2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Nyob zoo cov neeg. hnub no peb yuav ua lub qhov rooj wireless lossis hu lub tswb nrog thaj tsam ntawm 300 metres hauv ib qho chaw qhib piv rau 50 metres ntawm lub qhov rooj muag khoom lag luam uas peb nquag pom hauv khw.

Txoj haujlwm no tuaj yeem siv ua lub qhov rooj lossis ua lub xovtooj hu xovtooj wireless uas txuas txuas hu nrog tus hais lus los ntawm xov hlau yuav nyuaj.

Kuv tab tom qhia lub hauv paus ntsiab lus ua haujlwm ntawm lub khob cij, txawm hais tias koj tuaj yeem sib sau cov kev sib txuas kom haum hauv lub casing kom haum rau koj cov kev xav tau.

Kauj Ruam 1: Sau Cov Khoom

2. 10 xf1

Lwm yam

1. Leds x 2
2. 9v x 2 pin
3. Jumper xov hlau
4. Ib leeg tub ntxhais hlau
5. Tus nab npawb xov tooj x2
6. 8 ohm Hais lus x1
7. Tactile laub khawm x1
8. Breadboards x2

Kauj Ruam 2: Ua Tus Tshaj Tawm

Qhov yuav tsum tau rau Transmitter

1. 434MHZ Transmitter
2. HT12E IB IC
3. Tactile Push khawm
4. 1M ohm tiv thaiv
5. Cov qhob cij
6. Hlau

Txheej txheem

Tsuas yog ua raws cov duab ib qib zuj zus saum toj no tom qab nyem 3 daim duab ntxiv hauv qab daim duab sab xis.

HT12E yog tus lej encoding uas muab kev sib cuam tshuam nruab nrab ntawm tus qauv hloov pauv thiab Circuit Court. Nws muaj 4 cov ntaub ntawv hloov pauv tus pin uas txhais tau tias nws tuaj yeem hloov 4 khoom ntawm cov ntaub ntawv.

Nws kuj muaj 8 ntsis encryption feature uas txhais tau tias koj tuaj yeem siv qee yam zoo li THIS ntawm ob qho kev xa thiab tus txais thiab tsuas yog thaum ob qho kev hloov pauv teeb tsa cov ntaub ntawv yuav tau txais los ntawm tus txais. Txuas ib kawg ntawm qhov hloov pauv mus rau tus pin 1 txog 8 ntawm ob qho ICs (HT12E thiab HT12D) thiab lwm qhov kawg rau hauv av. Tam sim no tsis muaj tus xa tawm dua li ib qho uas muaj kev hloov pauv tib yam li tus txais tuaj yeem tswj tus txais.

Kauj Ruam 3: Ua Tus Txais

!!! Rau lub CIRCUIT yam tsis muaj MICROCONTROLLER LOOK NTAWV KAWG KAWG KAWG !

!!! Ob qho tib si ntawm IC yog lub luag haujlwm rau sab laug (Tus Qauv Txais) !

Txheej txheem

Tsuas yog ua raws ntu ntu ntawm cov duab ib qib zuj zus.

HT12D yog tus lej txiav txim siab uas muab kev sib cuam tshuam nruab nrab ntawm Tus Qauv Txais thiab lub Circuit Court. Nws muaj 4 cov ntaub ntawv hloov pauv tus pin uas txhais tau tias nws tuaj yeem hloov 4 khoom ntawm cov ntaub ntawv.

Nws kuj muaj 8 ntsis encryption feature uas txhais tau tias koj tuaj yeem siv qee yam zoo li THIS ntawm ob qho kev xa thiab tus txais thiab tsuas yog thaum ob qho kev hloov pauv teeb tsa cov ntaub ntawv yuav tau txais los ntawm tus txais. Txuas ib kawg ntawm qhov hloov pauv mus rau tus pin 1 txog 8 ntawm ob qho ICs (HT12E thiab HT12D) thiab lwm qhov kawg rau hauv av. Tam sim no tsis muaj tus xa tawm dua li ib qho uas muaj kev hloov pauv tib yam li tus txais tuaj yeem tswj tus txais.

Kauj Ruam 4: Xa Cov Cai

1. Rub tawm arduino software.
2. Rub tawm Digispark attiny tsav tsheb cov ntaub ntawv saum toj no yog tias koj yuav siv digispark usb attiny microcontroller lossis koj tuaj yeem hla qhov txheej txheem teeb tsa (cov kauj ruam 2, kauj ruam 3 thiab qib 4) ntawm cov tsav tsheb yog tias koj yuav siv nano.
3. Tam sim no nyem Cov Ntaub Ntawv> Nyiam thiab tom qab ntawv hauv kab ntawv ze rau hauv qab ntawm ib sab ntawm cov ntawv ntxiv tus thawj tswj hwm daim ntawv theej thiab muab qhov txuas no.
4. Mus rau Cov Cuab Yeej> Boards> Tus Thawj Saib Xyuas Lub Rooj thiab ntaus digistump thiab nyem thiab teeb tsa lub rooj tsavxwm.
5. Rub lub speaker.ino cov ntaub ntawv saum toj no thiab qhib nws.
6. Tam sim no tsuas yog txuas lub rooj tsavxwm thiab nyem upload. (Xub xub xub)

QHOV TSEEB INSTALL INSTRUCTIONS

Kauj ruam 5: Ua tiav

Tam sim no txhua yam koj yuav tsum tau ua yog txuas lub Roj Teeb. Txuas lub roj teeb raws li qhia hauv daim duab rau ob qho tib si xa thiab txais.

Kauj Ruam 6: Xeem

Koj ua tiav. Tam sim no nyem lub pob hauv lub tshuab xa hluav taws xob thiab hnov lub suab nrov nrov.

Yog tias nws tsis yog beeping kos cov kev sib txuas rau ib qho xoob thiab tom qab ntawd txheeb xyuas txhua qhov kev sib txuas raws li cov duab lossis koj tsuas tuaj yeem saib kuv cov vis dis aus NTAWV kom ua raws cov lus qhia yooj yim dua.

Koj tuaj yeem txawm ntsuas nws.

Kuv yog: --- meters.

Kauj Ruam 7: Koj Ua tiav

Koj tuaj yeem hloov qhov phiaj xwm phiajcim mus rau PCB kom ua kom nws nruj dua thiab tiv thaiv kom tsis txhob muaj kev sib txuas.

Kauj Ruam 8: Daim Duab Circuit Court rau Tswb Hluav Taws Xob

Kuv ua qhov no ua ntej tab sis

Pros

1. Pheej yig dua
2. Tsis muaj coding

Cons

1. Pw tsaug zog ntau dhau
2. Circuit loj heev.

Kauj ruam 9: Tsis txhob hnov qab Saib Kuv Youtube Video
