2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29
"Tus Me Phooj Ywg Tham" yog lub cuab yeej me me uas tso cai rau koj ntxiv cov suab yooj yim tso rau koj cov phiaj xwm Arduino. Nws muaj cov lus txwv ntawm 254 lus thiab tuaj yeem txuas nrog Arduino lossis lwm lub microcontrollers ntawm SPI. Tus Me Phooj Ywg Tham (LBT) tau tsim los ntawm Patrick Mitchell, cov ntaub ntawv ntau ntxiv tuaj yeem nrhiav tau ntawm nws lub vev xaib www.engineeringshock.com. LeRoy Miller tau tsim lub tsev qiv ntawv kom yooj yim siv LBT hu ua lo lus 100 thiab Matt Ganis tau tsim cov ntawv txaus kom yooj yim nyeem cov lej uas siv lo lus 100 lub tsev qiv ntawv. Hauv qab no kuv yuav piav qhia qhov ntsuas kub sib tham yooj yim / ntsuas sov raws li lub ntsuas Si7021, Arduino thiab Me Me Buddy Talker. Txog tam sim no nws tsis yog ntau tshaj qhov pov thawj ntawm lub tswv yim. Kuv siv Si7021 kev tawm los ntawm Adafruit thiab tsuas yog ua ke Si7021 tus qauv sau los ntawm Adafruit nrog tsab ntawv los ntawm Matt Ganis. Koj kuj tseem yuav tsum teeb tsa Adafruit Si7021 thiab Lo Lus 100 lub tsev qiv ntawv.
Kauj ruam 1: Cov ntaub ntawv
Me Phooj Ywg Tham - 25 CA $. Kuv tau txais kuv li los ntawm Kickstarter project. Xav paub ntau ntxiv ntawm www.engineeringshock.com. Si7021 breakout - Kuv siv Adafruit breakout, txog 7 US $. Cov lus piav qhia ntxaws thiab cov lus qhia muaj nyob ntawm Adafruit lub vev xaib. Arduino Uno - Kuv tau siv Monkmakesduino, tab sis ib qho qauv twg yuav tsum ua haujlwm. Lub thawv ntawv, qee lub jumper cables, lub mloog pob ntseg lossis hais lus. Koj yuav tsum tau teeb tsa qee lub tsev qiv ntawv. pom ntawm https://github.com/kd8bxp/Word100The Si7021 lub tsev qiv ntawv los ntawm Adafruit tuaj yeem pom ntawm no: https://github.com/adafruit/Adafruit_Si7021 Tus thawj ntawm Matt Ganis 'tsab ntawv tuaj yeem pom ntawm
Kauj ruam 2: teeb tsa lub cuab yeej
Kev teeb tsa lub cuab yeej yog qhov yooj yim heev thiab nrawm: Tus Phooj Ywg Me Tham Nrog txuas nrog Arduino ntawm SPI, mus rau Si7021 kev tawg ntawm I2C.
- Txuas cov chaw nres nkoj cim Gnd, Vin, Scl thiab Sda ntawm lub sensor mus rau chaw nres nkoj GND, 5V, A5 thiab A4 ntawm Arduino.
- Txuas 5V, GD, DI, SC thiab CS cov chaw nres nkoj ntawm 'Me Buddy Talker' mus rau cov chaw nres nkoj 5V, GND, 11, 13 thiab 10 ntawm Arduino. Lub khob cij thiab jumper xov hlau tuaj yeem pab tau.
- Txuas tus neeg hais lus lossis lub mloog pob ntseg mus rau lub mloog pob ntseg ntawm LBT.
- Nruab ib lub tsev qiv ntawv uas xav tau hauv Arduino IDE.
- Rub cov ntawv piv txwv (saib cov kauj ruam tom ntej) rau koj Arduino.
Cov txiaj ntsig ntawm kev ntsuas tau qhia ntawm lub ntsuas saib thiab hais lus. Kev ntsuas ntsuas tau kwv yees li ob zaug ib feeb, uas tuaj yeem hloov kho hauv cov ntawv yooj yim heev hloov tus nqi 'ncua'.
Lub hauv paus tab sis txwv tsis pub dhau ntawm Me Me Buddy Talker yog txwv cov lus. 'point' yog lo lus uas ploj lawm, ua rau nws nyuaj rau 'hais lus' tus lej taw tes ntab. Yog li thaum Si7021 tuaj yeem ntsuas qhov ntsuas kub kom raug, kuv tau txo cov ntaub ntawv mus rau tag nrho cov lej.
Cov av noo qhov tseem ceeb tau muab ua piv txwv cov av noo hauv %. Hmoov tsis zoo, lo lus 'feem pua' tseem ploj thiab. Yog li kuv tau sim hloov nws nrog kev sib xyaw ntawm 'ib' thiab 'centi', txawm tias 'ib-centi' suab tsis txaus ntseeg me ntsis. Thaum lub sijhawm sau ntawv, muaj Kickstarter project rau qhov loj dua nrog ntau dua 1000 lo lus, 'Big Buddy Talker', uas tuaj yeem tso cai hla qhov kev txwv no. Thaum cov ntawv nyob ntawm Arduino, koj tuaj yeem khiav lub cuab yeej ua kom nws los ntawm lub hwj chim. Kuv siv qhov teeb tsa no tso rau hauv lub tub yees, nrog cov hais lus ntawm lub mloog pob ntseg sab nraud. Nws tseem ua haujlwm ntawm -19 ° C. Thaum muaj kev hloov pauv loj ntawm cov av noo lossis qhov kub, lub ntsuas cua xav tau qee feeb los kho. Yog li ua siab ntev thiab tos kom txog thaum qhov txiaj ntsig tau ruaj khov.
Kauj Ruam 3: Tsab Ntawv, thiab Project Outlook
Koj tuaj yeem rub tawm tsab ntawv los ntawm no. Raws li tau hais, nws tsuas yog kev sib sau ua haujlwm ntawm lwm tus, nrog qee qhov kev hloov me me. Koj tuaj yeem hloov kho tsab ntawv raws li koj nyiam, tab sis thov khaws cov cai ntawm Matt Ganis thiab LeRoy Miller.
Txuas nrog koj tseem pom cov npe ntawm cov ntsiab lus Me Me Buddy Talker muaj peev xwm hais tau, ib qho kev hais tawm los ntawm LeRoy Millers cov ntaub ntawv. Koj tsuas yog tso rau Little Buddy Talker hais tus lej los ntawm -99 txog 99, cov ntawv yooj yim dua yuav txaus. Tab sis kuv xav siv tsab ntawv no thiab daim ntawv thov ua kev sim rau kev tsim qauv zoo sib xws nrog lwm cov ntsuas uas tuaj yeem tshaj tawm cov lej ntev raws li qhov muaj txiaj ntsig, piv txwv li lub teeb lossis xim xim. Nyob twj ywm.
Lwm qhov piv txwv rau kev sib txuas ntawm LBT thiab lub ntsuas hluav taws xob tuaj yeem pom ntawm no:
Txhua yam lus qhia, lus pom thiab kev kho raug txais tos.
