- Tsuas yog siv lub cuab yeej rau nws lub hom phiaj. Kev siv lub cuab yeej hauv txoj kev tsis tau tso cai yuav ua rau tsis muaj qhov lav.
- Kev puas tsuaj los ntawm kev tsis saib xyuas qee cov lus qhia hauv phau ntawv no tsis muaj kev lav phib xaub thiab tus neeg muag khoom yuav tsis lees txais kev lav phib xaub rau cov teeb meem tshwm sim los yog teeb meem.
- Tsis yog Velleman Group NV lossis nws cov neeg muag khoom tuaj yeem lav lub luag haujlwm rau kev puas tsuaj ( txawv txawv, xwm txheej, lossis tsis ncaj) - ntawm txhua qhov xwm txheej (nyiaj txiag, lub cev ...) tshwm sim los ntawm kev muaj, siv, lossis tsis ua haujlwm ntawm cov khoom no.
- Khaws phau ntawv no rau yav tom ntej siv.
Arduino® yog dab tsi
Arduino® yog qhov qhib-qhov kev tsim tawm platform raws li cov khoom siv yooj yim siv thiab software. Arduino® boards muaj peev xwm nyeem tau cov tswv yim - lub teeb pom kev zoo, ntiv tes ntawm lub pob, lossis cov lus Twitter - thiab tig lawv mus rau hauv cov zis - ua kom lub cev muaj zog, tig rau LED, lossis tshaj tawm ib yam dab tsi hauv online. Koj tuaj yeem qhia koj lub rooj tsavxwm yuav ua li cas los ntawm kev xa cov lus qhia rau lub microcontroller ntawm lub rooj tsavxwm. Txhawm rau ua li ntawd, koj siv Arduino programming lus (raws li Wiring) thiab Arduino® software IDE (raws li Kev Ua Haujlwm). Cov ntaub thaiv npog ntxiv / modules / cov khoom yuav tsum tau nyeem cov lus Twitter lossis tshaj tawm hauv online. Surf rau www.arduino.cc yog xav paub ntxiv.
