Qhov kev sib tw me me no yog txoj hauv kev yooj yim los ua kom ploj mus yam tsis tas yuav muaj program chips lossis sau code. Tsuas yog ob peb yam yooj yim thiab koj npaj tau ploj mus txhua hnub. Qhov kawg tshwm sim yog qhov ploj mus tas li thiab ploj ib yam li Mac ntawm tos. Sim nws! Saib me me koj tuaj yeem tsim nws li cas. Yog tias koj nyiam nws ntsuas kuv Cov Lus Qhia. Yog tias koj tsis ua, ntsuas kuv Cov Lus Qhia.

Kauj Ruam 1: Sau Cov Cuab Yeej thiab Cov Cheeb Tsam

Rau qhov haujlwm no koj yuav xav tau:

Cov Khoom Hluav Taws Xob 470 ohm resistor (lossis tus tiv thaiv kom poob qhov tam sim no rau qhov koj xav tau coj los ntawm ib puag ncig 8 volts.) 33k resistor (lossis 100k potentiometer rau kho lub sijhawm ploj) LED (Kuv siv Xiav) 100uf Capacitor 555 Timer Generic NPN Transistor Copper clad pawg thawj coj saib. breadboard, los yog phiaj xwm phiaj xwm. Cov Cuab Yeej Dremel lossis lwm yam cuab yeej siv rau drilling 1/32 laum me ntsis rau cov xov hlau Txiav lub log lossis tin snips yog tias tsim nyog los txiav cov laug cam Cov laug cam hlau Scotchbrite ncoo lossis cov ntawv xuab zeb zoo. Hydrogen Peroxide (tus qauv ntxuav lub qhov txhab) Pom hauv cov khw muag tshuaj, khw muag khoom noj, tej zaum koj yuav muaj qee yam nyob hauv tsev. Misc Latex lossis Nitrile Gloves Acetone los ntxuav tus number case tawm ntawm lub rooj tom qab. Sab nraum zoov thaj chaw kom kos rau hauv Yas lossis lub khob iav kom muab cov tshuaj pleev rau hauv. Pab txhais tes tuav nrog iav tsom iav (zoo kom muaj tes thib peb) Kuv tau suav nrog cov ntaub ntawv rau Express PCB software. Rub tawm dawb.

Kauj ruam 2: Breadboard Nws

Tua tawm lub khob cij thiab ua raws nws.

555 Timer Pin 1- To Ground Pin 2- Jumper to Pin 6, Jumper to Base of NPN Pin 3- 33k resistor to base of NPN Pin 4- Jumper to Pin 8 Pin 5- NC Pin 6-Jumper to Pin 2 Pin 7- NC Pin 8 -Jumper rau Pin 4, Txuas nrog Qhov Zoo Tshaj Tawm Emitter ntawm NPN mus rau 470ohm resistor rau LED Base ntawm NPN rau + sab ntawm lub hau, tom qab ntawd hauv av - sab sau ntawm NPN rau + voltage

Kauj ruam 3: Pib

Txog cov laug cam no, Kuv coj kuv cov tswv yim thiab ua ntej pcb ua ntej kuv kos cov cim. Qhov no ua rau kuv hloov pauv me ntsis ntxiv thaum kos duab. Nws ua haujlwm tau zoo rau ib lub rooj tsavxwm ib sab tab sis thaum koj pib ob lub rooj sib tham, nws tuaj yeem ua teeb meem. Kuv siv lub dremel thiab 1/32 "ntsis thiab tes drilled lawv. Tsuav koj tau ceev faj thiab paub tseeb tias koj tsis driling ntawm lub kaum ntse ntse, koj tuaj yeem txhais tes laum koj lub qhov tsis zoo rau kev ntseeg nrov. Kuv paub kuv ' d ua ntau yam ntawm no yog li kuv tau siv cov ntaub ntawv pob zeb qub tawg los ntawm CD thiab siv nws los ua cov txheej txheem drilling. Rau qhov yooj yim ntawm Circuit lossis rau cov txheej txheem yooj yim dua, koj yuav saib mus rau txoj hauv kev hloov cov toner. Txhua yam koj kos rau ntawm tooj liab yuav tsis yaj los ntawm cov kua qaub. Kuv kos cov cim thiab tom qab ntawd sau tag nrho qhov "tuag qhov chaw" nrog ntau tus lej. Qhov no yog txhawm rau ua kom nrawm dua cov txheej txheem ntau dua. Cov tooj liab ntau dua uas koj tab tom ua, cov ntawv yuav siv sijhawm ntev dua.

