8. Muab tshuaj txhuam cov cai hauv qab no thiab nyem Upload nyob rau sab saum toj sab laug. (Tom qab ntawd, txhua qhov program rub tawm ua raws cov kauj ruam 5-8.)

9. Kev teeb tsa tiav thaum tag nrho 30 neoled pixels qhib.

#1. suav nrog header file thiab preprocessing

Ua ntej peb yuav tsum nqa lub tsev qiv ntawv Adafruit_NeoPixel uas tuaj yeem ua Neopixels.

Lub tsev qiv ntawv tuaj yeem siv los ntawm kev tshaj tawm cov khoom.

Adafruit_NeoPixel chav kawm tuaj yeem nkag 3 qhov ntsuas nyob hauv zej tsoom.

Thawj qhov ntsuas yog tus naj npawb ntawm LEDs.

qhov ntsuas ntsuas thib ob yog tus lej tus lej txuas nrog Neopixel cov lej nkag.

Qhov ntsuas thib peb yog kev xaiv cov tswv yim raws li cov yam ntxwv khoom. peb-xim WS2812b cov khoom siv 'NEO_GRB' cov tswv yim

#suav nrog

#define PIN 6 Adafruit_NeoPixel strip = Adafruit_Neopixel (30, PIN, NEO_GRB+NEO_KHZ800);

#2. teeb

Hauv qhov teeb tsa ib feem, pib qhov khoom thiab npaj nws rau kev siv.

'Adafruit_Neopixle_Object.begin ()' teeb tsa tag nrho cov LEDs kom tua.

'Adafruit_Neopixle_Object.show ()' tso tawm nrog qhov ci ci teeb tsa hauv LED.

void teeb tsa () {

strip.begin (); strip.show (); }

#3. lub voj loj

Qhov kev ua ntawm lub voj loj siv lub voj rau ua ntu zus (0.1 vib nas this) LEDs dawb

void voj () {

rau (uint16_t i = 0; kuv <strip.numPixels (); i ++) {strip.setPixelColor (i, 255, 255, 255); strip.show (); ncua (100); }}

Kauj Ruam 10: Sib dhos thiab Txuas rau Lub Log

2. Txuas Hall Sensor. (Xa mus rau Kauj Ruam 9)

3. Txuas tus ncej rau Arduino nruab nrab ntawm cov tsheb kauj vab. (Txuas cov ntaub ntawv Arduino mus rau lub thav duab tsheb kauj vab).

4. Ntxig rau Arduino txuas nrog Neopixel. (Ceev faj vim rab phom kua nplaum kub).

5. Ntxig rau qhov ntsuas nrog Hall sensor rau hauv Arduino, (Ruaj cov hlua khi kom lub Hall sensor tsis poob).

6. Cov laug los txuas roj teeb. (Ceev faj thaum koj muab tshuaj txhuam).

7. Kho nws nrog rab yaj phom. (Txuas tus qauv them nyiaj ntawm lub roj teeb kom ruaj ntseg chaw).

8. Txuas txhua kab ua ntej txuas rau Arduino, 9. Ntsaws raws li txhua tus lej tus lej. (Txuas cov kab dhia rau kev them nqi tsis tas yuav ua rau lawv tsis meej pem).

10. Ua kom tiav nrog rab yaj phom ib zaug, (Thov ceev faj tsis txhob poob).

Kauj Ruam 11: Txheeb INPUT (HALL Sensor Data)

*Txheeb xyuas software software kom pom tias lub ntsuas cua ua haujlwm li cas.

1. Muab tshuaj txhuam thiab xa cov cai hauv qab no.

2. Nyem rau Serial Monitor khawm nyob rau sab xis saum toj ntawm Arduino.

3. Thaum cov hlau nplaum nyob hauv kev sib cuag nrog Hall sensor ntau dua 1 thib ob, kev teeb tsa tiav thaum lo lus "tiv tauj sib nqus" tshwm ntawm daim ntawv saib.

----------------------------------------------------------------------- ----------------------------------------------------------------------- ----------------------------------------------------------------------- #1. Txhais tus lej tus lej thiab teeb tsa

Thawj qhov teeb tsa tus lej tus lej siv Hall sensor thiab teeb tus lej tus lej ua qhov Chaw Nkag Nkag nkaus xwb.

Teem kev sib txuas lus txhawm rau txheeb xyuas cov ntaub ntawv ntawm Hall sensor ntawm tus saib xyuas.

#define HALL 2

teeb tsa tsis muaj dab tsi () {pinMode (HALL, INPUT); Serial.begin (9600); }

#2. lub voj loj

Txheeb xyuas Hall cov ntaub ntawv ntawm 0.1 vib nas this ib ntus.

Yog tias cov hlau nplaum tau hnov thiab hloov pauv cov ntaub ntawv, "kev sib cuag sib nqus" tau tso tawm rau lub ntsuas saib.

void voj () {

yog (digitalRead (HALL)) {Serial.println ("tiv tauj sib nqus"); } ncua (100); }

Kauj Ruam 12: Coding Algorithm

*Tsim cov laj thawj thiab cov lej los tswj Neopixels raws li qhov ntsuas qhov ntsuas.

1. Muab tshuaj txhuam thiab xa cov cai hauv qab no.

2. Nws yog ib txwm rau cov duab tsis raug tso tawm kom raug vim tias tsis muaj cov thav duab tsim. Tab sis koj tuaj yeem pom nws ua haujlwm ntxhib.

