Puas yog nws tshwm sim rau koj txhua lub sijhawm uas koj tau ua ib qhov haujlwm thiab nws tsis ua haujlwm vim yog cov transistors tsis raug lossis ua tsis raug. Yog li ntawm no yog cov cuab yeej uas koj tuaj yeem ntsuas cov khoom xws li transistor, diodes, LDR, LED, thiab lwm yam ua ntej pib qhov project. Nws yog compact thiab tsav los ntawm npib cell.
Xeem Cheeb Tsam Zoo li LED siv Multi meter yog qhov tsis meej. Txawm li cas los xij koj tsis tuaj yeem ntsuas Cheebtsam zoo li Capacitor, Yog Transistor NPN lossis PNP, thiab lwm yam. Tsuas yog ntsaws lawv thiab pom cov txiaj ntsig. Cov lus qhia tshwj xeeb ntawm TESTERA yog raws li hauv qab no:
Handy Device thiab tuaj yeem nqa tau yooj yim
Tau dai nws ntawm phab ntsa Cov Cuab Yeej
Muaj peev xwm txheeb xyuas NPN lossis PNP Transistors
LED Qhia
Ib qho yooj yim rau Plug Cheebtsam
Roj Teeb Ntev
Hnab Hnab Loj
Kauj Ruam 1: Xeem LED
Nov yog daim duab qhia kev ntsuas rau kev ntsuas LED. Thaum koj nias qhov hloov pauv, lub Circuit Court tau txuas nrog thiab LED ci yog tias nws ua haujlwm.
Peb tab tom ua nrog kev pab tsuas yog ib lub roj teeb, yog li txuas tag nrho cov kab ke uas tab tom ua ntej nrog ib lub roj teeb!
Kuj tseem tuaj yeem siv los ntsuas IR coj.
Kauj Ruam 2: Kuaj Transistor
Ua raws daim duab qhia kev ntsuas ntsuas transistor. Nov yog siv cov kab hluav taws xob no koj tuaj yeem tshawb xyuas seb lub transistor yog PNP lossis NPN. Yog tias Tus Sau thiab Lub hauv paus ntawm transistor luv, tom qab ntawd nws yog NPN txwv tsis pub transistor hauv kev sim yog PNP.
LED nyob ntawd los qhia qhov qhia seb nws yog NPN lossis PNP.
Kauj Ruam 3: Xeem Lwm Cov Cheeb Tsam
Ua raws daim duab qhia chaw txhawm rau ntsuas lwm yam khoom xws li LDR, Capacitor, diode, qaij cov ntsuas, thiab lwm yam.
Kauj ruam 4: Siv Nws
Txhawm rau txheeb xyuas LED:
Tsuas yog ntsaws LED rau hauv ntu LED thiab Nias Lub Pob. Koj yuav pom LED Glowing thiab yog tias tsis LED tsis ua haujlwm. Yooj yim txaus !! Ntxiv mus koj tseem tuaj yeem ntsuas IR LED tab sis rau qhov uas koj xav tau Lub Koob Yees Duab.
Nco ntsoov Txheeb Xyuas Polarity!
Txhawm rau Txheeb Xyuas Transistor:
Txheeb xyuas seb Transistor yog NPN lossis PNP. Txuas lub Transistor hauv Kev Txiav Txim ntawm CBE thiab yog tias LED Glows, Transistor yog NPN lossis lwm qhov PNP Transistor.
Txheeb Xyuas Lwm Yam Cheeb Tsam:
Txhawm rau txheeb xyuas lwm yam Cheeb Tsam, Txuas Bipolar Cheeb Tsam hauv Cheeb Tsam Kuaj thiab Ua Raws Cov Lus:
Kev Qhia Cuam Tshuam
Capacitor: LED ci ci thiab tom qab Dims
Diode: Glows Thaum Txuas Nrog Rau Qhov Tsis Ncaj Ncees
Resistor: Glows Raws Li Kev Tiv Thaiv ntawm Resistor
Tilt Sensor: Glows thiab thaum qaij rov qab
LDR: LED ci raws li teeb pom kev ntawm LDR
Zoo li qhov no Koj tuaj yeem Ntsuam Xyuas Feem Ntau Yam.
Kauj ruam 5: Tsaug
Tam sim no, tsuas yog muab tag nrho cov kab ke hauv ib lub thawv thiab nws tau npaj ua haujlwm!
Ua tsaug rau koj los ntawm!
