Lub teeb no tuaj yeem hloov kho tau yog li nws muaj kev koom tes thiab lom zem rau cov menyuam. Nws yog lub teeb duab ntxoov ntxoo hloov pauv uas tsim cov xim sib txawv thiab tsim qauv ntawm phab ntsa. Yog li ntawd, qhov no tau txais txiaj ntsig zoo rau cov neeg uas tab tom nrhiav kom pom ntau dua thiab ntau lub teeb duab ntxoov ntxoo tuaj yeem kho tau rau ntau lub hnub nyoog.

Peb kev tshoov siab rau lub teeb duab ntxoov ntxoo no yog los ntawm:

Kauj Ruam 1: Cov Khoom Koj Yuav Tsum Tau

1 Arduino UNO

1 USB kab

1 RGB LED

1 Daim ntawv me me

4 Jumper xov hlau

1 Square iav los yog lub raj mis

4 Cov ntawv ntawm cov ntawv taug qab

4 Cov ntawv ntawm kev tsim ntawv

1 Kub kua nplaum phom

Kauj Ruam 2: Txuas Txuas RGB LED

Siv RGB LED thiab khoov qhov tsis zoo. Tom qab ntawd tso qhov tsis zoo nyob rau hauv kab tsis zoo xiav uas nyob ntawm sab saum toj ntawm lub khob cij. Tom qab, koj yuav tsum khoov peb lwm ceg ntawm RGB LED thiab tso lawv mus rau hauv nruab nrab ntawm lub khob cij hauv kab sib txawv. Peb muab lub jumper xiav tso rau hauv kab A, kab 37. Cov hlua hlau dub tau muab tso rau hauv kab A, kab 41 ntawm lub khob cij. Cov xaim hluav taws xob xaim xaim xaim tau muab tso rau hauv kab A, kab 43. Lwm qhov xaim xaim xaim hluav taws xob nyob hauv kab H, kab 39. Nws yog qhov tseem ceeb heev uas koj tso peb txoj kab nqes rau hauv kab sib txawv hauv lub khob cij. Qhov tsis zoo nyob ntawm kab J, kab 39. Kab 39 yog kab nkaus xwb uas txuas rau kab hlau dawb thib ob. Tsis muaj tus tiv thaiv tso rau hauv kab ntawd. Hauv kab J peb tau tso ib qho prong los ntawm LED rau hauv kab sib xws nrog txhua lub jumper xaim. Lub kawg, tso (330 ohms) resistors qhov twg lawv tau txuas rau ib qho ntawm RGB LED prongs thiab lwm yam peb lub xov hlau txuas. Peb tso thawj resistor hauv kab 37, kab D thiab F. Tus tiv thaiv thib ob yog kab 41, kab D thiab F. Peb tus tiv thaiv kab thib peb tau muab tso rau hauv kab 33 kab D thiab F. Peb tso cov resistors rau hauv lub khob cij kom nws tsis txhob hlawv tawm ntawm RGB LED.

Kauj Ruam 3: Txuas Arduino UNO

Kev thaiv koj li Arduino UNO nyob ntawm kab uas koj tau xaiv hauv koj tus lej. Koj yuav tsum tau siv daim ntawv qhia ntawv txhawm rau txuas cov neeg tawm tsam uas txuas nrog LED mus rau Aurduino UNO.

Hauv kab lus tawm tswv yim peb tso lub xaim hluav taws xob thib ob txuas rau hauv 3.3 volts. Hauv kab ntawv tso tawm, xaim xaim xaim tau nkag hauv kab 9. Cov xaim xaim xaim dub tau nkag rau hauv 6. Thawj lub xaim xaim xaim xaim tau nkag rau kab 5.

Kauj ruam 4: Software

1. Peb siv Aurduino Tsim software uas muaj online los ntaus peb cov cai.

2. Nov yog cov cai peb siv:

// txhua tus pin sib raug rau cov xim LED: int led0 = 10; // int = integer led0 = 10 (xim)

int led1 = 11;

int led2 = 12;

// Tshaj tawm cov kev hloov pauv sab hauv

int qhov ci = 200;

int liab = 0;

int xiav = 0;

ntsuab ntsuab = 0;

// qhov kev ua haujlwm no khiav txhua lub sijhawm koj ntaus khawm rov pib dua

void teeb tsa () {

pinMode (coj 0, OUTPUT); pinMode (coj 1, OUTPUT); pinMode (coj 2, OUTPUT); }

// qhov kev ua niaj hnub no txuas mus tas li

void voj () {

rau (ntab x = 0; x <PI; x = x + 0.000004) {

liab = ci ntsa iab * abs (sin (x * (180/PI))); // laij cov duab ci ci

ntsuab = ci ntsa iab * abs (sin ((x+PI/3) * (180/PI)))); // suav cov zaub ci ci

xiav = ci ntsa iab*abs (sin ((x+(2*PI)/3)*(180/PI)))); // xam blues ci ntsa iab

analogWrite (coj 0, liab); // xa tus nqi mus rau LED analogWrite (led1, geen); // xa tus nqi mus rau LED analogWrite (led2, xiav); // xa tus nqi mus rau LED}}

3. Tom qab ntawd peb tau txuas peb lub xov tooj USB txuas rau lub khoos phis tawj thiab txuas rau lwm qhov kawg rau Arduino UNO yog li ntawd peb tuaj yeem tso cov cai. Ntawm lub vev xaib nyem upload thiab cov cai yuav tso rau hauv koj li Arduino UNO.

Kauj Ruam 5: Txhim Kho Cov Qauv

Khoom siv:

• Popsicle sticks
• Kub kua nplaum phom
• Ntawv tsim
• Luam ntawv

Kauj Ruam 6: Tsim

Cov qauv tsim peb siv rau peb cov duab ntxoov ntxoo hmo ntuj rau txhua ntawm plaub sab.

Tus tsim peb siv:
