Txoj haujlwm no mus dhau cov txheej txheem Kuv tau siv los tsim lub tais zaub mov miv tsis siv neeg, rau kuv cov laus muaj ntshav qab zib miv Chaz. Saib, nws xav tau noj tshais ua ntej nws tuaj yeem tau txais nws cov insulin, tab sis kuv feem ntau tsis nco qab khaws nws cov zaub mov ua ntej kuv mus pw, uas ua rau nws qab los noj mov thiab cuam tshuam nws lub sijhawm insulin. Cov tais no siv lub tshuab servo kaw lub hau ntawm cov khoom noj thaum ib tag hmo ib tag hmo thiab 7:30 sawv ntxov. NodeMCU ESP8266 microcontroller's Arduino kos duab siv Network Time Protocol (NTP) los tswj lub sijhawm.

Txoj haujlwm no yuav tsis haum rau cov menyuam yau, ua haujlwm ntau dua. Chaz laus heev thiab tsis muaj zog, nws tsis xav sim txhawm rau qhib lub tais, tab sis nws muaj peev xwm ua tau.

Yog tias koj tshiab rau Arduino lossis ESP8266, koj yuav txaus siab rau cov lus qhia ua ntej hauv qab no:

• Instructables Arduino Class
• Instructables Internet of Things Class

Khoom siv

• 3D tshuab luam ntawv (Kuv siv Creality CR-10s Pro)
• 3D tshuab luam ntawv ntsiabteeb (Kuv siv kub PLA)
• NodeMCU ESP8266 wifi microcontroller
• USB cable (A rau microB)
• USB zog adapter
• Micro servo tsav
• Ntsia taub hau me me thiab ntsia hlau
• Hookup hlau
• Header tus pin
• Perma-proto pawg thawj coj saib

Txhawm rau ua raws qhov kuv tab tom ua haujlwm, ua raws kuv hauv YouTube, Instagram, Twitter, Pinterest, thiab sau npe yuav rau kuv tsab ntawv xov xwm. Raws li Amazon Kev Koom Tes Kuv khwv tau los ntawm kev tsim nyog yuav khoom koj ua siv kuv cov koom nrog txuas.

Kauj Ruam 1: 3D Luam Qhov Chaw

Tus tuav lub tais zaub mov miv yog ua raws Ardy Lai tus tsim ntawm Thingiverse. Kuv ua kom nws loj dua kom haum kuv tus miv lub tais, thiab tseem ua rau nws luv dua vim qhov ntsuas nws tau ua rau nws siab dhau. Kuv tau ntxiv tus tuav rau lub micro servo motor, thiab ob peb lub qhov rau cov hlua txuas mus rau sab hauv.

Kuv ua qauv lub hau yooj yim siv Tinkercad, tsim los txuas rau lub suab ntawm lub micro servo. Koj tuaj yeem tuav kuv tus qauv ncaj qha los ntawm Tinkercad, thiab/lossis rub tawm STLs txuas nrog rau theem no.

Kuv tau luam tawm ib feem ntawm kuv Creality CR-10s Pro tshuab luam ntawv nrog kub PLA filament.

Kev nthuav tawm: thaum lub sijhawm sau ntawv no, Kuv yog ib tus neeg ua haujlwm ntawm Autodesk, uas ua rau Tinkercad.

Kauj Ruam 2: Txuas lub hau rau Servo Motor

Kuv siv lub qhov me me los txhawm rau kom qhov loj me ntawm lub qhov ntawm servo horn, tom qab ntawd siv cov ntsia hlau los txuas cov servo rau 3D luam tawm lub hau.

Kauj Ruam 3: Tsim NodeMCU ESP8266 Circuit

Lub Circuit Court yog tswj los ntawm NodeMCU ESP8266 wifi microcontroller. Kuv siv tus pin header rau ntawm perma-proto board los ua kom lub micro servo motor yooj yim tshem tawm tau. Qhov servo headers txuas nrog NodeMCU raws li hauv qab no:

Daj servo hlau: NodeMCU D1

Liab servo hlau: NodeMCU zog (3V3 lossis VIN)

Dub servo hlau: NodeMCU hauv av (GND)

Kauj ruam 4: Upload Arduino Code thiab Test

Txhim kho koj lub cav/lub hau sib dhos rau hauv lub tshuab txiav tawm ntawm lub tais tais 3D luam tawm ib feem. Ntsaws lub taub hau lub cev rau hauv lub microcontroller board's header pins, thiab ntsaws lub Circuit Court rau hauv koj lub computer nrog USB cable.

Daim duab Arduino siv Network Sijhawm raws tu qauv los nqa lub sijhawm tam sim no thiab tom qab ntawd qhib lossis kaw lub hau raws li lub sijhawm nyuaj. Luam theej cov cai hauv qab no, hloov kho koj li ntawv pov thawj wifi thiab UTC lub sijhawm offset, thiab xa nws mus rau koj NodeMCU pawg thawj coj siv Arduino IDE.

Kauj ruam 5: Siv nws

Teem koj cov xov hlau mus rau sab hauv ntawm lub tais tais, thiab ntsaws koj tus miv pub rau hauv qhov hluav taws xob siv USB AC adapter. Txoj hauv kev sau cov lej yooj yim, nws lub ntsiab lus yuav tsum tau khau raj hauv lub xeev "qhib", thiab tsuas yog yuav hloov nws txoj haujlwm lub hau thaum lub sijhawm pib tau teev tseg hauv Arduino daim duab.

Tsaug rau ua raws nrog! Yog tias koj ua koj tus kheej version, Kuv xav pom nws hauv I Made It section hauv qab no!
