Kuv tau txais kuv txhais tes ntawm 74LS273 IC thaum kuv tau khaws qee yam khoom los ntawm lub qub satellite txais, qee yam kuv ua ntawm cov phiaj xwm thiab txuag nyiaj….

Qhov IC no nyob ntawm cov tswj vaj huam sib luag thiab tau txuas rau 4-Zauv 7-Segments LED zaub nrog qee qhov transistors. Qhov no ua rau kuv xav pom nws ua haujlwm li cas. Kuv yeej tsis tau siv ib qho ua ntej thiab yog li ntawd kuv tsis muaj lub tswv yim yuav ua li cas xaim nws thiaj li siv tau zoo.

Kuv tau tshawb nrhiav internet tsawg tab sis tsis pom ib daim duab thaiv kab mob lossis qauv piv txwv uas yuav pab kuv tawm. Muaj ntau cov ntaub ntawv khaws tseg thiab pinout npaj tau…. uas tau muaj txiaj ntsig thiab pib zoo rau kuv.

Kauj Ruam 1: Daim Ntawv Teev Npe:

Txhawm rau kom nkag siab zoo txog yuav ua li cas 74LS273 kev ua haujlwm, Kuv tau txiav txim siab los tsim ib qho yooj yim Circuit Court nrog pom kev nthuav tawm rau cov zis; ib qib ntawm cov lej ib txwm yog lub tswv yim zoo yog li kuv tau txiav txim siab ntawm 1-Zauv 7-Segmnet LED Zaub, thiab tsis txhob siv nws tus kheej, Kuv txiav txim siab siv lub txheej txheem me me los ntawm kev siv microcontroller (Arduino). Cov hauv qab no yog cov khoom siv xav tau:

Daim Ntawv Teev Npe:

• 74LS273 Octal D Flip-Flop IC
• Arduino NCO
• 1-Zauv 7-Segment LED Common Cathode Zaub
• 8x 200 Ohm Resistors (tus nqi nyob ntawm 7-Seg. LED Zaub)
• Cov qhob cij
• Kev sib txuas xov hlau
• 5 VDC Fais Fab Qhov Chaw

Kauj Ruam 2: 74LS273 Pinout:

Ua ntej tsim lub Circuit Court, cia peb muaj kev nkag siab txog cov txheej txheem uas kuv tab tom yuav muaj Arduino ua raws:

• Lub 74LS273 IC muaj 8 cov ntaub ntawv nkag pins thiab 8 latching Flip-Flop tso tawm pins, kuj nws muaj 2 inputs pins rau Clear thiab Clock.
• Txhawm rau tso saib tus lej koj tuaj yeem ua raws cov theem hauv qab no:

o Teeb tag nrho cov ntaub ntawv pins rau LOW

o Teeb tus pin kom LOW ces teeb nws mus rau HIGH

o Teeb tus pin cov ntaub ntawv xav tau rau HIGH; cov pins no sib raug rau tus lej koj xav tau los tso saib

o Teem Clock pin rau LOW ces teeb nws mus rau HIGH

Kauj Ruam 3: Nov Yog Qhov Khoos Phis Tawj Hock-up Diagram:

Nco tseg:

Kuv tau khiav mus rau qee qhov nyuaj vim li ntawd kuv tau sim 10K rub-down resistor ntawm Arduino tus pin-11 thiab 10K rub-up resistor ntawm Arduino tus pin-10, qhov no daws qhov teeb meem. Tab sis kuv tau tshem lawv tawm tom qab thaum kuv tau txais lub Circuit Court ua haujlwm tau zoo. Cov neeg tawm tsam tau pab kuv thaum sim, tab sis lawv tsis tsim nyog tom qab.

Txaus siab rau…. Vam tias qhov no muaj txiaj ntsig ….