Kauj Ruam 4: Cia Peb Tau Txais

Tam sim no koj tau txais koj cov txheej txheem sau tseg thiab koj cov Muriatic Acid thiab Peroxide, cia peb sib xyaw peb tus neeg sawv cev kos npe. Tau txais koj tus kheej lub thawv yas tawv kom nchuav cov tshuaj no rau hauv. Kuv nyiam siv lub ntim uas hais txog qhov loj ntawm lub rooj tsavxwm Kuv tab tom txiav los txiav cov tshuaj uas tsim nyog. Nqa qee cov hnab looj tes thiab muab tso rau lossis yuav raug tshuaj lom. Kuv tau txaws nws ntawm kuv tus kheej thiab nws hlawv. Sib tov ib ncig ob feem peroxide rau ib feem kua qaub rau hauv koj lub ntim. Ib txwm ntxiv cov kua qaub rau peroxide thiab nchuav cov kua qaub rau hauv ib sab ntawm lub thawv es tsis txhob txaws rau hauv nruab nrab. Qhov no yuav tsum tau txiav/tshem tawm cov txaws. Muab lub rooj tsavxwm tso rau hauv thiab maj mam ua kom cov kua nyob ib ncig ntawm lub rooj tsavxwm los ntawm kev yws nws. Cov kauj ruam no tsis tsim nyog tab sis nws yuav txiav rau lub sijhawm kos. Cov ntawv tshwj xeeb no tau siv sijhawm tsawg dua ob feeb. Lub thawv yuav kub dua yog li ceev faj heev. Nqa koj tus kheej rab diav rawg yas los tswj lub rooj tsavxwm thiab lub taub ntim dej me me kom dunk lub rooj tsavxwm tiav thaum ua tiav.

Kauj Ruam 5: Ntxuav Lub Rooj Sib Tham Etched

Lob koj cov acetone, txhuam dej cawv, lossis lwm yam tshuaj ntxhua khaub ncaws thiab tshem tawm txhua tus cim. Kuv poob kuv lub rooj tsavxwm rau hauv lub thawv me me nrog me ntsis ntawm acetone thiab yws ncig. Tus cim tsuas yog ntab tawm. Rov qab los ntawm lub rooj tsavxwm, qhuav nws tawm, thiab peb tau npaj los pib lub tshuab hluav taws xob ib sab ntawm nws. Txij ntawm no koj tuaj yeem rov ua dua/txhuam lub rooj tsavxwm yog tias koj xav ntxuav nws ntxiv thiab coj rov los ci. Nws yuav oxidize dua yog li tsis txhob siv sijhawm ntau dhau rau nws.

Kauj Ruam 6: Cia Solder

Txij ntawm no mus, koj yuav xav tua hluav taws xob thiab tshem koj cov khoom tawm.

Peb xav tau: 100uf Capacitor Blue LED 33k Resistor 470 ohm Resistor 555 Timer NPN Transistor (PNP yuav tsis ua haujlwm) Peb cov ntawv tshiab uas tau sau tas tas yog qhov yooj yim. Muab cov khoom sib dhos ua kom ntseeg tau tias muaj kev sib haum xeeb. Tus pin sab laug sab saum toj nrog lub voj voos nyob ib sab ntawm nws yog tus pin ntawm 555 timer. Ob lub capacitor thiab LED muaj ib txoj hauv kev ntev thiab ib txoj hauv kev luv. Cov hlau lead ntev yog lub cim uas yog sab zoo thiab cov cathode yog sab luv. Thawb cov coj los ntawm lub qhov thiab khoov lawv me ntsis ntawm lwm sab kom tiv thaiv lawv kom tsis txhob poob tawm. Tshem tawm thiab tshem nws. Tos … Kuv tsis nco qab ntxiv qhov rau cov xov hluav taws xob. Qhov tseeb kuv tsuas yog hnov qab laum lawv. Nqa koj lub roj teeb 9v thiab siv qhov zoo rau tus pin 8 thiab qhov tsis zoo rau tus pin 1. Tom qab ob peb feeb cov LED yuav tsum ploj mus, tuav, thiab tom qab ntawd ploj mus. Lather, yaug, rov ua dua.https://www.youtube.com/watch? V = o9f3BoPnGu0

Kauj ruam 7: Ua tau

Koj tuaj yeem txuas ntawm cov xov hlau rau lub davhlau ya nyob twg roj teeb thiab txuas raws li koj xav tau. Los yog ntxiv qhov hloov pauv thiab qhib nws ntawm koj qhov kev txiav txim siab. Txheeb tawm cov vis dis aus luv ntawm no.https://www.youtube.com/watch? V = o9f3BoPnGu0 Kuv yuav sim ua kom tau txais cov phiaj xwm sai sai. Cov khoom siv rau cov lus qhia no
