Polarity Pen Tester - Ib qho yooj yim dua

Qhov no yog qhov yooj yim aveter polarity tester rau kev ntsuas tshuab hauv tshuab thiab tseem rau cov khoom siv hluav taws xob.

Lub Circuit Court yog qhov yooj yim heev nrog rau nws txoj haujlwm. LED daj qhia tau yog tias tus cwj mem txuas nrog lub hwj chim. Ib lub LED liab qhia thaum qhov kev sojntsuam tau txuas nrog cov hlau lead zoo hauv qhov ntsuas. Ib lub ntsuab ntsuab qhia thaum qhov kev sojntsuam tau txuas nrog rau qhov tsis zoo lossis lub ntiaj teb hauv qhov ntsuas.

Tau kawg, koj tuaj yeem hloov pauv cov hlua raws li koj "saj" …

Tus hmuv dub thiab liab liab txuas rau lub zog dav dav (koj kuj tseem tuaj yeem siv tus pin txiv tsawb los ua nws. Tus txiv neej tus txiv tsawb tus pin nrog tus taw tes me me txuas rau qhov ntsuas pom tseeb hauv PCB tau suav nrog hauv txoj haujlwm.

Cov teeb tau teeb tsa siv tus cwj mem pemanent. Cov qhov tau raug drilled rau LEDs. Cov xaim siv rau tus nab kaws tau raug tshem tawm ntawm lub dab teg los tiv thaiv zoo li qub (lawv yoog tau yooj yim heev). Cov nab kuab txuas nrog cov txiv tsawb pins….

Hauv cov kauj ruam tom ntej koj yuav pom txhua cov ntaub ntawv koj xav tau los tsim txoj haujlwm.

Kauj ruam 1: Schematic thiab Cheebtsam

Hauv Daim Duab koj tuaj yeem pom cov txheej txheem, nws yooj yim heev los tsim nws

Cov khoom koj yuav xav tau yog:

3 x 1K5 (resistor);

3 x LED (5 hli);

2 x tus nab kaws (dub thiab liab);

3 x txiv neej txiv tsawb pin;

1 x txuas ntxiv rau txiv tsawb tus pin nrog cov ntsiab lus zoo (xaiv tau);

1 x cwj mem tas mus li (siv);

1 x tooj liab PCB

1 x siv tus cwj mem tas mus li los yog witheboards marker tube;

Cov xov hlau yooj ywm;

Cov cuab yeej;

Kauj Ruam 2: PCB thiab Cov Txheej Txheem Npaj

Koj yuav tsum tau khawb tooj liab PCB raws li qhia hauv daim duab.

Saib xyuas vim qhov pom yog los ntawm cov khoom sab hauv yog li koj yuav tsum tau thim qhov kos duab.

Lub Circuit Court ua haujlwm los ntawm 5V txog 15V

PAD1 txuas nrog POSITIVE Power Supply. PAD2 txuas nrog NEGATIVE Power Supply.

Thiab PAD3 yog TEST LEAD (PROBE)

LED3 Qhia yog tias lub hwj huam txuas nrog;

LED2 Qhia yog tias qhov kev xeem txhuas tau txuas nrog qhov zoo;

LED1 Qhia yog tias qhov kev xeem txhuas tau txuas nrog qhov tsis zoo

Kuv thov txim tab sis cov vis dis aus yog kuv hom lus "Portuguese"

Txhua qhov kev pab koj xav tau siv kuv cov neeg sib tham tau qhia hauv cov kauj ruam tom ntej.

Ua tsaug ntau ntau

Txais tos los ntawm Brazil rau txhua tus neeg thoob ntiaj teb.
