LEDs zoo heev rau kev ua lub teeb, tab sis lawv tuaj yeem hnov lub teeb ib yam! Kuv nyuam qhuav dawm ntawm qhov chaw no uas hais txog, "Xyoo 1977, Forrest M. Mims nco txog peb hauv nws ntawm" Engineer Notebooks "uas LEDs kuj tseem tuaj yeem siv ua cov duab thaij duab … "Nplooj ntawv muaj cov lej LED uas siv los ua ntau qhov kov tab sis muab cov ntaub ntawv me me. Kuv tseem tsis muaj lub tswv yim yuav ua li cas nws txoj haujlwm, tab sis kuv tau kawm paub siv LEDs li lub teeb pom kev li cas. Cov lus qhia no mus dhau kuv qhov kev sim nrog ntau hom LEDs ua lub teeb pom kev zoo thiab ua kom tsaus ntuj tsaus ntuj siv lub teeb ci siv LEDs ua lub ntsej muag.
Kauj Ruam 1: Yam Koj Yuav Tsum Tau
- random ntau yam ntawm LEDs
- tam sim no txwv resistors rau LEDs
- multimeter
- daim ntawv qhia zaub mov
- teeb nyem ci
- microcontroller (Kuv siv Arduino)
Kauj Ruam 2: Nws Ua Haujlwm Li Cas?
Raws li Wikipedia: LED ua lub teeb pom kev zoo: "Ib qho LED tsuas yog lub diode uas tau raug doped tshwj xeeb rau lub teeb pom kev zoo thiab tau ntim rau hauv rooj plaub pob tshab. yog qhov tseem ceeb tib yam, LED yuav ua haujlwm zoo ib yam. "Photodiode:" Lub photodiode yog ib hom photodetector muaj peev xwm hloov pauv lub teeb mus rau tam sim no lossis qhov hluav taws xob, nyob ntawm seb hom kev ua haujlwm."
Kauj ruam 3: Paub
Txhua yam koj yuav tsum ua yog nqes mus rau lub ntsuas cua kom nyeem qhov hluav taws xob tawm los ntawm LED, yog li ntawd! Sim taw tes rau LED ntawm qhov sib txawv ntawm lub teeb pom kev thiab saib yuav ua li cas nyeem ntawv hloov pauv.
Kauj Ruam 4: Kev sim nrog LEDs sib txawv
