LED yog sawv rau lub teeb emitting diode. Teeb ua qhov taw qhia zoo heev. Lawv siv hluav taws xob tsawg heev thiab lawv zoo nkauj npaum li cas tas mus li.

Hauv zaj lus qhia no.you yuav siv kab tias feem ntau ntawm txhua tus LED s, 5 hli liab coj. 5 hli hais txog txoj kab uas hla ntawm LED. Lwm qhov ntau thiab tsawg yog 3 hli thiab 10 hli.you tsis tuaj yeem txuas ncaj qha rau LED rau roj teeb lossis qhov hluav taws xob vim vim.

1. Lub LED muaj qhov ua tau zoo thiab ua rau tsis zoo thiab yuav tsis pom kev yog tias tso qhov tsis raug thiab

2.an LED yuav tsum tau siv nrog tus tiv thaiv kom txwv lossis 'choke' tus nqi tam sim no ntws los ntawm nws lwm yam, nws yuav hlawv tawm!

yog tias koj tsis siv tus tiv thaiv nrog thiab LED, tom qab ntawd nws yuav raug rhuav tshem yuav luag tam sim, vim tias ntau dhau tam sim no yuav ntws los, ua kom sov nws thiab rhuav tshem 'kev sib tshuam' qhov twg lub teeb tsim tawm

Muaj ob txoj hauv kev los qhia qhov twg yog qhov ua tau zoo ntawm LED thiab qhov tsis zoo.

Ua ntej, qhov ua tau zoo yog ntev dua.

Qhov thib ob, qhov twg cov hmoov txhuas tsis zoo nkag mus rau hauv lub cev LE, muaj ib lub tiaj tiaj rau rooj plaub ntawm LE.

Yog tias koj tshwm sim kom muaj LED uas muaj lub tiaj tiaj nyob ib sab ntawm cov hlau lead ntev dua, koj yuav tsum xav tias cov hlau lead ntev dua yog qhov zoo.

Kauj Ruam 1: Cov Khoom Yuav Tsum Tau

1. Arduino UNO

2. LED

3. Resistor

4.jumper xov hlau

Kauj ruam 2: Schematic

txuas lub resistor rau sab zoo ntawm LED thiab qhov tsis zoo rau hauv av.
