2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Hauv qhov haujlwm no peb yuav tau saib luv luv ntawm kev ua lag luam muaj nuj nqi/lub tshuab tsim hluav taws xob txhawm rau txiav txim siab seb cov yam ntxwv twg tseem ceeb rau DIY version. Tom qab ntawd kuv yuav qhia koj yuav tsim lub tshuab hluav taws xob ua haujlwm yooj yim li cas, analog thiab txoj hauv kev. Thaum kawg kuv mam li nthuav qhia koj DIY DDS ua haujlwm tsim hluav taws xob tsim uas tuaj yeem (hom) tuav mus txog kev lag luam. Cia peb pib!

Kauj ruam 1: Saib Video

Cov vis dis aus muab txhua yam ntaub ntawv koj xav tau los tsim koj tus kheej DDS lub tshuab ua haujlwm. Hauv cov kauj ruam tom ntej tab sis, kuv yuav nthuav qhia koj qee cov ntaub ntawv ntxiv.

Kauj Ruam 2: Txiav Koj Cov Khoom

Ntawm no koj tuaj yeem pom cov npe teev nrog piv txwv tus muag khoom (koom nrog txuas):

Kauj ruam 3: Tsim Circuit Court

Ntawm no koj tuaj yeem pom cov txheej txheem ntawm Circuit Court nrog rau cov duab siv ntawm kuv qhov kev tsim ua tiav ntawm cov ntoo. Xav tias dawb siv lawv.

Kauj ruam 4: Upload Code

Ntawm no koj tuaj yeem pom cov cai rau txoj haujlwm no. Koj yuav tsum xa nws mus rau Arduino ua ntej koj lub tshuab hluav taws xob ua haujlwm tuaj yeem ua haujlwm tau zoo.

Ua tsaug ntau dua rau Cezar Chirila rau nws txoj haujlwm. Cov cai yog zoo nkauj npaum li cas los ntawm nws. Saib nws tsab xov xwm:

Kauj Ruam 5: 3D Luam Vaj Tsev

Ntawm no koj tuaj yeem pom cov.stl thiab.123dx cov ntaub ntawv rau kuv 3D luam tsev nyob. 3D luam tawm lawv thiab tom qab ntawd nce tag nrho cov khoom siv sab hauv lub thawv loj kom ua tiav koj lub zog tsim hluav taws xob tsim.

Kauj Ruam 6: Ua tiav

Koj ua nws! Koj tsuas yog tsim koj tus kheej lub luag haujlwm/lub tshuab hluav taws xob waveform!
