2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Peb tau txais peb lub tswv yim los ntawm peb tus kws qhia ntawv engineering - peb txhua tus xav tias nws yuav yog lub tswv yim zoo kom muaj lub tshuab muag khoom rau peb chav kawm thiab nws hais tias - "txias, ua ib qho". Nws tau muab tawm tias lub tshuab muag khoom yuav yog qhov haujlwm zoo tshaj plaws thiab thaum ua tiav yuav ua haujlwm raws li kev nrhiav nyiaj txiag rau peb txoj haujlwm engineering.

Nws hu ua $ 1 Vending Machine tsis yog vim nws raug nqi $ 1 los ua, tab sis tsuas yog vim tus neeg lees txais daim nqi yog tus qauv qub uas tsuas siv $ 1 nqi xwb:)

Kauj Ruam 1: Cov Qauv

Peb xav tau lub tshuab muag khoom uas yuav haum rau saum lub rooj thiab tsis siab dhau. Peb coj qhov ntev ntawm qhov dav ntawm lub rooj kom paub tseeb tias peb tsis muaj lub tshuab muag khoom dai ntawm lub rooj.

Kauj ruam 2: Casing

Peb ua peb lub thawv 19 ntiv dav los ntawm 17 ntiv tes ntev los ntawm 25 ntiv siab. Peb siv lub tshuab CNC txiav peb cov ntoo. Peb siv cov txheej txheem khov kho los tsim lub ntsej muag thiab tom qab ntawd hloov lawv mus rau kev kos cov hom ntaub ntawv rau peb CNC software. Peb txhuam cov ntug thiab tom qab ntawd ntswj lawv nrog 1 ¼ ". Peb txuas lub vaj huam sib luag pem hauv ntej nrog lub pob khawm thiab siv screws "cov ntsia hlau, yog li cov ntsia hlau yuav tsis hla mus rau lwm sab. Peb kuj siv Acrylic iav uas peb txiav rau lub txee thiab lub vaj huam sib luag pem hauv ntej.

Kauj ruam 3: Electronics

Arduino

Peb siv Arduino Mega 2560 Board. Peb kuj tseem siv Adafruit Motor Boards kom lawv tuaj yeem khiav cov cav ntoo stepper. Peb ntxiv cov pins rau cov adafruit kom lawv txuas mus rau ib leeg. Lawv tau muab lawv tso rau saum ib leeg. Txhua tus tuaj yeem khiav 2 lub cav. Tsis tas li, thov nco ntsoov tias lub jumper xav tau txuas nrog.

Cov Khoom Siv Hluav Taws Xob

Bestek ATX Fais fab siv siv lub adapter kom lub hwj chim muab rau. Tus adapter yog los ntawm sparkfun.com thiab muab ntau yam hluav taws xob.

Coils rau hauv Motors

Peb tau tsim cov qauv ua haujlwm kom tuav lub cav, rub lub kauj, thiab coj cov kauj raws lub txee. Peb tau ua tiav peb cov coils los ntawm ebay thiab txiav lawv mus rau qhov ntev. Peb kuj yuav tsum tau khoov 3 ntawm lawv txij li peb tsis tau txais 6 nrog qhov xaus ncaj los txuas rau lub kauj txuas. Peb tom qab ntawd 3D luam tawm lawv thiab txuas lawv mus rau kauj thiab lub cev muaj zog. Stepper motors peb muaj, peb muab tso rau hauv ib lub roob. Nws yuav tuav lub cav thiab coj cov kauj raws txoj kev ncaj.

LCD thiab Keypad

Peb siv Arduino Keypad thiab LCD npo txuas rau hauv 5V cov hlau lead ntawm cov khoom siv hluav taws xob rau lub zog thiab tom qab ntawd mus rau tib lub Arduino Board

Thaiv

Peb pom zoo siv 18 gauge xov hlau. Hauv peb qhov xwm txheej, peb yuav tsum tau txiav txim siab los ntawm kev siv ntau qhov ntsuas vim tias peb khiav tawm ntawm 18 qhov ntsuas

LED Sawb

Peb siv cov hlua LED los teeb lub tshuab. Peb txuas nws mus rau 12V cov hlau lead ntawm lub zog hloov khoom siv. Cov hlua LED uas peb siv ua tsaug tau muaj + thiab - ntawm nws uas ua rau cov txheej txheem txuas nws yooj yim dua.

Kauj Ruam 4: Tus Neeg Txais Nyiaj

Peb siv Coinco BA30B raws li peb tus nqi lees txais. Nws yuav tsum tau txuas ncaj qha rau ntawm phab ntsa ua lub zog siv. Peb ua ke nws nrog 24-pin adapter los ntawm atx fais fab mov los ntsaws rau hauv thiab tso cai txuas yooj yim dua. Cov pinouts peb ua raws yog pom hauv qhov txuas hauv qab no:

techvalleyprojects.blogspot.com/2011/07/ard…

Hauv peb qhov xwm txheej, peb yuav tsum tsim tsa kom nce tus neeg txais daim nqi vim tias tsis li ntawd nws yuav qis dua rau peb lub casing.

Kauj ruam 5: Xeem

Kuaj cov khoom siv hluav taws xob sab nraum lub thawv ua ntej kom ntseeg tau tias cov khoom ua haujlwm. Txhua yam teeb meem uas tshwm sim yuav tsum tau kho ua ntej tso rau hauv lub casing.

Kauj Ruam 6: Cov Khoom Siv Hluav Taws Xob rau Casing

Thaum koj tau sim cov khoom siv hluav taws xob thiab txaus siab rau lawv cov txiaj ntsig, pib tso lawv rau hauv koj lub casing. Kho cov xaim ntev kom lawv haum zoo sab hauv.

Kauj Ruam 7: Xeem Kawg

Thaum muab tso rau hauv lub casing, sim txhua yam ntxiv. Yog tias txhua yam ua haujlwm raws li koj xav tau, nrog koj zoo siab! Koj tau ua lub tshuab muag khoom.

Kauj ruam 8: Arduino Code + Txuas
