Kauj Ruam 2: 3D Luam Case

Cov ntaub ntawv tau luam tawm ntawm Creality Ender 3 Tshuab Luam Ntawv uas siv peb daim ntawv sib cais.

1. Chav Nyob
2. Hau
3. Cov ntaub ntawv sab hauv

Cov ntawv luam tawm thiab cov lus qhia rau kev luam ntawv tuaj yeem pom ntawm no ntawm Thingiverse.

Kauj Ruam 3: Tsim thiab Xeem Circuit

Yuav ua li cas Circuit Court Ua Haujlwm

Arduino Nano tau npaj rau kev sib tham nrog Servo thiab Fingerprint Sensor. Lub Fingerprint sensor tau npaj ua ntej nrog lub tsev qiv ntawv Fingerprints uas koj xav kom tuaj yeem qhib lub Qhov Chaw Muag Khoom.

Lub qhov rooj xauv lub qhov rooj yog siv los ua lub tshuab xauv thaum lub hau kaw. Ib qho infrared sensor siv los tshuaj xyuas tias lub qhov rooj raug kaw.

Kuv tau siv WS2182 LEDs uas muaj IC built-in uas ua rau lawv tuaj yeem hais los ntawm Arduino siv peb lub xov tooj sib cais txawm li cas los xij ntau yam xim thiab ci xim tuaj yeem tsim los ntawm kev xa lus txib mus rau LED. Qhov no tau ua tiav los ntawm lub tsev qiv ntawv tshwj xeeb uas thauj mus rau Arduino IDE tau them rau hauv ntu kev xeem.

Tsim thiab Xeem Fingerprint Reader Circuit

Sib dhos lub Circuit Court ntawm Breadboard tom qab daim duab qhia chaw muab.

Cov Tsev Qiv Ntawv hauv qab no yuav tsum tau rub tawm thiab ntxiv rau Arduino IDE ua ntej rub lub program rau hauv Arduino Nano

FastLED.h

Adafruit_Fingerprint.h

Thauj lub Adafruit_enroll_fingerprints. INO cov ntaub ntawv thiab ua raws li cov lus qhia kom tso npe 10 tus ntiv tes tshiab hauv thawj 10 qhov chaw. Kuv cov lus qhia yog siv ob tus ntiv tes sib cais 5 zaug kom koj tuaj yeem paub tseeb tias muaj kev ntseeg tau ntawm kev qhib lub tsev.

Kuaj Chav Nyob

Thauj cov ntawv Biometric_Personal_Diary. INO thiab thauj cov cai rau hauv Arduino Nano. Kuaj lub qhov rooj xauv lub qhov rooj yog ua haujlwm lub ntsuas phoo thaum lub tshuab ntsuas hluav taws xob raug thaiv simulating lub hau raug kaw. Ntawm lub zog tuaj xiav LED pib ua ntu zus tshwm sim. Lub Servo yuav tsum ruaj khov thiab tsis txhob tham tom qab pib lub zog.

Thaum siv lub zog, nrog Infrared Sensor thaiv lub teeb ntsuab nyob rau hauv Finger Print Sensor yuav tsum qhib. Txog tam sim no, chav tsev tau npaj nyeem ntiv tes. Muab koj tus lej scanned yav dhau los thiab kaw ntiv tes tso rau ntawm lub ntsuas thiab tuav kom txog thaum LEDs qhia tias nyeem tau tiav. Yog tias LEDs liab ces tus ntiv tes tsis raug lees paub thiab chav tsev yuav sim nyeem txuas ntxiv mus. Yog tias LEDs ntsuab tom qab ntawd cov ntiv tes tau lees paub thiab koj yuav tsum pom Servo ua haujlwm. (Saib daim vis dis aus ntawm qhov ntsuas saum toj no)

Kauj Ruam 4: Sib sau ua ke ntawm Circuit thiab Base Mechanism

Arduino Nano Cov

Mount Arduino Nano ntawm ib daim ntawm Vero Board txiav kom loj kom haum rau hauv kab noj hniav raws li cov duab. Ua raws daim duab qhia chaw thiab cov duab kom ntxiv cov resister thiab txuas lub zog siv cov xov hlau txuas.

Finger Print Sensor

Siv cov hlua txuas thiab cua sov ua tib zoo muab cov xov txuas txuas ntxiv ntawm Finger Print Sensor kom ntseeg tau tias cov xov hlau tuaj yeem mus txog Arduino. Teem lub thaiv los ntawm lub hauv paus qhov kom zoo li ib daim duab. Muab Finger Print Sensor tso rau hauv lub hauv paus raws li cov duab muab.

