Muaj ntau qhov chaw sib txawv rau cov qauv no. Tsis yog txhua tus qauv uas zoo ib yam rau cov ntawm no coj tus yam ntxwv zoo ib yam. Txheeb xyuas qhov tshwj xeeb uas koj muaj rau qhov sib txawv hauv kev ua haujlwm, qib hluav taws xob, pinout, thiab cov xeev tsis ua haujlwm/ua haujlwm. Qee qhov qauv tau pom tias muaj cov cim npe tsis raug thiab txawm tias cov khoom siv tsis zoo.

Kauj Ruam 3: Cov Khoom Siv LED RGB

Tsuas yog pom cov hauv paus ntawm qhov kev ua haujlwm no ua haujlwm li cas, qhov kev sim no qhia tau tias yuav cuam tshuam nws li cas kom yooj yim-rau-nkag siab microcontroller board, Sensor. Engine: MICRO. Tsis tas yuav xav tau cov txheej txheem txhim kho nyuaj raws li 32-ntsis micro uas yog ib feem ntawm pawg thawj coj no muaj tag nrho cov ntse ua hauv.

Txoj cai rau lwm lub microcontroller platform yuav zoo ib yam lus/syntax, tab sis zoo ib yam.

Nov yog cov npe me me ntawm cov khoom siv rau qhov kev sim no:

RGB LED Module los ntawm 37 Cov Khoom Siv. (Qhov kev sim no qhov chaw: CircuitGizmos) Cov khoom siv kuj muaj nyob ntawm Amazon thiab online hauv ntau qhov chaw.

Jumper Wires, poj niam rau poj niam "DuPont" style. (Qhov kev sim no lub hauv paus: CircuitGizmos) Cov dhia dhia ntawm hom no kuj muaj nyob online.

Microcontroller Board. (Qhov kev sim no lub hauv paus: CircuitGizmos)

Lub PC nrog daim ntawv thov davhlau ya nyob twg tau siv los sib txuas lus nrog pawg thawj coj ntawm USB. Ib txoj haujlwm pub dawb thiab muaj txiaj ntsig zoo li Beagle Term.

Nrog rau txhua qhov no, koj tuaj yeem ua qhov kev sim los ntsuas RGB LED Module.
