Taw qhia:

Cov khoom ua si hu ua Hitting moles nrog lub mallet muaj lub rooj tsavxwm nrog tsib lub qhov nyob rau saum nws thiab lub thoob. Txhua lub qhov muaj ib lub yas yas thiab cov tshuab tsim nyog txav nws nce thiab nqis. Thaum qhov kev ua si pib, cov moles yuav pib nyem rau ntawm qhov tsis sib xws. Lub hom phiaj ntawm qhov kev ua si yog txhawm rau tsoo tus tib neeg cov moles thaum lawv nyem ncaj qha rau ntawm lub taub hau nrog lub thoob, yog li ntxiv rau tus neeg ua si cov qhab nia. Qhov sai dua qhov no yog ua tiav qhov siab dua qhov qhab nia kawg yuav yog.

Hauv qhov thaiv kab lus kab lus no tau txais los ntawm cov khoom ntaus nrig mus rau khawm (Hloov). Qhov kev hloov pauv no txuas nrog NAND lub rooj vag nrog rau cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob uas ua rau lub tswv yim thib ob rau NAND rooj vag. Ntawm no NAND rooj vag tau siv vim hais tias lub rooj sib tham yuav tsum muaj lub moos qis rau UP-counter.

Ob qhov kev hloov pauv thiab LED flashed yuav tsum yog siab los ua kom lub moos qis qis ntawm qhov tso tawm ntawm NAND rooj vag.

Los ntawm kev txuas cov diode no, D1 nruab nrab ntawm cov lus tawm tswv yim thiab cov lus tso tawm, lub sijhawm ntsuas hluav taws xob tam sim no yuav tsub ncaj qha los ntawm resistor R1 nkaus xwb, raws li resistor R2 tau ua haujlwm luv los ntawm diode. Lub capacitor tso tawm raws li ib txwm los ntawm resistor, R2.

Ib qho ntxiv diode, D2 tuaj yeem txuas nrog ua ke nrog cov tshuaj tiv thaiv tawm, R2 yog tias xav tau los xyuas kom meej tias lub sijhawm them nqi hluav taws xob tsuas yog them dhau D1 thiab tsis dhau ntawm txoj kev sib tw ntawm R2.

Qhov no vim tias thaum lub sijhawm them nqi txheej txheem diode D2 txuas nrog hauv kev thim rov qab thaiv qhov ntws ntawm tam sim no los ntawm nws tus kheej. raws li: 0.693 (R1 x C).

Yog li lub luag haujlwm yuav tsum tau muab ua D = R1/(R1 + R2). Tom qab ntawd los tsim lub luag haujlwm lub voj voog tsawg dua 50%, tus tiv thaiv R1 xav tau tsawg dua tus tiv thaiv R2. Tab sis yav dhau los Circuit Court txhim kho lub luag haujlwm voj voog ntawm cov txheej txheem tso tawm los ntawm kev them lub sijhawm them nqi hluav taws xob, C1 los ntawm R1 + D1 ua ke thiab tom qab ntawd tso tawm nws dhau los ntawm D2 + R2 kev sib xyaw, qhov teeb meem nrog qhov kev teeb tsa Circuit Court no yog tias 555 oscillator Circuit siv cov khoom siv ntxiv, piv txwv li ob lub diodes.

· IC 4026 yog lub hauv paus kaum xyoo (10 Lub Xeev - suav 0 txog 9).

Tsis tas li nws muaj inbuilt 7 ntu qhia tsav tsheb uas ua rau cuam tshuam ntawm 7 ntu zaub yooj yim.

· 4026 tsav tsuas yog ib qho cathode xya ntu ntu qhia tawm. Raws li lub npe qhia txog ib qho cathode xya ntu ntu muaj nws cov cathode luv thiab hauv av.

· Tus Pin 1 yog Lub Sijhawm Teev Npe thiab Tus Pin 2 yog lub moos txwv uas yog siv rau kev xiam lub moos. Nws tuaj yeem siv los ncua kev suav thaum xav tau.

· Pin 15 (Tus tswv pib tus pin) pab kho lub txee. Pin 2 thiab 15 yog qhov ua haujlwm siab, yog li peb tau tsaws lawv kom pab tau suav cov txheej txheem. Lawv yuav tsum txuas nrog Vcc rau lawv qhov kev ua.

· Pin 3 yog tso saib tus pin uas ua rau pom.

· Tus lej 5 yog tus lej nqa tus pin uas tsim tawm nqa txhua lub sijhawm suav ntau dua 9. Nws tau siv rau txuas ntxiv qhov suav suav los ntawm kev txuas mus rau IC tom ntej tus pin tus lej.

· Koj tuaj yeem siv 555 astiv multivibrator zoo li lub moos nkag. Txhawm rau paub ntau ntxiv txog kev ua haujlwm yooj yim ntawm 555 timer astable nyeem Astable Multivibrator siv 555 timer.

· Rau 2 tus lej tso saib digital counter Circuit 0 rau 99 txuas qhov nqa tawm ntawm thawj IC raws li lub moos ntawm 2nd IC raws li pom hauv qab no. Koj tuaj yeem nce tus lej ntau npaum li koj xav tau los ntawm kev rov ua cov txheej txheem nrog ICs ntau dua thiab nthuav tawm.

· Resistor R1 yog siv tam sim no txwv resistor. Koj tuaj yeem hloov qhov ci ci ntawm cov zaub los ntawm kev sib txawv tus nqi tsis kam. Tab sis qhov ci ci no yuav tsis zoo ib yam rau txhua tus lej, Lub teeb ci zoo ib yam tuaj yeem ua tiav los ntawm kev sib txuas ib tus neeg tawm tsam rau txhua ntu anode.

· Hauv qhov no coj 7 ntu cov lus tso tawm Circuit Circuit peb tau siv tib lub txee digital IC (4026) ob qho tib si raws li txee thiab 7 ntu tsav tsheb. Ib qho cathode 7 ntu ntu tau siv ntawm no. IC siv ntawm no tsuas yog siv lub moos pulses rau kev ua haujlwm.
