Nyob zoo!

Hauv cov lus qhia no, peb yuav qhia koj yuav ua li cas tsim ib qho LED Dimmer Circuit uas ua haujlwm ntawm lub sijhawm hloov kho tau siv lub zog siv lub zog, lub sijhawm 555 thiab lwm yam khoom siv hluav taws xob yooj yim. Peb thawj zaug tau txais lub tswv yim rau txoj haujlwm no los ntawm lwm cov lus qhia uas ua rau cov kab hluav taws xob LED tswj los ntawm kev hloov dimmer, pom ntawm no: https://www.instructables.com/id/LED-Strip-Control-With-Dimmer-and-Audio -Pulsing-Ci/. Txoj haujlwm no tau pab tau zoo kawg hauv kev nkag siab yuav ua li cas lub tshuab hluav taws xob tuaj yeem ua haujlwm li qhov hloov pauv dimmer. Rau peb lub hom phiaj, txawm li cas los xij, peb xav teeb tsa lub hwj chim ntsuas hluav taws xob ua lub sijhawm hloov pauv uas tau tswj hwm lub sijhawm ntev nws yuav siv rau LED sawb kom ploj mus thiab tawm. Vam tias koj pom qhov no muaj txiaj ntsig!

Thaum lub voj voog tiav thiab tag nrho muab tso ua ke, koj yuav tsum txuas koj lub Circuit Court mus rau oscilloscope kom pom tias cov nthwv dej tso tawm zoo ib yam li qhov tau hais los saum no. Kev txuas ib tus coj ntawm oscilloscope mus rau hauv av thiab lwm qhov mus rau qhov zoo tso tawm dav hlau LED sawb yuav txuas rau hauv cov kauj ruam tom ntej.

R2 kho lub sijhawm ploj ntawm nthwv dej.

R3 kho qhov ploj thaum lub sijhawm nthwv dej.

R7 kho qhov oscillation qhov dav ntawm nthwv dej, cuam tshuam rau qhov pom kev ci ci ntawm Circuit Court.

R6 kho DC offset, hloov pauv qhov ntau ntawm qhov hluav taws xob dhau los ntawm LED sawb.
