2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Txhawm rau daws cov teeb meem saum toj no, txoj haujlwm no thov tsim kho lub tsheb ntse uas tuaj yeem coj tib neeg mus rau qhov chaw lawv nres tsheb. Thiab kuv txoj kev npaj koom nrog GPS rau hauv lub tsheb tseem ceeb. Tsis tas yuav siv lub smartphone app txhawm rau taug qab lub tsheb, txhua qhov kev qhia yuav tsuas yog qhia ntawm tus yuam sij hauv lub tsheb.

Kauj Ruam 1: Daim Duab Sketch

Thaum tib neeg nias lub pob kom xauv lub tsheb, cov ntaub ntawv qhia chaw yuav raug kaw hauv lub microcontroller txiav. Tom qab ntawd, thaum tib neeg pib taug kev mus rau lub tsheb, qhov sib txawv LED tau teeb tsa kom ncaj qha mus rau txoj haujlwm ntawm lub tsheb thiab ntsais ntsais zaus qhia qhov deb ntawm lub tsheb. Lawv tuaj yeem yooj yim ua raws qhov ntsais ntsais LED thiab pom lub tsheb sai.

Kauj Ruam 2: Sau Cov Khoom Kho Vajtse

Cov no yog cov khoom siv hauv txoj haujlwm no. Qee qhov yog los ntawm cov khoom siv me me (cov ntawv ntim khoom, khawm, lub taub hau), lwm tus tau yuav los ntawm Adafruit lub vev xaib raug cai (Adafruit Feather M0, Adafruit Ultimate GPS module, Lpoly Battery and Coin Cell Battery) thiab Amazon (NeoPixel Ring - 12 RGB LED).

Kauj Ruam 3: Tsim Circuit Court

Neopixel_LED txuas nrog tus PIN 6 ntawm Feather M0

Button_Unlock txuas nrog tus PIN 12 ntawm Feather M0

Button_Lock txuas nrog tus PIN 13 ntawm Feather M0

Kauj Ruam 4: Kev Kho Vajtse Txuas

Muab cov taub hau tso nrog Adafruit M0 Feather, Adafruit Ultimate GPS Featherwing. Muab ob lub laug cam tso ua ke. GPS FeatherWing ntsaws ncaj rau hauv koj lub rooj plaub M0 yam tsis muaj xov hlau ntxiv.

GPS suav ua haujlwm

Xam lub Azimuth

// Suav Azimuth

ob azimuth (ob lat_a, ob lon_a, ob lat_b, ob lon_b) {

ob d = 0; lat_a = lat_a*PI/180; lon_a = lon_a*PI/180; lat_b = lat_b*PI/180; lon_b = lon_b*PI/180; d = sin (lat_a)*sin (lat_b)+cos (lat_a)*cos (lat_b)*cos (lon_b-lon_a); d = sqrt (1-d*d); d = cos (lat_b)*sin (lon_b-lon_a)/d; d = asin (d)*180/PI; rov d; }

Xam lub sijhawm ntawm lub moos LED, uas tseem yog kev qhia ntawm lub tsheb

// Xam lub sijhawm ntawm LED moos

int led_time (kaum ob lub kaum) {

tus chij = 0; yog (kaum sab xis = 15) {kaum_ sij hawm = kaum_ sij hawm + 1; } yog (chij == 1) {angle_time = 12 - angle_time; } rov qab angle_time; }

Xam qhov nrug ntawm tus neeg thiab nws lub tsheb

// Xam qhov deb

ob nrug (ob lat_a, ob lon_a, ob lat_b, ob lon_b) {

ob npaug EARTH_RADIUS = 6378137.0; ob npaug radLat1 = (lat_a * PI / 180.0); ob radLat2 = (lat_b * PI / 180.0); ob npaug a = radLat1 - radLat2; ob b = (lon_a - lon_b) * PI / 180.0; ob s = 2 * asin (sqrt (pow (sin (a / 2), 2) + cos (radLat1) * cos (radLat2) * pow (sin (b / 2), 2)))); s = s * EARTH_RADIUS / 10000000; rov s; }

LED Zaub Ua Haujlwm

Teeb LEDs hauv lub voj voog qhia tias nws pib taug kev

// LED ntiv nplhaib teeb pom kev ib ntawm ib qho qhia tias kev pib pib

void colorWipe (uint32_t c, uint8_t tos) {

rau (uint16_t kuv = 0; kuv strip.setPixelColor (i, c); strip.show (); ncua (tos);}}

Tau txais LED zaus raws qhov deb

// Tau Txais Zaus LED

int zaus (ob npaug nrug) {

int f = (int) nrug * 20; rov f; }

Tsau qhov tseeb ntawm LED qhia txog kev taw qhia ntawm lub tsheb

// Zaub ntawm LED

strip.clear ();

strip.show (); ncua (zaus (tsheb_ neeg_distance)); // ncua (500); strip.setPixelColor (angle_time, strip. Color (0, 0, 255)); strip.show (); ncua (zaus (tsheb_ neeg_distance)); // ncua (500);

// Disable LED

yog (button_flag == 1 && car_person_distance <5.0) {button_flag = 0; led_flag = 1; strip.clear (); strip.show (); }
