Nov yog lub khoos phis tawj me me ntawm daim duab-thav duab uas tau tsim tawm tsuas yog ntawm lub thawv ntawv khoob thiab qee cov ntawv pov tseg pov tseg. Txoj haujlwm no tseem tuaj yeem tsim los tsim cov duab loj-loj nrog tib lub vojvoog nyob hauv nws. Lub Circuit Court tsis siv microcontroller uas txo qis kev siv zog los tsim ib qho kev sib cais rau nws

Cov teeb nyob hauv Circuit Court raug tswj los ntawm qhov tsis txaus ntseeg lub npe hu ua 'Astable Multivibrator' siv ob lub transistors.

Rau tsuas yog ib lub tswv yim- tus neeg siv ntau lub astable muab qhov hluav taws xob tso tawm raws li cov laj thawj HIGH (5 Volts lossis ib qho zoo voltage) rau qee lub sijhawm thiab tom qab ntawd hloov cov zis rau logic LOW (0 volts), thiab cov txheej txheem no tshwm sim ib ntus kom txog thaum lub kaw lus raug kaw (lossis lub roj teeb tuag!).

Qhov kev siv hluav taws xob no siv qhov tseeb tias thaum qhov tso tawm siab, ob ntawm LEDs yuav ci (ntawm no ib qho liab thiab ib qho ntsuab ntawm ob sab ntawm tus ncej) thiab thaum cov zis LOW so ob LEDs yuav ci.

Cov Ntaub Ntawv Yuav Tsum Tau:

• Matchbox (txhua qhov loj me)
• 3mm LED x4 (ntawm ib qho xim)
• swb swb
• Ua Npuas Ncauj
• Ib nrab ntawm cov ntawv me me A4
• Perfboard (zero board)
• 3V khawm cell thiab nws tus tuav
• 2 Transistors BC547 lossis 2N2222 (ib qho npn zoo ib yam transistors yuav txaus)
• Resistors: 2pc 220ohm, 2pc 100ohm, 2pc 47k ohm
• Capacitors: 2pc ntawm 10uF- (35v lossis tsawg dua) (qhov siab yuav tsum qis vim nws tuaj yeem haum hauv lub thawv ntawv sib tw).
• ib leeg strand jumper xov hlau
• cov hlau txuas thiab cov hlau txuas

(Qhov ntsuas tus nqi tau txheeb xyuas los ntawm nws cov xim xim, kom paub meej ntxiv, xa mus ntawm no:

Kauj Ruam 1: Lub Plawv - Circuitry

Cov duab thav duab yuav tsum tau ua raws li qhov loj ntawm lub thawv ntawv sib tw.

Thawj daim duab yog lub hauv paus pib ntawm Astable Multivibrator. Kuv tau hloov kho Circuit kom kho lub teeb thiab hloov raws li qhov xav tau, raws li qhia hauv daim duab thib ob.

Tam sim no muab cov khoom tso rau ntawm daim phiaj raws li daim duab qhia chaw hauv daim duab thib ob, siv thaj tsam tsawg kawg rau nws kom nws haum rau sab hauv lub thawv ntawv yam tsis muaj teeb meem ntau. Hauv theem no, kev teeb tsa ntawm cov khoom sib txawv ntawm ib tus neeg mus rau lwm tus tsuav yog kev sib txuas raug.

Kev tso chaw ntawm LEDs:

Cov LEDs uas yog RED1 & GREEN1 yuav tsum tau muab tso rau ntawm cov ntug sib txawv thiab RED2 & Green2 ntawm ob seem ntxiv. Saib pic3 saum toj no.

Nco ntsoov tias qhov hloov pauv tau muab tso rau xws li nws tawm ntawm lub perfboard, zoo li thaum kawg qhov kev hloov pauv yuav raug tswj thaum lub qib muaj nyob sab nraum tus ncej.

Kauj Ruam 2: Kuaj Phaj

Cov xov hlau ntawm LEDs tuaj yeem txuas ntxiv ntev txaus kom cov LEDs tau yooj yim kho nyob ib puag ncig ntawm ntug ntawm lub thawv ntawv sib tw.

Txiav lub perfboard raws li qhov loj ntawm Circuit Court thiab muab tso rau hauv lub thawv ntawv sib tw. Sau qhov seem ntawm lub thawv ntawv sib tw nrog ua npuas dej rau lub cev ruaj khov. Ua kab noj hniav rau tus tuav lub xovtooj ntawm tes, yog tias koj muaj lub roj teeb tuav nws yuav nkag mus rau hauv kab noj hniav no. Kuv tsis muaj nws yog li kuv tau muab cov ntawv txhuas daim kab xev tso rau ntawm ob sab kawg ntawm kab noj hniav thiab muab nws txuas nrog cov xov hlau txuas rau txuas.

Luag tag nrho cov kev txuas ntawm perfboard. Nco ntsoov tias cov xov hlau tsis luv.

Kauj Ruam 3: Npog Txhua Qhov

Muab tso rau hauv lub roj teeb ces qhib ib sab ntawm lub thawv ntawv sib tw thiab npog lub Circuit Court. Cov ceg ntawm LED yuav tsum nyob sab nraum lub hau. Nws yuav tau npog los ntawm daim ntawv xim tom qab.

Txoj haujlwm yuav luag tiav ntawm no.

Kauj Ruam 4: Kho kom zoo

Siv cov ntawv los yog tawv ua npuas ncauj thiab txiav tawm ib daim duab plaub (lossis ib qho zoo li koj xaiv, tab sis nws yuav tsum loj txaus los npog qhov ntev ntawm lub thawv ntawv sib dhos) txhawm rau txhim kho nws hla lub thawv ntawv sib tw. Ua qhov me me los ntawm nws kom LED tuaj yeem tawm ntawm nws. Koj tuaj yeem muab kev kos duab tsim rau nws.

Npog ob sab thiab lub hauv paus ntawm lub npov nrog kab txaij ntev ntawm daim ntawv xim (Kuv xaiv xiav) los ntawm qhov cua nws hla ob sab. Kos rau txoj haujlwm ntawm Hloov qib. Txiav tawm qhov feem ntau ntawm qhov hloov pauv kom cov kab txaij npog sab. Koj tseem tuaj yeem tshawb nrhiav 'Net of a cuboid' thiab tsim tib yam los npog lub hauv paus thiab sab ntawm lub thawv ntawv sib tw hauv ib qho.

Tam sim no pleev xim nws lossis kos duab tsim los muab nws saib zoo.

Tam sim no muab ib daim duab zoo thiab Qhib qhov hloov. Muaj Kev Lom Zem !!

(Koj tuaj yeem tsim tib daim duab thav duab nrog ntau tus lej LEDs txhawm rau sau ciam teb)
