H-Choj yog lub voj voos uas tuaj yeem tsav DC lub cav rau pem hauv ntej thiab thim rov qab. Lub zog taw qhia tau hloov pauv los ntawm kev hloov pauv qhov sib txawv ntawm qhov hluav taws xob txhawm rau tig lub cav ib txoj kev lossis lwm qhov. Qhov no tau qhia tau yooj yim los ntawm kev siv lub roj teeb 9-volt rau cov coj ntawm lub cav me me thiab tom qab ntawd hloov lub dav hlau kom hloov cov lus qhia. H-Choj tau muab nws lub npe raws li qhov yooj yim Circuit Court uas qhia tau tias nws ua haujlwm li cas. Qhov Circuit no muaj plaub qhov hloov pauv uas ua tiav qhov Circuit thaum siv ua khub. Thaum cov hloov pauv S1 thiab S4 raug kaw lub cav tau txais lub zog thiab tig. Thaum S2 thiab S3 raug kaw lub cav tau txais lub zog thiab tig mus rau lwm qhov. Nco ntsoov tias S1 thiab S2 lossis S3 thiab S4 yuav tsum tsis txhob raug kaw ua ke kom tsis txhob muaj qhov luv luv. Kuv pom tau tias lub cev hloov pauv tsis ua haujlwm vim tias tsis muaj leej twg yuav zaum zaum tig lub qhov muag hloov ua khub kom lawv cov neeg hlau txav mus rau tom ntej lossis rov qab. Qhov ntawd yog qhov uas cov transistors nkag los. Qhov transistor ua raws li lub xeev hloov pauv uas kaw thaum qhov me me tam sim no tau siv rau nws lub hauv paus. Vim tias tsuas yog ib qho me me tam sim no yuav tsum tau qhib lub transistor peb tuaj yeem ua tiav ib nrab ntawm Circuit Court nrog ib lub teeb liab. Qhov ntawd yog qhov kev xav txaus los pib yog li cia peb pib tsim.

Peb yuav pib los ntawm kev teeb tsa cov kab hluav taws xob. Txuas koj lub roj teeb ntsaws rau ib ces kaum ntawm lub tsheb npav fais fab. Qhov kev pom zoo yog txhawm rau txuas qhov hluav taws xob zoo mus rau kab sab saud thiab qhov tsis zoo rau kab hauv qab kom qhia txog HIGH thiab LOW cov cim qhia feem. Tom qab ntawd peb txuas cov txheej txheem sab saum toj thiab hauv qab ntawm cov tsheb npav fais fab.

Cov kauj ruam tom ntej yog teeb tsa cov transistors. Rov qab rau hauv ntu kev xav uas peb xav tau plaub tus hloov pauv los tsim H-Choj, yog li peb yuav siv tag nrho plaub lub transistors ntawm no. Peb kuj tseem txwv rau qhov teeb tsa ntawm lub khob cij kom lub Circuit Court tiag tiag yuav tsis zoo ib yam li tsab ntawv H. Lus saib nrawm ntawm lub transistor kom nkag siab txog qhov ntws tam sim no. Muaj peb ceg ntawm txhua tus transistor hu ua tus sau, hauv paus, thiab tus xa tawm. Tsis yog txhua tus transistors sib koom ib qho kev txiav txim yog li nco ntsoov tham nrog cov ntaub ntawv yog tias koj tsis siv ib qho ntawm cov lej tau hais hauv qib ib. Thaum twg ib qho me me tam sim no tau thov rau lub hauv paus, lwm qhov loj dua tam sim no tau tso cai los ntawm cov neeg sau khoom tus xa tawm Qhov tseem ceeb yog li kuv yuav rov hais dua. Lub transistor tso cai rau me me tam sim no los tswj qhov loj dua tam sim no. Hauv qhov no tus emitter yuav tsum txuas nrog hauv av ib txwm. Nco ntsoov tias cov dej ntws tam sim no sawv cev los ntawm tus xub me me hauv daim duab hauv qab no.

Tam sim no peb tab tom ua kab ntawm cov transistors hauv qab ib nrab ntawm lub khob cij, tig qhov kev taw qhia rau txhua lwm transistor. Txhua khub ntawm cov transistors nyob ib sab yuav ua ib nrab ntawm H-Choj. Ib qhov chaw txaus yuav tsum tau sab laug nyob rau hauv nruab nrab txhawm rau kom haum rau qee tus dhia thiab thaum kawg lub cev muaj zog. Tom ntej no peb yuav txuas cov transistors 'tus neeg khaws thiab tso tawm mus rau lub tsheb npav zoo thiab tsis zoo. Thaum kawg peb yuav ntxiv cov jumpers uas yuav txuas rau lub cav ua haujlwm. Lub transistors tam sim no npaj kom dhau qhov tam sim no thaum lub hauv paus tau qhib.

Peb yuav tsum tau siv qhov me me tam sim no rau txhua tus transistors ua khub. Ua ntej peb yuav tsum tau txuas tus resistor rau txhua tus transistor lub hauv paus. Ntawm no peb yuav txuas txhua pawg ntawm cov resistors mus rau ib qho taw tes hauv kev npaj los txuas qhov hloov pauv. Cov keyboards no yuav qhib ib nrab ntawm H-Choj ib zaug thiab thaum kawg peb txuas lub cav. Qhov ntawd yog nws. Txuas koj lub roj teeb thiab ntsuas koj lub Circuit Court. Lub cev muaj zog yuav tsum tig ib qho kev taw qhia thaum ib lub pob raug thawb thiab cov lus qhia rov qab thaum lwm lub pob raug thawb. Ob lub khawm yuav tsum tsis txhob qhib rau tib lub sijhawm.
