Lub Hom Phiaj
Cov lus qhia no yog tsom mus rau cov tib neeg uas txaus siab rau cov khoom siv hluav taws xob (nrog keeb kwm yav dhau los me ntsis) uas tab tom nrhiav kev ua si yooj yim uas koj tuaj yeem tsim nrog tsuas yog qee qhov pheej yig.
Qib Nyuaj
Qhov no yuav nyuaj yog tias koj muaj kev paub me me lossis tsis paub txog daim duab kos duab, tab sis kuv sim ua kom muaj txiaj ntsig zoo li kuv tuaj yeem ua raws txoj hauv kev yog li koj yuav tsis xav tau saib daim duab saum toj no (los ntawm 555 Timer Circuit)! Tsis muaj kev siv tshuaj yaj yeeb yuav siv rau hauv cov lus qhia no, txawm hais tias koj tuaj yeem siv cov kab hluav taws xob no ua ke ntawm koj tus kheej yog tias koj xav tau.
Yam Koj Yuav Xav Tau (txuas mus yuav khoom yog nyob ntawm cov npe ntawm txhua qhov no)
- Ib daim ntawv qhia zaub mov. Qhov no yog qhov tseem ceeb rau kev tsim peb lub Circuit Court yam tsis muaj qhov yuav tsum tau siv.
- Qee cov xov hlau los txuas peb cov khoom siv. Tej zaum yuav zoo kom muaj ob peb qhov sib txawv ntawm 2-6 ntiv tes
- 6V Voltage Source - Kuv tau siv qhov no nrog rau 4 tus qauv AA roj teeb. Cov tinned ua rau nws yog li peb tuaj yeem ntsaws nws rau hauv lub khob cij.
- 555 Timer - Qhov no yog kev sib xyaw ua ke (IC) siv ntau lub sijhawm lossis oscillatory circuits. Qhov no ua haujlwm rau peb ncua sijhawm.
- 7 Segment Display - Nov yog qhov kuv tau siv, tab sis muaj ntau qhov sib txawv uas zoo ib yam
- CD4026B Counter IC - Qhov no yuav txuas rau 7 ntu tso saib thiab 555 timer thiab qhia rau ntu twg kom pom kev thaum twg.
- 2 Khawm Me Kom pib lossis nres lub sijhawm
- 3 10uF Capacitors
- Ib qho 1nF Capacitor
- Ib leeg 68k ohm resistor
- 3 100k ohm resistors
Kauj Ruam 1: Thawj Kauj Ruam
Ua ntej peb yuav tsum tau sau tag nrho peb cov khoom siv, tso lawv tawm kom zoo, thiab tso peb thawj ob peb yam ntawm lub khob cij. Kuv tau npaj kuv cov khoom pib ua li no rau (vam tias) qhov kev pom zoo tshaj plaws ntawm lwm cov khoom nyob ib puag ncig lawv. Los ntawm sab saum toj mus rau hauv qab: 7 ntu tso saib, cd4026be, ne555, tom qab ntawd pib thiab nres khawm.
Kauj Ruam 2: Kev sib txuas rau Voltage hauv thiab hauv av
Peb yuav siv cov + thiab - cov kab sib txuas ntawm sab laug ntawm peb lub khob cij ua kom muaj kev sib txuas rau hauv av (cov roj teeb dub) thiab Voltage Hauv (xov tooj liab liab)
Kauj Ruam 3: Lwm Yam Kev Sib Txuas Ntawm Cov Khawm thiab ICs
Okay, tam sim no peb yuav ua tiav qhov seem ntawm kev sib txuas uas tsis yog rau Xya Segment Display. Qhov no suav nrog cov xov hlau txuas cov nyees khawm mus rau qhov seem hauv Circuit Court, thiab kev sib txuas ntawm 555 timer thiab 4026 txee.
Kauj Ruam 4: Ua tiav Kev Sib Txuas rau 7 Segment Display
Tom qab ntawd peb tsuas yog xav tau kom phim tus lej cim ntawm 4026 IC thiab 7 Segment Display. Cov lus sib txawv tuaj yeem muaj tus pin hauv kev xaj sib txawv lossis txoj haujlwm, yog li koj yuav tsum tau sab laj koj cov duab tshwj xeeb cov duab. Nov yog ob qho kev teeb tsa ib txwm muaj, txawm hais tias. (daim ntawv qhia ntawm tsab ntawv mus rau txoj haujlwm ntawm lub vijtsam ib txwm zoo ib yam txawm hais tias, ex. "a" ib txwm yog kab saum toj kawg nkaus, "g" ib txwm yog kab nruab nrab, thiab lwm yam.) Tsis tas yuav muab tus lej lej zauv cim.
Kauj ruam 5: Ua si
Thaum koj nias lub pob pib, nws yuav ua rau ne555 pib thiab tshem tawm txhua yam uas twb muaj lawm hauv 4026 lub txee. Ne555 yuav xa cov pa taws mus rau 4026 lub txee ntawm qhov zaus ntawm 0.1 Hz uas yuav hloov tus lej tso tawm ntawm 7 ntu saib.
Thaum koj nias lub pob nres, nws yuav khov cov zaub kom koj pom nws!
