Hauv txoj haujlwm no, peb yuav siv Arduino Uno los tswj lub vijtsam LCD los qhia lub sijhawm tam sim no thiab lub sijhawm uas lub tswb tau teeb tsa. Peb yuav siv cov nyees khawm los teeb tsa txhua lub sijhawm.

Cov ntaub ntawv:

• Arduino Uno -
• Breadboard -
• Jumper Wires (x13+) -
• 10 kohm resistors (x4) -
• LCD npo -
• 7 Khawm-https://vilros.com/collections/raspberry-pi-acces…
• Piezo Speaker -

Kauj ruam 1: Hookup Cov Lus Qhia

1. Txuas lub jumper hlau los ntawm 5V tus pin ntawm Arduino mus rau ib qho ntawm + cov ntsia ntawm lub khob cij.

Kauj ruam 2:

2. Txuas lub jumper xaim los ntawm GND tus pin ntawm Arduino mus rau - txoj kev tsheb nqaj hlau nyob ib sab ntawm + txoj kev tsheb nqaj hlau uas koj tau xaiv ntawm lub khob cij.

Kauj ruam 3:

3. Txuas lub vijtsam LCD mus rau lub zog, hauv av, thiab tus pin TX (tus pin 1).

Kauj ruam 4:

4. Muab 7 khawm tso rau ntawm lub khob cij nrog ob txhais ceg hla qhov sib txawv hauv lub khob cij.

Kauj ruam 5:

5. Tso 10 kohm resistors los ntawm txoj kab tsheb nqaj hlau nrog GND tus pin txuas rau nws mus rau hauv qab sab laug ntawm tus khawm.

Kauj Ruam 6:

6. Muab cov xov hluav taws xob tso rau nruab nrab ntawm tus hauv qab txoj cai tus pin ntawm cov nyees khawm thiab 5V txoj kev tsheb nqaj hlau ntawm koj lub khob cij.

Kauj ruam 7:

7. Muab cov xov hlau txuas ntawm tus pin 6, tom qab ntawd 8-13, thiab tus pin ntawm lub pob uas tus tiv thaiv tau txuas nrog.

Kauj ruam 8:

8. Tom ntej no, tso koj tus neeg hais lus Piezo ntawm lub khob cij thiab txuas tus pin 7 rau tus pin fais fab, tom qab ntawd 100 ohm resistor rau hauv av.

Kauj Ruam 9: Cov Lus Qhia Ua Haujlwm

1. Txheej txheem cej luam: Txoj haujlwm no yuav nug tus neeg siv teeb tsa lub sijhawm tam sim no ntawm lub zog pib ntawm cov zaub tam sim no thiab lub sijhawm lub tswb tau teeb tsa. Cov nyees khawm txuas nrog saum toj no yuav raug siv los teeb tsa txhua lub sijhawm. Los ntawm sab laug mus rau sab xis, lawv tau teev teev tam sim no, teev feeb tam sim no, teev AM tam sim no lossis yav tsaus ntuj, teeb tsa lub tswb teev, teev tswb tswb, teeb tsa tswb AM lossis PM. Khawm kawg yog siv los ntsiag to lub tswb thaum nws nrov nrov.

Kauj ruam 10:

2. Thawj qhov peb yuav tsum tau ua yog pib peb qhov sib txawv uas peb yuav siv.

// Initialize variables to useint teev = 0; // Teev rau lub sijhawm tam sim no feeb feeb = 0; //

Feeb rau lub sijhawm tam sim no int thib ob = 0; // Thib ob rau lub sijhawm tam sim no

int teev_a = 0; int // Teev rau lub sijhawm ceeb toom

feeb_a = 0; // feeb rau lub sijhawm ceeb toom

bool am_pm = tsis tseeb; // AM/PM toggle chij. Tsis tseeb yog AM, Tseeb yog PM

bool am_pm_a = tsis tseeb; // AM/PM toggle chij rau tswb. Tsis tseeb yog AM, Tseeb yog PM

int set_hr = 13; // Siv tus pin 13 teev teev

int set_min = 12; // Siv tus pin 12 los teev feeb int

set_am_pm = 11; // Siv tus pin 11 teev am/pm

int set_hr_a = 10; // Siv tus pin 10 teev teev rau tswb int set_min_a = 9; // Siv tus pin 9 los teev feeb rau tswb int set_am_pm_a = 8; // Siv tus pin 8 teev teev/teev tsaus ntuj rau lub tswb

tus neeg hais lus = 7; // Pin siv los hais lus ntsiag to = 6; // Pin kom nres tus hais lus

bool tswb = tsis tseeb; // Chij to toggle kom alarming

bool ntsiag to = tsis tseeb; // Chij qhia ntsiag to tsis tau nias

int cur_time = 0; // Hloov pauv rau lub sijhawm tam sim no

int ua = 0; // Hloov pauv rau lub sijhawm dhau los

3. Tom ntej no, peb yuav tsum teeb tsa lub vijtsam LCD thiab qhia rau tus neeg siv teeb tsa lub sijhawm tam sim no. Txij li qhov no tsuas yog xav tau ua tiav ib zaug, peb yuav ua nws hauv kev teeb tsa niaj hnub.

