STEMs feem ntau siv cov thooj av hauv Circuit Court, tab sis nws muaj ntau ntau hom khoom, thiab ntau yam khoom muaj ruam. Hauv qhov teeb meem no, peb qhia peb yam khoom thiab ntxiv ib cov ntsiab lus muaj feem xyuam.
Feem ntau cov liab boards tsis yog Arduino thiab Txiv Pos, thiab lub xyoo no micro: me ntsis kuj muaj qhov chaw. Dab tsi yog qhov txawv ntawm qhov peb?
Paub txog ob lub tswv yim
Ua ntej peb tau teev nyob rau hauv kev nthuav dav, ob lub ntsiab lus piav qhia ua ntej, ib qho yog Micro Processing Unit (MPU), thiab lwm qhov yog Micro Control Unit (MCU).
Microprocessor
Lub tswvyim ntawm MPU tsis yog qhov nyuaj. Tag nrho cov qauv tsim yog zoo li lub tshuab computer. Feem ntau ntawm cov khoom tiav tau ua tiav kev khiav haujlwm, ua haujlwm kom tiav, thiab cov kab lus zoo li lub computer me, tab sis nws me dua, thiab qhov ua haujlwm tsawg dua, kev khiav haujlwm tsawg dua. Qhov kev ua haujlwm yog cov neeg pluag, lub cheeb tsam me me me me, tus nqi qes qis, thiab kev siv fais fab yog me me. Txawm li cas los xij, nrog kev ua tiav ntawm kev siv tshuab semiconductor, txoj kev loj hlob ntawm MPU series tau dhau los ze zog thiab ze rau cov computers. Ib qho ntawm cov neeg sawv cev ntawm cov neeg sawv cev hauv cheeb tsam ntawm STEM yog tus Tub Ntxhais Hluas. Nws yog tsim nyog hais tias qee cov neeg tau tsis ntev los no tau hais txog SoC (System on Chip), uas muaj peev xwm siv ntau txoj haujlwm, xws li Wi-Nkaus, thiab lwm yam, tiam sis vim yog lub siab tsis yooj yim, nws yog qhov tsim nyog rau kev sib tham zoo.
MPU xws li cov computers me, ntau tus neeg qhov kev kawm thawj zaug yog los tsim lawv cov kev sib tw game consoles.
Microcontroller
MCU yog sib dua MPU, thiab nws lub hom phiaj tsim muaj ntau dua. Qhov kev khiav hauj lwm saum toj no, xam phaj, chip cheeb tsam, cov nqi thiab kev siv zog muaj zog ntxiv. Nws ua haujlwm tsis zoo li lub computer. Yog tsis muaj kev ua haujlwm hauv tsev. Kev txhim kho kev zov me nyuam yuav tsum tau siv los ntawm lwm lub tshuab. Sau thiab rov nkag, tab sis nws cov qauv siv yooj yim ua txhua yam sai dua thiab ncaj qha. Qee cov lag luam tuaj yeem ncaj qha mus rau lub sensor, yog li ntawd lawv tuaj yeem siv rau cov khoom siv niaj hnub xws li hluav taws xob ua si, hluav taws xob fais fab, sphygmomanometers, haus luam yeeb. Ntes, thiab lwm yam. Yam khoom sawv cev hauv cheeb tsam ntawm STEM yog micro: Me ntsis thiab Arduino.
Arnav Sharmay tsim cov khoom siv kev tswjhwm Asthma
Ntxiv ib qho taw qhia, qhov kev cais saum toj no yog lub ntsiab lus. Hauv kev xyaum, ob qho tib si ntawm cov hoob kawm yuav tau pib ntawm nws tus kheej, los yog lawv tuaj yeem ua ke kom nkag siab qhov kev tsim lawv xav tau. Tom qab ntawd paub qhov ua tau zoo thiab ua tau zoo ntawm ob qho tib si, ua kom yooj yim dua tuaj yeem kho cov cuab yeej kho mob.
Peb cov khoom introductions
Ntxiv nrog rau qhov kev qhia ntawm cov tswv yim saum toj saud, cov nram qab no piav qhia txog cov qauv qauv thiab keeb kwm ntawm peb cov khoom, uas yuav pab koj nkag siab txog txoj cai.