3. Ceev nrooj kov thiab tso lub Hall sensor thiab cov hlau nplaum hauv 1 thib ob. Rov ua qhov haujlwm no txog 10 zaug.

4. Kev teeb tsa tiav thaum cov xim ntawm Neopixels hloov tsis tu ncua.

#1. Xws li cov ntawv header thiab kev npaj ua ntej

Ua ntej, peb yuav tsum nkag siab tias Arduino Mega lub cim xeeb tsis loj txaus los tuav cov duab.

Yog li ntawd, 'avr/pgmspace' header file tau siv los siv qhov chaw nco sib txawv.

Txhawm rau siv Neopixels, koj tshaj tawm cov khoom thiab teeb tsa tus lej I/O tus lej.

Cov duab duab loj dhau rau kev sau npe, yog li rub tawm thiab muab cov ntawv txuas nrog.

#suav nrog

#include #define PIN 6 #define NUMPIXELS 30 #define HALL 2 Adafruit_NeoPixel strip = Adafruit_NeoPixel (NUMPIXELS, PIN, NEO_RGB + NEO_KHZ800); // paste array hauv 'image_array_1.txt' // "'image_array_2.txt' //" 'image_array_3.txt' // "'image_array_4.txt'

#2. Kev hloov pauv thoob ntiaj teb & teeb tsa

Teeb lub ntiaj teb sib txawv.

Qhov tseem ceeb yog teeb tsa qhov ci ci, nws tau txiav txim siab lub neej-voj voog ntawm cov khoom.

int suav = 0;

ob v = 0; ob lub xeem_v = 0; ob npaug timer = micros (); ob npaug ex_timer = micros (); ob npaug kawg_timer = micros (); int cov = 36; txp = 35; rgb ib = 3; ob q_arr [2] = {0, 0}; int HALL_COUNT = 0; ob VELO; ua ob zaug_timer = micros (); teeb tsa tsis muaj dab tsi () {strip.setBrightness (255); strip.begin (); strip.show (); Serial.begin (230400); }

#3. lub voj loj - duab qhia tawm ib feem

Txoj cai no yog nqe lus hais txog yuav ua li cas tso tawm lub sijhawm lub log tig los ntawm kev daws teeb meem.

Qhov no siv lub voj voog tig lub log tsheb kauj vab ib zaug uas yog qhov ntsuas tseem ceeb heev.

Tsis tas li, nws yog ib qho tseem ceeb kom nyeem cov duab cov ntaub ntawv los ntawm kev nco.

void voj () {

yog ((suav (ex_timer / 120.0) - (micros () - processing_timer)))) {timer = micros (); yog (VELO> 360000) {rau (int i = 0+5; i <pix; i ++) {strip.setPixelColor (i - 5, strip. Color (pgm_read_byte (& (image_1 [suav] [1]))), pgm_read_byte (& (image_1 [suav] [2])), pgm_read_byte (& (image_1 [suav] [0]))))) } strip.show (); } lwm yog (VELO 264000) {rau (int i = 0+5; kuv <pix; i ++) {strip.setPixelColor (i - 5, strip. Color (pgm_read_byte (& (image_2 [suav] [1]), pgm_read_byte (& (image_2 [suav] [2])), pgm_read_byte (& (image_2 [suav] [0]))))) } strip.show (); } lwm tus yog (VELO 204000) {rau (int i = 0+5; i <pix; i ++) {strip.setPixelColor (i - 5, strip. Color (pgm_read_byte (& (image_3 [suav] [1]), pgm_read_byte (& (image_3 [suav] [2])), pgm_read_byte (& (image_3 [suav] [0]))))) } strip.show (); } lwm yog (VELO <= 204000) {rau (int i = 0 + 5; i = 120)) {rau (int i = 0 + 5; i <pix; i ++) {strip.setPixelColor (i - 5, strip. Color (0, 0, 0)); } strip.show (); }

#4. lub ntsiab lus tseem ceeb - ua thiab ntsuas lub sijhawm ntsuas & ntsuas

Qhov no yog qhov tseem ceeb tshaj plaws ntawm tag nrho cov kab ke.

Ua ntej, txheeb xyuas lub sijhawm coj los ua kom tiav tag nrho cov cai thiab hloov kho LED lub sijhawm tso tawm ib lub hlis.

Lub sijhawm hnov txhua lub sijhawm uas lub log tig los kwv yees lub sijhawm ntawm lub voj voog tom ntej.

Kev nrawm tuaj yeem kwv yees tau los ntawm kev rho tawm lub sijhawm ntsuas ntsuas kawg ntawm lub sijhawm ntsuas lub sijhawm.

Lub kaw lus suav lub sijhawm ua haujlwm thiab ua kom nrawm los laij ntev npaum li cas cov LEDs tig mus tas li.

processing_timer = micros ();

yog ((digitalRead (HALL) == HIGH) && (HALL_COUNT == 1)) {VELO = v; v = micros () - last_timer; ex_timer = q_arr [0] - q_arr [1] + v; last_timer = micros (); q_arr [0] = q_arr [1]; q_arr [1] = v; suav = 0; HALL_COUNT = 0; } lwm tus yog (digitalRead (HALL) == LOW) {HALL_COUNT = 1; }}

Kauj Ruam 13: Siv Software