void teeb tsa () {

// Teeb tsa lub vijtsam LCD

Serial.begin (9600); // Initialize Serial ntawm 9600 baud

Serial.write (17); // Qhib lub teeb nraub qaum

Serial.write (24); // Qhib cov zaub rau, nrog tus cursor thiab tsis ntsais muag

Serial.write (12); // Tshem qhov screen

Serial.write (128); // Txav tus cursor mus rau kaum sab laug saum // teeb pinModes pinMode (set_hr, NTAWV); pinMode (set_min, INPUT);

pinMode (set_am_pm, INPUT);

pinMode (set_hr_a, INPUT);

pinMode (set_min_a, INPUT);

pinMode (set_am_pm_a, INPUT);

pinMode (tus hais lus, NTAWV);

pinMode (ntsiag to, INPUT);

// Thaum pib lub zog, kom cov neeg siv teeb tsa lub sijhawm tam sim no. Serial.print ("Teeb tsa lub sijhawm tam sim no"); ncua (2000);

Serial.write (12);

printTimes ();

cur_time = millis (); // Khaws lub sijhawm tam sim no}

Kauj ruam 12:

4. Tom qab ntawd, hauv lub voj kev niaj hnub, peb taug qab lub sijhawm thiab nyeem cov xwm txheej khawm kom pom tias tus neeg siv teeb tsa ib qho ntawm lub sijhawm.

void voj () {

// Khaws Sijhawm

keepTime ();

// Txheeb xyuas seb nws yog lub sijhawm tswb!

yog ((teev == teev_a && feeb == feeb_a &&! ntsiag to) || tswb) {suab nrov (hais lus, 2000, 500); // Tso lub suab 2000 Hz rau tus hais lus rau 500 ms

ncua (500); // Ncua 500 ms yog tias (! Tswb) {// Yog tias lub tswb raug kaw, qhib nws

}

}

// Yog tias tus neeg siv ntsiag to lub tswb los ntawm nias lub pob ntsiag to, tsis txhob ceeb yog tias (tswb &&! Ntsiag to && digitalRead (ntsiag to)) {

tswb = tsis tseeb;

ntsiag to = muaj tseeb; }

// Rov pib lub tswb yog (! Tswb && ntsiag to && feeb! = Feeb_a) {ntsiag to = tsis tseeb;

}

// Txheeb xyuas seb lub teeb pins mus siab, thiab yog li ntawd, nce tus nqi sib xws (digitalRead (set_hr) && teev <12) {

teev ++;

printTimes ();

debounce ();

}

lwm tus yog (digitalRead (set_hr) && teev == 12) {teev = 1;

yog (digitalRead (set_min) && feeb <59) {

feeb ++; printTimes ();

5. Ntawm no, koj yuav pom ob peb subroutines kuv tsim - debounce () thiab printTimes (). Debounce () yog siv los xyuas kom peb tsuas yog nyeem cov nyees khawm ib zaug. Txij li Arduino tshuaj xyuas ntau txhiab zaus hauv ib pliag, nws yuav xav tias lub pob raug nias ntau zaus thaum koj tsuas yog xav kom nws nyeem ib zaug. Debounce () yuav khov txoj haujlwm kom txog thaum lub pob tawm. printTimes () hloov kho lub vijtsam LCD, tab sis txij li qhov ntawd yog ob peb lo lus txib, Kuv ntaus lawv ib zaug thiab tom qab ntawd tuaj yeem hu rau subroutine txhua lub sijhawm lub sijhawm hloov pauv.

// Thaum ib qho ntawm cov nyees khawm raug nias, nyob hauv txoj haujlwm no tom qab ncua sijhawm 250 ms.

void debounce () {

thaum (digitalRead (set_hr) || digitalRead (set_min) ||

digitalRead (set_am_pm) || digitalRead (set_hr_a) ||

digitalRead (set_min_a) || digitalRead (set_am_pm_a)) {} ncua (250);

}

// Luam tawm cov sijhawm tshiab yog tias muaj kev hloov pauv

tsis muaj dab tsi printTimes () {

Serial.write (12);

Serial.print ("Lub Sijhawm Tam Sim No:");

yog (teev <10) {

}

Serial.print (feeb_a);

yog (am_pm_a) {

Serial.print ("PM");

}

lwm tus {

Serial.print ("AM");

}

}

// Ua kom lub sijhawm tsis muaj nuj nqis

keepTime () {

etime = millis () - cur_time;

yog (etime> = 1000 && thib ob <59) {

thib ob ++;

thib ob = 0; feeb =

0; teev ++; cov_time =

millis (); printTimes ();

}

lwm tus yog (etime> = 1000 && thib ob == 59 && feeb == 59 && teev == 12) {
