Ua Koj Tus Kheej (Seesaw) Ob Chav LED Dimmer: 4 Cov Kauj Ruam

Hnub no, kuv yuav qhia koj yuav ua li cas Ob Chav LED Dimmer nrog tsuas yog 555timer chips nrog rau cov khoom sib xws.

Zoo ib yam li MOSFET/Transistor Ib Leeg (Xeem PNP, NPN, P-channel, lossis N-Channel) uas kho qhov ci ntawm LED, qhov no siv ob MOSFET, P-channel thiab N-channel (Kuv tsis paub yog transistors yuav ua haujlwm), tseem kho ob qho tib si ci ntsa iab tab sis tawm tsam ib leeg. vim lub voj voog. Feem ntau, LED N-channel yuav ci dua yog tias lub luag haujlwm qis dua 50% thaum qhov kev tawm tsam MOSFET LED P-channel yuav tsaus. Tab sis yog lub luag haujlwm ua haujlwm siab dua 50%, LED P-channel yuav ci dua, tab sis LED N-channel yuav ploj, qhov no txuas ntxiv yog tias koj khaws kho nws los ntawm lub zog ntsuas, uas kho lub voj voog ua haujlwm.

Qhov no muaj txiaj ntsig zoo yog tias koj siv Cools thiab Warm White LEDs.

Cov vis dis aus yuav ua kom pom tias nws ua haujlwm li cas rau ntawm qhov taw qhia.

Kauj Ruam 1: Npaj Tshooj thiab Cov Cuab Yeej

ICs

555Timer Chip -1x

nrog 8 tus pin ntsaws -1x

MOSFET

IRFI9Z34G (P -channel) - 1x

IRFIZ34G (N -channel) -1x

Resistor

1k3x ua

1K - 2x (rau kev sim)

potentiometer 100K -1x

Diode

1 n4007 - 2x

Ceramic Capacitor

chaws -104 100nF -1x

chaws -10 -1x

Lwm tus

Purfboard (PCB)- 1x qhov loj me nyob ntawm koj.

Ntsia Hlau Terminals -3x

Jumper Hlau

LEDs rau kev sim

LEDs (koj cov LEDs uas xav siv ntawm no)

Cov cuab yeej

whiteboard (rau kev xeem)

Pliers thiab Soldering Iron

Kauj Ruam 2: Txuas rau Whiteboard thiab Xeem

(Nws yuav yog qhov zoo tshaj plaws los ntsuas nws ua ntej ua ntej siv nws ncaj qha mus rau lub purfboard)

cov txheej txheem yog saum toj no, ua raws cov kev sib txuas mus rau txhua qhov tivthaiv thiab luv nws raws li qhov ua tau los txo kev cuam tshuam yam tsis xav tau. Yog tias koj ua tiav, fais nws los ntawm 12V thiab nrhiav teeb meem.

Yog tias koj ntsib teeb meem, koj yuav tsum daws nws los ntawm,

-Txheeb xyuas kev sib txuas yog tias muaj kev sib txuas tsis raug.

-Tsis tseem muaj hwj chim, lossis rov qab txuas lub zog.

-yog siv transistors zoo li (PNP, thiab NPN).- (Nws yuav zoo dua los siv MOSFETs tam sim no.)

Yog tias koj tseem tsis tuaj yeem daws qhov teeb meem, xav tawm tswv yim hauv qab no thiab teb nws rau koj.

Thaum txhua yam ua haujlwm nws yuav tsum yog, tom qab ntawd koj tau npaj txav mus rau theem 3.

Kauj Ruam 3: Muab koj lub Circuit tso rau ntawm Purfboard

Qhov loj ntawm purfboard yuav nyob ntawm koj xaiv, Tab sis kuv pom zoo kom siv lub purfboard me dua, cov phiaj xwm tseem zoo ib yam, tab sis cov ntsia hlau txuas tau ntxiv rau lub purfboard rau kev sib txuas ntawm Lub zog tawm tswv yim, P-channel, thiab N- channel.

nco ntsoov ua kom tag nrho cov khoom sib ze kom sib ze tau.

Cov txheej txheem yuav siv sij hawm 1 teev kom tiav.

Yog tias koj ua tiav, tom qab ntawd txuas lub zog hluav taws xob thiab tshawb xyuas cov teeb meem.

Ib zaug ntxiv, Yog tias koj ntsib teeb meem, koj yuav tsum daws nws los ntawm, -Check kev sib txuas yog tias muaj kev sib txuas tsis raug.

-Tsis tseem muaj zog, lossis rov qab txuas lub zog.

-tsis muaj txoj kev soldered.

Kauj ruam 4: Tiav lawm

Nws yuav tsis zoo tag nrho, Tab sis nws ua haujlwm lawm.

Xav tias tawm tswv yim yog tias koj muaj lus nug txog qhov project.

Yog tias koj ua koj tus kheej Ob Chav LED Dimmer. thov qhia.