Cov tub ntxhais kawm ntawv hauv British: micro: me ntsis
Pib xyoo 2012, tsoom fwv UK muab ib lub micro pub dawb: me ntsis lub rooj sib tham rau cov me nyuam hauv zos ntawm hnub nyoog 11 thiab 12. Cov pob zeb no muaj ntau yam khoom siv thiab muaj teeb meem nrog 5 x 5 tag nrho 25 LEDs, sab laug thiab txoj cai alligator clips ntawm lub rooj tsavxwm, thiab siv tau nrog JavaScript, Nab hab sej. Tos kev programming.Qhov zoo dua yog kev ncaj thiab yooj yim, tab sis nws cov qauv tsim tsis zoo rau txoj kev sib txuas ntawm kev yuam kev loj heev, tiam sis nws tseem yog qhov tseem ceeb rau kev nkag mus, tshwj xeeb tshaj yog rau cov tub ntxhais kawm ntawv qib siab mus rau theem nrab. Tom qab tag nrho, txoj kev thaiv kev lim yuav txo qhov kev xav tau kom tswj txoj kab txuas. Tej teeb meem xws li vuam los yog kev sib txuas cov ntawv qhia.
Tus txwv zeejcoog ntawm tus nqi qes qis micro-tsim: Arduino
Arduino pib txoj kev loj hlob nyob rau hauv 2003. Nws yog ib qhov kev pab cuam lub npe. Thawj lub tswv yim yog txo cov nqi kawm rau cov menyuam kawm ntawv qib siab college. Yog li, feem ntau ntawm cov kev pabcuam muaj feem xyuam raug tsim los ntawm qhib qhov chaw. Ntau yam tsim khoom tsim txij thaum ntawd los kuj tau kev txhawb los ntawm cov koom haum xws li Maker Faire. Txog rau tam sim no, muaj ntau lub versions ntawm txoj kev loj hlob, thiab nkag nkag qib tseem yog tus UNO feem ntau nyob rau hauv qhov Rhiav, thiab cov Mega nrog ntau connected interfaces.Thaum cov kev pab cuam interface, yeej muaj nplooj siab ARDUINO 1.8. 3 txoj kev loj hlob, uas tau muab tso rau ntawm txhua qhov kev khiav hauj lwm lub; tseem muaj kev kawm zoo ib yam li Java thiab C. Qhov tsim nyog rau cov neeg laus tuaj yeem siv kev kawm.
Nqis tshuab computer: Txiv pos Pi
Lub Lub Hauv Paus tseem yog ib yam khoom tseem ceeb ntawm British, tab sis nws tau tsim los ntawm lub Foundation thiab pib ncig lub xyoo 2012. Nws yog tsim los txhawb cov kev qhia txog kev lag luam hauv computer. Yog li ntawd, raws li tag nrho cov computers, lub nrob qaum tso tawm xws li processor, nco, USB, Ethernet, HDMI, RCA, thiab lwm yam. Lub ntim yog hais txog ib daim credit card loj thiab yog SD. Daim card yog siv los ua nruab nrab nruab nrab, thiab Linux system operating system tseem muab cia rau hauv SD card, tiam sis nws kuj txhais tau hais tias nws muaj qhov browser, daim ntawv teev software, thiab cov zoo li.Qhov kev zoo dua yog tias nws tsis xav tau mus cuag rau lwm cov kev khiav haujlwm thiab txhawb ntau hom lus programming. Txawm li cas los, vim yog siv Linux, nws yog qhov khoom nruab nrab-rau-high-end thiab tsuas yog haum rau cov neeg hauv cov tsev kawm ntawv theem ob los sis siab dua.
Lwm cov ntsiab lus sib xws
Cov kab lus saum toj no yuav tsim tau ncaj qha ua cov neeg hlau lossis cov khoom ntse. Txawm li cas los, tom qab xyoo ntawm txoj kev loj hlob, yuav kom ua tau raws li kev tsim cov qauv tsim, feem ntau lawv muaj ntau hom accessories.
Sensor
Sensors yog tsim kho hluav taws xob, feem ntau yog siv los ntsuas ultrasonic, thiab gyroscopes los mus sau cov ntaub ntawv qhia peb, nrog rau kev hnov suab, kev hnov qab, kev hnov siab, kev ntsuas, thiab qhov teebmeem. Kev hnov, qhov ntom nti, kev hnov lub suab, thiab CO2 tsom.
Shield
Lub sensor zoo ib yam li lub rooj tsav xwm nthuav tawm. Lub hom phiaj ntawm lub rooj tsav xwm nthuav tawm yog ntxiv cov kev ua haujlwm ntawm pawg thawj coj saib kev ncaj ncees. Lub rooj tsav xwm nthuav dav yuav ntxiv ntau yam raws li qhov xav tau, xws li kev sib txuas hauv network los yog kev sib tw shooting, thiab lub rooj tsav xwm nthuav dav yuav muab ntau lub tshuab ua ke, thiab lub rooj tsav xwm nthuav tawm tsuas yog rau cov khoom.
