Lub Hom Phiaj
Kawm paub siv lub ntsuas hluav taws xob sib piv nrog lub micro: me ntsis.
Ua tus electro-theremin!
Kauj ruam 1: Cov ntaub ntawv
1 x BBC micro: me ntsis
1 x Micro USB cable
1 x Buzzer
2 x F-F Jumper Wires
1 x Potentiometer
Kauj ruam 2: Txheej txheem
Kauj ruam 1
Txuas koj lub Buzzer rau Pin0. Ua kom ntseeg tau tias cov hlau lead zoo txuas nrog tus pin teeb liab thiab cov hlau lead tsis zoo txuas nrog rau tus pin dub hauv av ntawm pawg thawj coj.
Txuas lub hwj chim rau Pin1. Koj tuaj yeem ntsaws raws li xim. Nco ntsoov tias cov xim hlau thiab cov xim tus pin ntawm pawg thawj coj saib puas zoo sib xws!
Kauj ruam 2
Hauv Makecode, peb yuav taug qab tus nqi ntawm lub hwj chim siv qhov sib txawv. Variables zoo li cov thoob uas tuaj yeem tuav tus nqi hloov pauv.
Ua qhov hloov pauv tshiab hu ua nyeem ntawv (lossis ib yam dab tsi uas koj nyiam, tiag tiag) hauv cov ntawv hloov pauv.
Peb xav kom teeb tsa peb qhov kev nyeem nyeem sib txawv mus rau tus nqi sib piv ntawm lub zog potentiometer hloov pauv ntawm digital.
Nyeem qhov sib piv tso cai rau peb nkag mus rau tag nrho cov cim ntawm lub zog, tsis yog tsuas yog digital 1 lossis 0. Nrhiav qhov thaiv hauv Pins tub rau khoom.
Kauj ruam 3
Txheeb xyuas koj qhov tsawg kawg thiab qhov siab tshaj plaws rau koj lub hwj chim los ntawm kev qhia tus lej ntawm kev nyeem sib txawv.
Tig lub pob qhov rooj los rau ntawm txhua txoj hauv kev muab rau koj yam tsawg kawg nkaus, thiab txhua lub moos raws txoj hauv kev muab rau koj siab tshaj plaws.
Daim ntawv ceeb toom yuav ua li cas tus nqi dhia? Qhov ntawd yog vim tias micro: me ntsis siv sijhawm me ntsis los rub tus lej loj hla lub vijtsam, thiab los ntawm lub sijhawm koj nyeem tus nqi tshiab, lub hwj chim yuav yog txoj hauv kev ua ntej!
Kauj ruam 4
Tam sim no peb tab tom siv cov txiaj ntsig uas koj nyuam qhuav nyeem los ntawm koj lub hwj chim ntsuas los qhia tawm koj cov ntawv!
Peb cov suab paj nruag yuav tsis muaj ntau yam dav li koj lub hwj chim. Hauv qhov piv txwv no, peb xav kom ntseeg tau tias tus nqi siab tshaj plaws potentiometer tseem sib xws rau daim ntawv siab tshaj plaws uas peb tuaj yeem ua si.

Kev Tsim Qauv Duab Duab/Duab Duab Duab: Nyob zoo txhua tus, Hauv qhov kev qhia no, Kuv yuav qhia koj cov txheej txheem ntawm yuav ua li cas thiaj tsim 3D qauv siv cov duab digital. Cov txheej txheem hu ua Photogrammetry, tseem hu ua Image-Based Modeling (IBM). Tshwj xeeb, hom txheej txheem no tau siv los rov ua dua
Tsim Kev Tsim Kho - Kev Hloov Kho ntawm Digital Bonsai Tree: 15 Cov Kauj Ruam (nrog Duab)
Kev Tsim Tsim Tsim - Kev Hloov Kho ntawm Digital Bonsai Tree: Kuv pib ua haujlwm nrog Pab Pawg Tshawb Fawb ntawm Autodesk nrog Dreamcatcher txog 2 xyoos dhau los. Lub sijhawm ntawd kuv tau siv nws los tsim lub dav hlau. Txij li lub sijhawm ntawd kuv tau kawm paub hlub lub cuab yeej software no vim nws tso cai rau kuv tshawb fawb ntau txhiab tus qauv
