Yuav Ua Li Cas Digital Stopwatch Siv 555: 3 Cov Kauj Ruam

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Kuv tau ua lub moos nres yooj yim siv 3 xya ntu ntu LED zaub uas

thawj zaug koj rau tso tawm ntu 10 ntawm vib nas this lwm qhov thib ob thiab thib peb rau ntau ntawm 10 lub tsev so vib nas this.

Kuv siv 555 timers hauv hom astable uas muab teeb liab rau 1 thib ob rau IC 4033.

IC 4033 yog johnson decoder ic thiab BCD IC. Raws li lub teeb liab los ntawm 555 timer IC 4033 hloov mus rau hauv binary code thiab xa mus rau 7 ntu tso saib.

Lub sijhawm nrawm tuaj yeem hloov kho los ntawm kev hloov ua ntej lub moos los yog lub moos xauv.

Circuit ua haujlwm ntawm 8-12V.

Raws li kuv tsis muaj cov duab ntawm Circuit thaum kuv tab tom ua tab sis kuv ua video, thov saib qhov no.

Kauj Ruam 1: Sau cov Cheeb Tsam Xav Tau

Txhua tus neeg tiv thaiv yog 1/2 W

R1 -R21 -150 hli

R22-100 hli

R23- 10k ohm

R24-47k hmo

R25- 100k ohm preset

R26 & R27 -10k ohm

CAPACITOR C1-1uf, 25v (hluav taws xob)

LED ntsuab xim

2 × NE555 nrog 8 tus pin IC puag

3 × CD4033 IC nrog 16 tus pin IC puag

3 × Common cathode 7 ntu ntu

3 × thawb nyees khawm

Kauj Ruam 2: Muab Cov Khoom Siv

Saum toj no kuv muab daim duab qhia chaw.

Muab txhua yam khoom siv raws li qhov ntawd thiab tso IC puag tsis yog IC li thaum siv lub ntsuas kub tuaj yeem ua rau koj lub IC sab hauv puas.

thiab muaj ob qhov txuas rau tus lej thib 6 ntawm IC 4033, qhov ntawd tsis yog lawm.

tus pin 6 ntawm IC yuav tsum mus rau xya ntu thiab lwm tus lej thib 6 qhia hauv daim duab qhia chaw yog tus lej tiag 8, yog li ceev faj thaum siv lub tshuab.

Kauj Ruam 3: Kev hloov kho ntawm Stopwatch

kho qhov ua ntej, nce lossis txo qhov nrawm ntawm lub sijhawm ua thaum teeb tsa lub moos nres, ua lub sijhawm nrog koj lub xov tooj ntawm tes timer.

Stopwatch tseem tuaj yeem qhia hauv 50 feem ib ntawm ob los ntawm kev kho ua ntej.

Yog tias koj xav tau cov lus piav qhia ntxaws saib kuv cov vis dis aus kuv muab hauv qab no
