Video: 556 Lub Sijhawm Muab Lub Sijhawm Teev Taw rau 2 Xyoo Xeem Uas Yuav Tsav 20 LEDS: 6 Kauj Ruam
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25
Cov Lus Qhia no yuav qhia yuav ua li cas 556 tus timer yuav muab lub moos nkag mus rau 2 lub xyoo caum suav. Qhov kaum xyoo suav yuav tsav 20 LEDS. Cov LEDs yuav ntsais ntsais ntawm 10.
Kauj ruam 1: 556 Timer
nws 556 timer yog ob qho hloov pauv ntawm 555 timer. (saib duab)
Hauv lwm lo lus, muaj ob 555 lub sijhawm ua haujlwm sib cais. Ob lub sijhawm ua haujlwm ywj siab ntawm ib leeg. Lawv siv tib lub zog qhov hluav taws xob thiab hauv av Txhua Lub Sijhawm tau muab nrog nws tus kheej qhov pib, ua rau, tso tawm, tswj, rov pib dua thiab tso cov pins. 556 tuaj yeem muab cov tswv yim moos rau lub xyoo caum txee
Kauj Ruam 2: Decade Counter
Lub xyoo caum txee yog lub nti ntev hu ua 74HC4017 Nws yog nyob hauv thawj daim duab. Qhov IC tso tawm yog nyob hauv daim duab thib ob.
Lub Kaum Ib Hlis cov suav yog qhov sib txawv tshwj xeeb. Feem ntau cov suav digital yog binary. Lawv suav hauv 2 lub hauv paus ntawm 0 lossis 1. Decade counter ua tau ib yam, tab sis suav txog 10 hauv ib ntu. Cov txiaj ntsig yog Q 0-Q9. Cov txiaj ntsig no yuav txuas nrog cov neeg tawm tsam (440) thiab LEDS, Cov LEDS yuav sau npe cov txiaj ntsig thiab teeb tawm (LEDS) ua ntu ntu ntawm sab laug mus rau sab xis. Koj tuaj yeem suav daim ntawv 1 txog 10 los ntawm kev saib lub LEDS teeb nyob rau hauv ib ntu.
Kauj Ruam 3: Qhov Chaw

2 -25k; potientometers
Arduino uno thiab xov hlau (tib yam li saum toj no)
Kauj Ruam 4: Xaus
Cov Lus Qhia no qhia koj li cas koj tuaj yeem siv 556 tus timer los muab lub moos nkag mus rau 2 Xyoo Xyoo. Lub xyoo caum yuav suav thiab 10 LEDS yuav ntsais muag. Qhov ntsuas qhov ntsuas hauv 556 Circuit yuav tswj tus nqi uas LEDS ntsais.
Qhov no yog kev lom zem Circuit Court ua. Kuv ua nws ntawm Tinkercad.
Qhov txuas yog;
www.tinkercad.com/things/kX2QxAEkN5L-swank…. Koj yuav xav tau tus as khauj ntawm Tinkercad kom pom nws.
Kuv nyiam ua qhov Circuit no. Nws tuaj yeem siv rau kev lom zem.
Ua tsaug!
