Nyob zoo txhua tus, Kuv nyiam ua haujlwm nrog LED qhia nrog 7 ntu lossis nrog dot matrix thiab kuv twb tau ua ntau txoj haujlwm sib txawv nrog lawv.

Txhua lub sijhawm lawv nthuav vim tias muaj qee yam kev ua khawv koob zoo li cas lawv tuaj yeem ua haujlwm vim tias yam koj pom nws yog qhov tsis pom kev zoo!

Cov lus qhia muaj ntau tus pin rau kev sib txuas nrog Arduino (lossis lwm lub microcontroller) thiab cov kev daws teeb meem zoo tshaj plaws yog siv cov thev naus laus zis ntawm cov ntaub ntawv sib tshooj kom txo qis kev siv lawv cov chaw nres nkoj.

Thaum koj ua qhov no, txhua ntu lossis ib qho LED yuav qhib rau ob peb qhov kev tshwm sim (miliseconds lossis tsawg dua), tab sis qhov rov ua dua ntawm qhov ntawd ntau zaus hauv ib pliag tsim qhov tsis pom ntawm cov duab uas koj xav pom.

Rau kuv qhov ntxim nyiam tshaj plaws yog txhim kho cov laj thawj, txoj haujlwm kom paub seb lawv tuaj yeem qhia cov ntaub ntawv raug raws li koj li haujlwm.

Hauv ib qhov haujlwm uas siv cov lus xav tau ntau lub sijhawm los sib sau ua ke txhua yam ntawm lub khob cij nrog ntau lub xov hlau rau kev sib txuas.

Kuv paub muaj ntau qhov sib txawv ntawm kev ua lag luam khiav nrog I2C, nrog txoj hauv kev yooj yim (lossis tsis yog), txhawm rau ua haujlwm rau lawv thiab kuv tau siv lawv ib yam nkaus tab sis kuv nyiam ua haujlwm nrog cov khoom txheem xws li 74HC595 (multiplexer IC) thiab ULN2803 (tsav tsheb) vim tias lawv muab kev tswj hwm koj ntau ntxiv hauv koj qhov haujlwm thiab tseem muaj zog thiab ntseeg tau hauv koj kev siv.

Txhawm rau ua kom yooj yim cov txheej txheem sib dhos Kuv tau tsim LED Dipslay Module rau ntau lub hom phiaj siv cov khoom yooj yim thiab ib txwm muaj hauv Arduino lub ntiaj teb.

Nrog tus qauv no koj tuaj yeem ua haujlwm nrog dot matrix nrog ob xim LEDs hauv ob tus qauv loj (loj dua thiab me dua) thiab tseem koj tuaj yeem tswj 7 Seg x 4 Tus lej tso saib uas muaj ntau heev thiab yooj yim mus nrhiav tau hauv khw.

Thiab koj kuj tseem tuaj yeem ua haujlwm nrog cov qauv no hauv cascade ntawm txoj hauv kev (cov ntaub ntawv sib txawv rau hauv cov lus qhia) lossis ntawm txoj kev paralell (tib cov ntaub ntawv rau hauv cov lus).

Yog li cia saib seb qhov qauv no tuaj yeem ua haujlwm li cas thiab pab koj hauv koj qhov kev txhim kho!

Kauj ruam 4: Programming

Txog rau kev ua haujlwm koj yuav tsum nco ntsoov qee cov ntsiab lus tseem ceeb txog kev tsim kho vajtse thiab hais txog kev hloov pauv npe 74HC595.

Lub luag haujlwm tseem ceeb ntawm 74HC595 yog hloov 8-Bit Serial-In rau hauv 8 Parallel-Out Shift.

Txhua cov ntaub ntawv hauv xov tooj mus rau Tus Pin #14 thiab ntawm txhua lub moos teeb liab cov khoom mus rau nws qhov sib thooj-tawm tus pin (Qa rau Qh).

Yog tias koj txuas ntxiv xa cov ntaub ntawv ntau ntxiv, cov khoom yuav raug tshem tawm ib tus mus rau Pin #9 (Qh ') raws li cov ntawv tso tawm ib zaug ntxiv thiab vim yog qhov ua haujlwm no koj tuaj yeem tso lwm daim txuas rau hauv cascade.

Tseem ceeb:

Hauv txoj haujlwm no peb muaj peb ICs ntawm 74HC595. Thawj ob txoj haujlwm los tswj kab (nrog POSITIVE logic) thiab qhov kawg los tswj kab (nrog NEGATIVE logic vim PNP transistors ua haujlwm).

Lub tswv yim zoo txhais tau tias koj yuav tsum xa lub HIGH qib teeb liab (+5V) los ntawm Arduino thiab Cov laj thawj tsis zoo txhais tau tias koj yuav tsum xa lub teeb liab theem qis (0V).

Dot matrix ntawm LEDs

1. Thawj yog rau cov txiaj ntsig ntawm cathodes ntawm LED liab (8 x) >> COLUMN RED (1 txog 8).
2. Qhov thib ob yog rau kev tso tawm L ntawm cathodes ntawm Green LEDs (8 x) >> COLUMN GREEN (1 txog 8).
3. Qhov kawg yog rau qhov tso tawm ntawm anodes ntawm txhua lub LEDs (08 x Liab & Ntsuab) >> LINES (1 txog 8).

Piv txwv li, yog tias koj xav tig tsuas yog Green LED ntawm kab 1 thiab kab 1 koj yuav tsum xa cov lej hauv qab no raws li cov hauv qab no:

1º) LIS

~ 10000000 (tsuas yog thawj kab tau teeb tsa) - Lub cim ~ yog rov thim tag nrho cov khoom los ntawm 1 txog 0 thiab hloov pauv.

2º) COLUMN Ntsuab

10000000 (tsuas yog thawj kab ntawm Green LED tau teeb tsa)

3º) COLUMN RED

00000000 (txhua kab ntawm Liab LEDs tawm)

Arduino nqe lus:

shiftOut (dataPin, clockPin, LSBFIRST, ~ B10000000); // Tsis zoo logic rau kab

shiftOut (dataPin, clockPin, LSBFIRST, B10000000); // Cov laj thawj zoo rau kab ntsuab

shiftOut (dataPin, clockPin, LSBFIRST, B00000000); // Cov laj thawj zoo rau kab liab

Lus Cim:

Koj tseem tuaj yeem ua ke ob qho tib si LEDs (Ntsuab & Liab) los tsim cov xim YELLOW raws li hauv qab no:

shiftOut (dataPin, clockPin, LSBFIRST, ~ B10000000);

shiftOut (dataPin, clockPin, LSBFIRST, B10000000);

shiftOut (dataPin, clockPin, LSBFIRST, B10000000);

7 Tshooj zaub

Rau cov hom kev qhia no ua ntu zus yog tib yam. Qhov txawv tsuas yog tias koj tsis tas yuav siv Green LEDs.

1º) DIGIT (1 txog 4 ntawm sab laug mus rau sab xis) ~ 10000000 (teeb tus lej #1)

~ 01000000 (teeb tus lej #2)

~ 00100000 (teeb tus lej #3)

~ 00010000 (teeb tus lej #4)

2º) Tsis siv

00000000 (txhua qhov teeb tsa rau xoom)

3º) SEGMENTS (A rau F thiab DP - txheeb xyuas koj cov ntawv teev tseg)

10000000 (teev ntu A)

01000000 (teev ntu B)

00100000 (teeb ntu C)

00010000 (teev ntu D)

00001000 (teeb ntu E)

00000100 (teev ntu F)

00000010 (teeb ntu G)

00000001 (teeb DP)

Arduino piv txwv los teeb Zaub #2 nrog tus lej 3:

shiftOut (dataPin, clockPin, LSBFIRST, ~ B01000000); // Teeb DISPLAY 2 (Tsis zoo logic)

shiftOut (dataPin, clockPin, LSBFIRST, 0); // Teeb cov ntaub ntawv rau xoom (tsis siv)

shiftOut (dataPin, clockPin, LSBFIRST, B11110010); // Teeb ntu A, B, C, D, G)

Thaum kawg, thov ua cov txheej txheem no koj tuaj yeem tswj hwm ib qho LED ntawm koj cov zaub thiab tseem koj tuaj yeem tsim cov cim tshwj xeeb uas koj xav tau.
