Ua tus tivthaiv yooj yim thiab ntsuas ntsuas txuas ntxiv. Qhov no yog siv los ntsuas cov kab hluav taws xob thiab cov khoom siv hluav taws xob los saib seb lawv puas ua haujlwm.

Kauj Ruam 1: Yam Koj Yuav Tsum Tau

Koj yuav xav tau dab tsi

1 x 3 los ntawm 8 qhov kab txaij board 1 x 390ohm resistor 1 x LED (xim twg) Soldering Hlau (nrog cov laug ntawm chav kawm) 2 x Crocodile/Aligator clips 1 x PP3 Roj Teeb Txuas (Kuv coj kuv los ntawm lub qub PP3 roj teeb) Cov xim xaim np. ntsuab & liab/xiav & liab thiab lwm yam 3-5 hli laum kom tawg tooj liab hauv pawg thawj coj saib

Kauj ruam 2: Tsim Circuit Court

Pib los ntawm kev tawg tooj liab raws li kuv tau ua hauv daim duab. Tom qab ntawd tso thiab muab cov xov hlau zoo tso rau ntawm lub roj teeb thiab cov khej/cov nab kuab tso rau ntawm kab txaij nrog cov kab tawg raws li kuv tau ua. Tom qab ntawd pib los ntawm kev tso 390ohm resistor tawm hauv qhov tawg ntawm tooj liab ntawm ob txoj hauv kev ntawm txoj kab tawg (ib sab ntawm lub roj teeb clip) thiab muab nws tso rau hauv. crocodile clip) thiab muab nws tso rau hauv qhov tawg ntawm tooj liab ntawm ob txoj hauv kev.

Kauj Ruam 3: Txuas Nws

Txhua yam uas tseem tshuav los ua tam sim no yog txuas nws mus rau 9v PP3 roj teeb thiab txuas cov ntu txuas rau ib feem lossis hauv Circuit Court uas koj yuav mus sim. Yog tias koj tab tom ntsuas ib qho LED ob qho tib si LEDs yuav ci ntsa iab. *Nco tseg yog tias koj tab tom ntsuas lub ntsuas hluav taws xob nco ntsoov txuas nws nrog qhov ua kom raug lossis koj yuav pheej hmoo koj lub peev xwm lub neej.

Resistors LED ci rau kev tiv thaiv qis, tsawg dua li 1k. LED dim rau nruab nrab tiv taus, ob peb k. LED tawm rau kev tiv thaiv siab, ntau dua li 10k. Diodes LED ci nrog cov xim liab ua rau anode thiab dub ua rau cathode (kab txaij). LED tawm nrog cov xim dub ua rau anode thiab liab ua rau cathode (kab txaij). Zener Diodes LED ci nrog xim liab ua rau anode thiab dub ua rau cathode (kab txaij). LED dim nrog cov xim dub ua rau anode thiab liab ua rau cathode (kab txaij) yog zener diode voltage tsawg dua li 7V. LED tawm nrog cov xim dub ua rau anode thiab liab ua rau cathode (kab txaij) yog zener diode qhov hluav taws xob ntau dua li ntawm 7V Transistors Rau txhua khub ntawm transistor ua txuas tus tester ua thawj txoj hauv kev, tom qab ntawd lwm txoj kev. Nov yog cov txiaj ntsig rau NPN transistor hauv qhov xwm txheej zoo: CE khub: LED tawm ntawm ob txoj kev. BC khub: LED ci nrog xim liab ntawm B, LED tawm ntawm lwm txoj kev. Ua khub: LED ci nrog cov xim liab liab ntawm B, LED tawm ntawm lwm txoj kev. Nov yog cov txiaj ntsig rau PNP transistor nyob rau hauv zoo: CE khub: LED tawm ntawm ob txoj kev. BC khub: LED ci nrog cov xim dub ntawm B, LED tawm ntawm lwm txoj kev. Ua khub: LED ci nrog cov hmoov txhuas dub ntawm B, LED tawm ntawm lwm txoj kev.