Infra Liab Sensor

Ua raws li kev sib txuas los txuas IR Sensor thiab LED thiab ix lawv rau hauv 3D luam tawm LED sensor mount muab los siv cov kua nplaum kub. Qhia cov xov hlau mus rau Arduino kom ntseeg tau tias lawv haum haum rau hauv chav tsev thiab tuaj yeem ncav cuag Arduino. Txheeb xyuas tias qhov sib txawv ntawm Infra Red LED thiab Sensor yuav haum rau lub qhov rooj kaw tab muab hauv 3D luam ntawv raws li cov duab. Qhov no yog siv txhawm rau txhawm rau nqaj thaum lub qhov muag Chaw muag mis nyuj kaw.

Chav tsev Servo

Mount lub Servo hauv Servo Mount Bracket muab hauv 3d Luam. Ua tib zoo nteg cov hlua sab hauv hauv qab kom lawv tuaj yeem ncav cuag Arduino. Siv daim ntawv kaw daim ntawv txuas rau Servo Arm rau lub tshuab xauv thiab muab tso rau hauv lub hauv paus. Tawm ntawm Servo zaum hauv txoj haujlwm yog li nws tuaj yeem ua raws thiab kho thaum qhov kev sim zaum kawg thiab sib dhos tshwm sim.

Rechargeable Power Bank

Xyuas kom Powerbank koj siv yuav haum rau hauv qhov chaw muab thiab tseem tuaj yeem nkag mus rau USB them chaw nres nkoj ntawm Powerbank. Teem lub USB chaw nres nkoj mus rau hauv ntej ntawm rooj plaub thiab siv lub laum los tsim lub qhov tsim nyog rau them lub hom phiaj (Saib daim duab)

Hloov

Txuas lub zog thiab thawb khawm hloov mus rau cov xaim txuas thiab siv cov kua nplaum epoxy txhawm rau kho cov no rau hauv lub qhov uas tau muab hauv lub hauv paus.

Xyuas kom Arduino lub rooj tsavxwm thiab cov kab hluav taws xob yuav haum rau hauv kab noj hniav los ntawm kev ua kom zoo nyob ntawm cov xov hlau thiab txiav qhov ntev ua ntej yuav siv mus rau ntawm Pawg Thawj Tswj Xyuas Vero.

Kuaj chav tsev

Fais fab ntawm chav tsev siv qhov hloov pauv thiab sim ua haujlwm yooj yim ntawm chav tsev.

Kauj Ruam 5: Muab Nws Txhua Qhov Ua Ke

Thaum chav ntsuas tau ntsuas qhov kev hloov kho zaum kawg yuav tsum tau ua kom ntseeg tau tias ua haujlwm tau zoo. Txuas lub hau rau lub hauv paus thiab tshawb xyuas lub qhov rooj qhib thiab kaw dawb.

Servo Lock Mechanism Alignment

Saib xyuas txoj haujlwm ntawm Servo hauv daim vis dis aus rau kaw thiab qhib lub qhov rooj. Sib sau ua ke lub qhov rooj thiab kho lub caj npab servo kom ntseeg tau tias lub qhov rooj kaw qhov rooj tsis koom nrog. Muab lub qhov rooj xauv rau hauv lub hauv paus los ntsuas qhov sib dhos ntawm lub tshuab xauv. Fais fab ntawm chav tsev thiab kuaj xyuas tias Lub Qhov Rooj Qhov Rooj koom nrog raug thiab taug kev dawb. Cov cuab yeej ntsuas tau muaj cov lus qhia uas pab ua kom ntseeg tau lub qhov rooj kaw qhov rooj kom tsis txhob cuam tshuam. Thaum raug lawm ces kub kua nplaum rau Servo thiab Sensor chav nyob hauv qhov chaw.

Mount Qhov Rooj Xauv thiab Qhov Rooj Kaw Tabs

Nrog cov hlua txuas kom zoo tso qhov L lub hau npog rau qhov tsis pom kev Nano, Servo, thiab thaiv. Thaum txaus siab tso lub Qhov Rooj Xauv Tab thiab Lub Qhov Rooj Kaw Tab rau hauv lub hauv paus qhov qhov thiab tshawb xyuas lub xauv tshuab ua haujlwm kom qhib thiab kaw.

Thaum ua raws thiab kuaj pom muab cov kua nplaum epoxy tso rau ntawm cov tab thiab tom qab ntawd maj mam kaw lub hau thiab tawm mus li ob peb teev kom qhuav. Thaum kawg sim ua haujlwm ntawm chav tsev ua ntej ntxiv koj Chaw muag mis nyuj, Cwj mem thiab lwm yam khoom koj xav tau kev nyab xeeb los ntawm kev maj mam ntiv tes thiab txhais tes.

Kuv vam tias koj txaus siab rau kev tsim kho thiab siv cov cuab yeej me me txias no !!
