Kuv tau ua daim duab roulette. Yog tias koj nias lub pob, tus roulette pib tig. Yog tias koj nias dua, tus roulette nres tig thiab nrov nrov!

Kauj ruam 1: Circuit Court

Peb siv tsuas yog tus hais lus txuas thiab khawm.

Tus lej xov tooj ntawm tus xov tooj tau sau rau ntawm qhov program.

khawm = obniz.wired ("Button", {signal: 6, gnd: 7}); speaker = obniz.wired ("Speaker", {signal: 0, gnd: 1});

Kauj Ruam 2: Hloov Daim Duab Rulette

Hauv HTML, koj tuaj yeem siv "CSS hloov pauv". Piv txwv li, qhov no yog cov cai ntawm cov duab tig 90 degree.

document.getElementById ("roulette"). style = "hloov pauv: tig (90deg);";

Txhawm rau pib thiab nres tig qeeb, ntxiv qhov hloov pauv ceev rau kev hloov qib ntawm ib tus ncej.

cia ceev = 0; tso deg = 0; muaj nuj nqi tig () {deg += ceev; document.getElementById ("roulette"). style = "hloov pauv: tig ("+deg+"deg);"

}

setInterval (tig, 10);

Kauj ruam 3: Pib

Koj puas xav beep ntawm roulette tsis hloov? Nrog rau qhov no, koj tuaj yeem beep ntawm 440Hz 10ms.

hais lus.play (440); tos obniz.wait (10); hais lus.stop ();

Nov yog yuav ua li cas thiaj paub txog kev hloov pauv ntawm roulette no.

yog (Math.floor ((deg + ceev) / (360 / 7.0)) - Math.floor (deg / (360 / 7.0))> = 1) {onRouletteChange (); }

Yog li, qhov no yog txoj cai ntawm tig thiab beep.

cia ceev = 0; tso deg = 0; muaj nuj nqi tig () {// ntawm qhov hloov pauv tus nqi yog (Math.floor ((deg + nrawm) /(360 /7.0)) - Math.floor (deg /(360 /7.0))> = 1) {onRouletteChange (); } deg += ceev; document.getElementById ("roulette"). style = "hloov pauv: tig ("+deg+"deg);"

}

setInterval (tig, 10);

async muaj nuj nqi onRouletteChange () {

yog (! hais lus) {rov qab;} hais lus.play (440); tos obniz.wait (10); hais lus.stop (); }

Kauj ruam 4: Pib ntawm Khawm Thawb

Txhawm rau paub khawm lub xeev, ntxiv cov khawm khawm Lub Xeev thiab teeb tus nqi ntawm lub xeev khawm tam sim no.

button.onchange = muaj nuj nqi (nias) {buttonState = nias; };

Thiab tseem ntxiv var theem rau lub xeev tam sim no ntawm roulette.phase tau teeb tsa ib qho ntawm no.

const PHASE_WAIT_FOR_START = 0; const PHASE_ROTATE = 1; const PHASE_STOPPING = 2; const PHASE_STOPPED = 3;

Piv txwv li, thaum theem PHASE_WAIT_FOR_START thiab koj xav mus rau theem tom ntej.

yog (theem == PHASE_WAIT_FOR_START) {ceev = 0; yog (buttonState) {theem = PHASE_ROTATE; }}

Txhawm rau ua kom cov txheej txheem nrawm dua, hloov pauv nrawm.

yog (theem == PHASE_ROTATE) {nrawm = nrawm+0.5; }

Txhawm rau txo txoj cai, hloov pauv nrawm.

:

yog (theem == PHASE_STOPPING) {nrawm = nrawm-0.2; }

Cov no yog ib feem ntawm roulette. Cia peb ua!
