Nov yog cov ntawv ntsuas cov laj thawj rau Raspberry pi, nrog rau qhov no koj tuaj yeem tshawb xyuas yog tias koj (tus kheej tsim) logic Circuit ua haujlwm.
Tsab ntawv no tseem tuaj yeem siv los ntsuas kev xa tawm.
CEEB TOOM:
Raspberry pi tsis txhawb nqa 5v GPIO cov tswv yim, yog li yog tias koj qhov hluav taws xob tso tawm 5V, koj yuav tsum tau txais nws mus rau 3V lossis qis dua (1.6V zoo li ua haujlwm ib yam nkaus), koj tuaj yeem ua qhov no nrog qhov faib hluav taws xob yooj yim.
Khoom siv
Rau Cov Lus Qhia no, koj yuav xav tau:
1 internet kab
1 Raspberry pi, nrog SD-card thiab Raspbian OS.
5 Cov xov hlau uas tuaj yeem txuas rau tus pin
1 khob cij
1 lub zog txuas rau koj Raspberry pi (duh!)
kuj koj yuav xav tau lub khoos phis tawj uas muaj chaw nres nkoj internet, thiab muaj lub davhlau ya nyob twg (MobaXterm)
thiab ntawm chav kawm lossis cov khoom koj xav sim.
(xaiv tau) 1 qhov faib hluav taws xob nrog piv R1: R2 = 1: 1 (kuv siv 2 200 Ohm resistors thaum xav tau)
Kauj Ruam 1: Tau Tsab Ntawv ntawm Koj Raspberry Pi
Zoo, yog tias koj xav pib koj yuav tsum muaj tsab ntawv, yog li ntawm no nws yog, koj tuaj yeem rub nws los ntawm Google Drive.
Nrog MobaXterm koj tuaj yeem tso cov ntawv hauv qhov chaw uas koj xav tau ntawm koj RPi.
yog tias koj xav ntaus nws hauv cov ntawv manually, kuj tseem muaj cov ntawv nyeem uas koj tuaj yeem luam tawm.
Kauj Ruam 2: Txuas Koj Tester
Yog lawm, kom tau txais txiaj ntsig koj yuav xav tau txuas koj lub tester mus rau yam khoom los sim.
Vim tias qhov no nyuaj dhau los piav nrog cov ntawv xwb, kuv tau txuas ob daim duab, ib qho nrog RPi pinout, thiab ib qho nrog 'kab duab kab' lossis qee yam.
Ntawm daim duab koj yuav pom Voltage Divider, uas koj yuav tsum siv thaum koj tab tom ntsuas 5v tso tawm rooj laj kab.
Tsis tas li muaj cov kab hluav taws xob txuas rau txhua qhov rooj logic (tsis txwv rau THIAB), thiab rau kev xa tawm.
Kuv vam tias cov duab no zoo txaus los piav rau koj yuav ua li cas txuas txhua yam.
Kauj Ruam 3: Xeem
Tom qab ua tiav qib 1 thiab 2, thaum kawg koj tuaj yeem xeem cov ntawv no, thiab tus ntsuas.
Txhawm rau khiav tsab ntawv, mus rau phau ntawv teev npe qhov chaw nyob ntawm tsab ntawv, thiab tom qab ntawd khiav nws los ntawm kev ntaus: python3 LOGIC_TESTER.py
(koj ua txhua yam no hauv koj li Raspberry pi lub davhlau ya nyob twg)
tom qab ntaus tus lej qhia saum toj no, koj tsuas yog yuav tsum ntaus tus lej 1 lossis 2, thiab ntaus nkag, nyob ntawm seb koj xav kom tsab ntawv ua dab tsi.
Kauj Ruam 4: Cov txiaj ntsig
Nrog koj zoo siab: tam sim no koj muaj thawj qhov txiaj ntsig los ntawm tus ntsuas, saum toj no yog qee qhov piv txwv ntawm cov txiaj ntsig
Tus ntsuas ntsuas ua ntej sau cov khoom siv los ntawm lub qhov rooj logic/relay, thiab tom qab ntawd khaws cov khoom tso tawm, tom qab ntawd nws yuav sib piv cov txiaj ntsig mus rau cov lus tseeb ntawm txhua lub rooj logic uas twb muaj lawm.
Yog tias cov txiaj ntsig tau zoo ib yam li qee lub rooj vag logic, nws yuav tso tawm lub npe ntawm lub rooj vag uas koj tau sim.
yog tias cov txiaj ntsig tsis sib npaug ntawm ib qho ntawm cov lus tseeb, koj lub rooj vag logic yuav tawg, lossis kev sib txuas tsis zoo.
muaj kev lom zem siv lub tester, thiab kuv vam tias koj pom qhov Kev Qhia Qhia no muaj txiaj ntsig.
