Fade LED Nrog 555timer
Fade LED Nrog 555timer

Qhov no yog Fade LED. Nws yog lub voj voog me me uas ploj rau thiab tawm thaum koj qhib lossis kaw lub Circuit Court. Nws khiav ntawm 555timer thiab 2n222 transistor. Nws yog ib qho me me thiab yooj yim Circuit Court.

Kauj Ruam 1: Cheeb Tsam

Hauv kab lus no koj yuav xav tau:

1 x Breadboard

1 x 9v pin

1x 9v roj teeb txuas

6x jumper kab

1 x LED

1x 220uf (lossis ntau dua) capacitor

1 x 2n222 transistor

1x 555timer nti

2 x 10 k resistor

1x 2.2k resistor (nyob ntawm ntau npaum li cas tam sim no koj LED xav tau)

Kauj Ruam 2: Cheeb Tsam Hneev taw

Yog tias koj tseem tsis tau paub txog cov ntawv hneev taw, ces nws yuav yog lub tswv yim zoo kom paub lawv.

Hauv daim duab saum toj no, nws yuav qhia koj qhov kev tivthaiv hneev taw (cim) nrog rau yam khoom uas nws yog.

Kauj ruam 3: Tsim Nws

Tam sim no koj tau npaj los pib tsim kho!

Ib daim duab saum toj no qhia koj txhua qhov tshwj xeeb muaj nuj nqis, thaum lwm qhov qhia tau hais tias tag nrho cov ntawv ci.

Nco ntsoov txoj hauv kev txoj kev txoj kev 555 timer thiab transistor ntsej muag. Nco tseg: tsis quav ntsej '555' sau rau ntawm lub nti, ua raws cov lej ntawm nws.

Kauj Ruam 4: Xeem & Ua tiav

Tam sim no koj ua tiav, koj tuaj yeem sim koj lub Circuit Court kom pom tias nws ua haujlwm li cas.

Yog: Yog tias nws ua haujlwm ces qhov no yuav tshwm sim: Thaum qhib hluav taws xob, LED yuav siv ob peb feeb ua ntej nws teeb. Thaum nws taws, nws yuav tsum nyob twj ywm. Thaum koj tua lub Circuit Court, ces LED yuav tsum maj mam ploj mus.

Tsis yog: Yog tias LED tsis ploj, koj tau txuas lub tshuab hluav taws xob tsis raug lossis nti tsis raug. Yog tias LED yooj yim tsis pom, tom qab ntawd koj muaj qhov yuam kev thaiv, yog li koj yuav tsum rov tshuaj xyuas dua.

Kauj ruam 5: Tricks

Tam sim no koj muaj lub voj voog ua haujlwm, koj tuaj yeem sim hloov kho nws.

Txhawm rau hloov ces ploj tus nqi, koj tsuas yog hloov lub capacitor. Qhov muaj peev xwm ntau dua, qhov ntev dua qhov ploj mus thiab rov ua dua
