kom tawg lossis thawb kom ua (ib yam li cov khawm me me uas feem ntau tuaj nrog Arduino/Raspberry PI cov khoom siv). Kuv tau txuas nws mus rau "thawb ua" PIN ntawm lub pob. Thaum nias, lub kaw lus kaw thiab hluav taws xob hla (ib txwm qhib).

Kab

GPIO.wait_for_edge (takeButton, GPIO. FALLING)

yuav tos (tshem tawm qhov ua tiav ntawm tsab ntawv) kom txog thaum nws pom qhov poob ntawm tus lej PIN - tso lub pob yuav txiav cov hluav taws xob ntws thiab tus lej PIN yuav los ntawm 3.3v txog 0v

LED PIN tsuas yog txhawm rau teeb lub LED ntawm lub pob

Xav paub ntau ntxiv txog kev thawb hloov los ntawm Arduino Tutorials, Wikipedia ntawm kev thawb los ua lossis thawb kom tawg thiab GPIO cuam tshuam

Tam sim no, cia ua ke lub laub khawm nrog lub koob yees duab - thaij duab tsuas yog thaum lub pob nyem

ntshuam picamera los ntawm lub sijhawm ntshuam pw los ntawm RPi ntshuam GPIO los ntawm PIL ntshuam duab # LUS CEEB TOOM: Nov yog dab tsi yuav yog lub khawm rho tawm hauv txoj haujlwm tseem ceeb # Kuv tsuas yog siv nws ntawm no kom pom tseeb hauv qhov yees duab takeButton = 24 ledCancel = 5 GPIO.setmode (GPIO.

Kev piav me ntsis

Nws pib lub koob yees duab saib ua ntej thiab tos nyob ntawd kom txog thaum lub pob nyem. Tom qab lub pob nyem, lub teeb ci LED thiab suav rov pib dua. Thaum mus txog qhov kawg, daim duab raug coj thiab LED tau muab tua

Kauj ruam 10: Tshaj tawm rau Twitter

Tam sim no, peb tab tom siv Python thiab tshaj tawm tweet!:) Koj yuav xav tau daim duab los tshaj tawm - xaiv ntse ntsuav.

Ua ntej, peb yuav tsum tau txais twitter API thiab rau qhov uas peb xav tau los tsim APP. Mus rau https://apps.twitter.com tsim daim ntawv thov tshiab.

Koj yuav tsum tau thov rau tus account tsim tawm - sau qee cov lus nug thiab paub meej tias koj tus email chaw nyob. Tom qab ntawd, koj yuav tuaj yeem tsim APP tshiab.

Tom qab tsim lub APP, mus rau Cov Keys thiab Tokens thiab Tsim Kev Nkag Nkag Nkag thiab nkag mus rau Token Secret. Ib lub qhov rai yuav pom nrog Cov YOOJ YIM TSHIAB nkaus xwb - Luam cov no thiab khaws lawv rau tom qab.

Siv cov cai hauv qab no los xa daim duab rau koj tus account twitter. Tsis txhob hnov qab sau:

• tus neeg siv_key
• neeg_secret
• access_token
• access_token_secret

twitter cov lus yog cov ntawv xa hauv tweet.

jpg_foto_to_send yog daim duab uas yuav muab txuas rau hauv tweet. Thov muaj qee daim duab nyob hauv phau ntawv teev npe ib yam li Python tsab ntawv thiab hloov lub npe hauv txoj cai.

Kauj Ruam 12: Txuas kab

Cov xov hlau tsuas yog txuas lub Dome Loj Push khawm mus rau Raspberry PI.

Tsuas yog ua raws Fritzing Schematic.

Cov kev sib txuas yog:

ConnectionRPI GPIO PIN GND Green Push ButtonGND (#3) GND Yellow Push ButtonGND (#9) GND Blue Push ButtonGND (#39) Coj Duab (Blue Push Button "Push to make") 17 (BCM) Tshaj Tawm rau Social Networks (Green Push Khawm "Push to make") 23 (BCM) Cancel (Yellow Push Button "Push to make") 24 (BCM) Blue Push button LED27 (BCM) Green Push button LED22 (BCM) Yellow Push button LED5 (BCM)

Cov cua sov kuj tseem yog xim xim

• Dub yog GND kev sib txuas
• Daj yog "thawb kom" sib txuas
• Xiav yog LED sib txuas

GPIO. BCM tus lej vs GPIO. BOARD kev sib txuas

Txij li thaum kuv kev sib txuas yog BCM, Kuv xav tias tam sim no yog lub sijhawm zoo los tham txog nws thiab qhov sib txawv ntawm BCM thiab BOARD.

Qhov sib txawv tseem ceeb yog koj xa mus rau GPIO PINs li cas, uas nyob rau hauv lem yuav tsav koj li kev sib txuas. GPIO.board yuav xa tus lej PIN los ntawm tus lej luam tawm ntawm txhua qhov txheej txheem GPIO hauv internet.

GPIO. BCM hais txog tus lej PIN raws li Broadcom SOC pom lawv. Qhov no zoo li yuav hloov pauv qhov tshiab ntawm Raspberry PI.

Ntawm tus pinout.xyz qhov chaw, cov lej lej yog tus uas nyob ib sab ntawm tus pin thiab BCM tau hais rov zoo li ntawd - BCM X (qhov twg X yog tus lej)

Kauj ruam 13: MagicBox

Cov lej txuas nrog rau cov kauj ruam no yog qhov kawg.

Koj tuaj yeem khiav nws ntawm raspberry PI khau raj, tsis tas yuav xav tau tus ID nkag mus. Txhawm rau ua qhov ntawd, tsuas yog tsim cov ntawv me me hauv cov npe uas koj tau tso cai - hloov txoj hauv kev raws li

#!/bin/tsoo

cd/tsev/pi/magicbox nab hab sej MagicBox.py

Ua kom nws executable

chmod +x start_magicbox.sh

Tam sim no, hu nws hauv /etc/rc.local, tsuas yog ua ntej qhov kev tawm 0 instuction

sudo vi /etc/rc.local

/home/pi/magicbox/start_magicbox.sh &

txuag thiab tawm mus.

Tam sim no, nrog txhua qhov rov pib dua, Python program yuav ua tiav
