Ua tsaug rau Random Nerd Tutorials thiab 3KU_Delta rau lawv qhov kev tshoov siab, kev pab thiab tus lej.
Kauj Ruam 1: Tus Kws Cob Qub Dej Sensor
3KU_Delta tshaj tawm txoj haujlwm zoo ntawm no ntawm cov lus qhia: Tag Nrho Croc Project
Txoj haujlwm suav nrog tshaj tawm qhov ntsuas kub, lub sijhawm hloov kho zaum kawg, thiab lub roj teeb ntawm Blynk thiab MQTT. Tom qab ntawd nws tau ntxiv cov ntawv txuas ntxiv rau tsim cov duab loj LED thiab pom cov ntaub ntawv ntawm Node Red rau Raspberry Pi.
Kuv hloov ob peb yam:
Kuv xav kom muaj hwj chim ntau dua thiab muaj peev xwm them ntau dua. Yog li kuv:
1. Kuv muab qhov loj dua (6V 1W Solar Cell array) nyob saum cov croc; txawm hais tias qhov no yog 6V raws li kev tawm tsam rau 3.7V, TP4056 khaws qhov hluav taws xob rau lub roj teeb thiab lub Circuit Court kom raug tus nqi.
2. Kuv muab qhov loj dua (2000mAh Rechargeable Lithium Polymer ion Battery Pack sab hauv croc. Hauv kev tshuaj xyuas los ntawm nws thawj daim ntawv, 3KU_Delta pom zoo lub roj teeb loj no.
Lub roj teeb loj tsis haum rau ntawm 5cm los ntawm 7cm Circuit board 3KU_Delta siv, tab sis kuv siv lub rooj tsav xwm loj li cas los xij; nws muab chav ntau rau kuv txhawm rau txhim kho cov khoom siv ntau dua li lub rooj sib tham me me nrog rau tso TP4056 tus tswj hluav taws xob rau tib lub rooj tsavxwm.
Kom paub tseeb tias ESP8266 Wemos D1 mini pro thiab TP4056 yuav tsis muaj peev xwm tau txais cov dej hauv pas dej rau lawv, Kuv tau kaw tag nrho lub rooj tsav xwm hauv Circuit Court siv "Food Saver" cov khoom. Kuv kaw cov khoom siv lub hnab ntim me me Mini muaj nyob ntawm Amazon. Kuv pub cov xov hlau rau Solar Cell, roj teeb, lub kav hlau txais xov, thiab ds18b20 los ntawm ib qho kawg ntawm "hnab" thiab tom qab ntawd kaw lub qhov nrog Silicone sealer.
Los ntawm txoj kev, (raws li 3KU_Delta hais hauv kev tawm lus) nco ntsoov kaw lub ds1820b nrog txheej epoxy nyias kom paub tseeb tias cov dej hauv pas dej yuav tsis ua puas rau lub sensor.
Kauj Ruam 2: Zaub me me (16 X 2) LCD
Kuv xav khaws cov ntaub ntawv los ntawm kuv tus raspberry pi MQTT broker thiab pom cov ntaub ntawv ntawm lub me me LCD zaub. Random Nerd Tutorials tshaj tawm ob txoj haujlwm nrog rau cov kauj ruam kom tau txais ntau MQTT tshaj tawm hauv ib qho Arduino cov phiaj xwm kev xav. Nov yog qhov txuas rau cov khoom ntawd:
dsb18b20 nrog ESP8266
Qhia cov ntaub ntawv ntawm LCD
thiab
Sau npe yuav ua rau ntau yam MQTT cov ncauj lus
Kuv ua tsaug rau Rui Santos rau qhov tso cai rau kuv tshaj tawm cov cai uas kuv tau tsim los ntawm kev hloov kho thiab siv tag nrho peb qho ntawm nws nkag.
Qhov xav tau txhua qhov yooj yim muaj nyob ntawm Amazon lossis Ebay:
1. ESP8266 NodeMCU board
2. 16 X 2 LCD zaub nrog i2c board txuas - nco ntsoov kom tau txais cov zaub nrog i2c board txuas. Qhov ntawd yuav txuag koj ntau lub sijhawm siv cov laug cam i2c rau lub vijtsam LCD.
3. Cov ntaub ntawv yas baseball - Kuv pom ib qho pheej yig heev ntawm Amazon thiab siv tsuas yog ib nrab ntawm rooj plaub. Hmoov tsis zoo, LCD loj dua me ntsis ntawm rooj ntaus pob. Yog tias koj xav tso koj txoj haujlwm rau hauv rooj plaub kaw, qhov tsawg tshaj plaws rooj muag khoom softball pom muaj nyob ntawm Lub Thawv Thauj Khoom.
4. Cov xov hlau txuas luv
5. Thaum tshav kub kub ntsws tub los tuav cov xov hlau nyob hauv qhov chaw.
Raws li koj tuaj yeem pom hauv daim duab saum toj no, Kuv siv tsuas yog ib nrab ntawm rooj plaub. Yog tias koj xav tau rooj plaub loj dua uas kaw, Kuv hais qhia rooj plaub softball. Qhov tsawg tshaj plaws uas kuv pom yog los ntawm Lub Thawv Thauj Khoom (sku#: 44070).
Kuv tshaj tawm kuv tus lej ntawm GitHub: Code
