Hauv zej zog niaj hnub no, kev nce hauv cov neeg caij tsheb ciav hlau txhais tau tias cov tuam txhab tsheb nqaj hlau yuav tsum ua ntau ntxiv txhawm rau txhim kho cov kev sib txuas kom ua tau raws li qhov xav tau. Hauv qhov haujlwm no peb yuav qhia me me seb qhov kub thiab txias, dej nag, thiab kev co lub zog ntawm lub rooj tsav xwm arduino tuaj yeem pab txhawb kev nyab xeeb ntawm cov neeg caij tsheb.

Cov Lus Qhia no yuav qhia ib qib zuj zus qhia cov kab hluav taws xob rau qhov ntsuas kub, dej nag, thiab kev ntsuas kev co ntawm lub arduino nrog rau qhia MATLAB cov cai uas yuav tsum tau ua los ntsuas cov ntsuas no.
