74HC595 thiab LEDs
74HC595 yog Serial rau Parallel Converter uas muaj yim qhov tso tawm (zoo meej) thiab peb cov khoom siv uas koj siv los pub cov ntaub ntawv rau hauv nws me ntsis ntawm ib lub sijhawm.
Cov nti no ua rau nws qeeb me ntsis rau kev tsav cov LEDs (koj tuaj yeem hloov cov LEDs li 500,000 zaug ib pliag es tsis yog 8,000,000 ib ob) tab sis nws tseem ceev heev, txoj kev sai dua li tib neeg tuaj yeem ntes tau, yog li nws tsim nyog. 74HC595 hloov npe
yog hom nti uas tuav tau dab tsi tuaj yeem xav txog yog yim qhov chaw memo ry, txhua qhov tuaj yeem yog 1 lossis 0. Txhawm rau teeb tsa txhua qhov txiaj ntsig ntawm lossis tawm, peb pub rau hauv cov ntaub ntawv siv 'Data' thiab 'Clock' pins ntawm lub nti.
4 tus lej 7 ntu zaub
7 segment qhia muaj 7 LEDs, hu ua ntu, teem rau hauv cov duab ntawm "8". Feem ntau ntawm 7- ntu qhia tau tiag tiag muaj 8 ntu, nrog rau lub cim ntawm sab xis ntawm tus lej uas ua tus lej lej.
Thaum siv 4-digit 7-segment zaub, cov anode feem ntau lossis cathode tus pin siv los tswj tus lej twg tshwm sim. Txawm hais tias tsuas muaj ib tus lej ua haujlwm, lub hauv paus ntsiab lus ntawm Persistence of Vision ua rau koj pom txhua tus lej tshwm sim vim tias txhua qhov scanning ceev nrawm heev uas koj tsis tshua pom cov ntu.
Los ntawm kev tsim lub voj voog, cov neeg siv tuaj yeem ua cov duab yooj yim uas qhia qee tus lej, lossis ntau qhov nyuaj, suav-up timer lossis hluav taws xob dov tsuav.
Stepper Tsav
Stepper motors yog DC motors uas txav hauv cov kauj ruam tsis sib xws. Lawv muaj ntau lub coils uas tau teeb tsa hauv pawg hu ua "theem". Los ntawm energizing txhua theem nyob rau hauv ib ntus, lub cev muaj zog yuav tig, ib kauj ruam ntawm ib lub sij hawm. Nrog lub computer tswj stepping koj
tuaj yeem ua tiav qhov tseeb heev thiab / lossis tswj ceev. Vim li no, stepper motors yog lub cev muaj zog ntawm kev xaiv rau ntau qhov kev tswj xyuas qhov tseeb. txoj kev yooj yim tshaj plaws
ntawm interfacing ib tug unipolar stepper lub cev muaj zog rau tshaj Arduino yog siv ib tug breakout
rau ULN2003A transistor array nti, Siv qhov hluav taws xob rau txhua qhov coils hauv ib ntu tshwj xeeb.
