LED snowman rau txhua tus

Nws yog ib qho nyuaj rau xav txog lub caij ntuj no tsis muaj daus. Thiab nws tseem nyuaj dua - tsis muaj snowman. Yog li ntawd, thaum peb tab tom tos kom muaj daus ntau, peb xav ua Snowman los ntawm LEDs.

Sculpting ib tug snowman yog lub cim ntawm lub caij ntuj no, tab sis rau ntau ntawm peb nws yog txuam nrog rau yav tom ntej hnub so, tsev neeg sib sau ua ke thiab dai kom zoo nkauj tsob ntoo Christmas, uas koj muaj peev xwm dai ib tug pub dawb gadget raws li ib tug ntawm cov decorations. Nws kuj tseem tuaj yeem yog ib qho khoom plig zoo rau menyuam yaus uas peb xav ua kom muaj "cov kab laum hluav taws xob". Cov snowman nthuav tawm muaj lub ntsej muag ntxim hlub, yog li nws yuav nyiam nws.

Qhov tsis muaj ib qho kev sib txuas ua ke ua rau cov teeb pom kev zoo tshaj plaws rau cov pib tshiab electronics engineers. Txawm li cas los xij, tsis muaj dab tsi tiv thaiv cov txwj laus los ntawm kev sau cov neeg ntxim hlub, me ntsis caricatured snowman, xav tias nws yog kev lom zem hauv lawv lub sijhawm dawb los ntawm kev ua haujlwm txhua hnub.

Kev piav qhia ntawm qhov layout

Daim duab kos duab yooj yim tsis tshua muaj tuaj yeem pom ntawm duab 1. Nws tsuas muaj ib txoj hlua ntawm plaub lub teeb ci LED txuas nrog rau tib lub sijhawm, uas lub zog hluav taws xob txuas nrog hauv daim ntawv ntawm ob lub roj teeb 1,5V.

1. Schematic daim duab ntawm LED snowman

Rau kev ua tiav ntawm kev ua haujlwm, muaj qhov hloov SW1 hauv lub zog hluav taws xob. Lub blinking LED, ntxiv rau qhov tsim teeb pom kev zoo, muaj qhov ua haujlwm me me hauv kev tswj hwm, yog li nws tuaj yeem (thiab yuav tsum) tau siv hluav taws xob ncaj qha, hla lub resistor uas txwv nws tam sim no. Flashing LEDs tuaj yeem lees paub los ntawm qhov chaw tsaus nti hauv rooj plaub, uas pom meej meej ntawm yees duab 1. Vim qhov sib txawv tseem ceeb hauv qhov tsis sib xws ntawm lub tshuab hluav taws xob ntawm cov LEDs no, txhua tus ntawm lawv yuav flash ntawm qhov sib txawv, tshwj xeeb zaus. Qhov no zaus yog nyob rau hauv thaj tsam ntawm 1,5-3 Hz thiab feem ntau nyob ntawm cov khoom siv hluav taws xob. LED1 yog liab thiab ua raws li ib tug snowman lub "carrot" qhov ntswg, nyob rau hauv cov ntaub ntawv no me ntsis cartoonish. Hloov cov nyees khawm dub "coal" ntawm lub plab - peb lub teeb xiav LED 2 ... 4.

Kev txhim kho thiab kho

PCB qauv suav nrog duab 2. Nws tsis tas yuav muaj kev txawj tshwj xeeb los sib sau ua ke.

Kev ua haujlwm yuav tsum pib los ntawm kev hloov pauv SW1. Nws yog tsim rau nto mounting (SMD) tab sis qhov no yuav tsum tsis txhob muaj teeb meem txawm rau cov tshiab rau electronics.

Txhawm rau ua kom yooj yim dua, muab cov tin tso rau ntawm ib qho ntawm rau SW1 cov ntsiab lus ntawm cov solder, tom qab ntawd siv cov tweezers tso lub pob rau hauv nws qhov chaw thiab yaj cov khoom siv yav dhau los nrog cov hlau soldering. Ib qho kev hloov uas npaj rau hauv txoj kev no yuav tsis txav mus, tso cai rau koj kom yooj yim solder nws lwm cov hlau lead.

Cov theem tom ntej ntawm kev sib dhos yog soldering cov LEDs. Nyob rau sab solder ntawm lub rooj tsavxwm muaj lawv cov qauv - nws yuav tsum sib haum mus rau lub cutout ntawm lub diode tso rau hauv lub mounting qhov.

Txhawm rau ntxiv qhov tseeb rau peb tus cwj pwm "snowy", nws tsim nyog ua tus pas txhuam hniav rau nws, uas tuaj yeem txuas tau zoo los ntawm cov nyiaj phaj nrog rau hauv cov khoom siv thiab soldered rau ib qho ntawm cov tinned teb raws cov npoo ntawm lub rooj tsav xwm luam tawm. . Ib tug version ntawm tus broom thiab nws qhov chaw ntawm lub phaj yog nyob rau yees duab 2.

Raws li cov khoom kawg, nplaum lub pob tawb roj teeb nrog cov nplaum nplaum rau hauv qab, thiab tom qab ntawd solder cov xaim liab mus rau BAT + teb, thiab cov xaim dub rau BAT- teb, tom qab luv lawv mus rau qhov ntev kom lawv tsis txhob protrude. dhau ntawm cov qauv ntawm peb cov snowman. Tam sim no - nco ntsoov lub polarity, uas yog cim rau ntawm lub pob tawb roj teeb - peb tso ob lub AAA hlwb (R03), lub npe hu. ntiv tes me me.

Cov tsos ntawm lub rooj sib txoos snowman sawv cev duab 3. Yog tias peb txav mus rau lub taub hau ntawm peb cov khoom ua si, cov LEDs yuav qhib. Yog tias cov duab sib sau ua ke muaj qhov nyiam poob, luv luv ntawm cov khoom siv nyiaj tuaj yeem raug soldered rau cov ntsiab lus ntawm nws lub hauv paus los ua kev txhawb nqa.

Txhawm rau kom yooj yim rau dai lub snowman, muaj ib lub qhov me me hauv lub tog raj kheej rau ntxig cov hlau los yog xov.

Peb kuj pom zoo kom ib tug tutorial video .

AVT3150 - LED snowman rau txhua tus

Txhua qhov tsim nyog rau txoj haujlwm no suav nrog hauv AVT3150 cov khoom siv muaj nyob ntawm: ntawm tus nqi txhawb 15 PAB
