nyob zoo cov neeg! lub sijhawm no kuv xav qhia qhov tshwm sim ntawm kuv qhov project, piv txwv li coj kev siv zog. coj kev siv yog ib qho xwm txheej uas qhov kev siv ntawm LED hloov pauv txhua 200 milliseconds. ua tus nqi ntawm LEDs sib txawv kom cov LEDs zoo li cov khoom hlawv. Tsis tau tos ntev, cia saib yuav ua li cas sib sau ua ke.
Kauj Ruam 1: Kauj Ruam 1: Cov Ntaub Ntawv Xav Tau
- 1 x 9V pin
- 1 x Arduino UNO
- 4x LED ua
- 1x Ib nrab khob cij
- 2x jumper xov
- 1 x Lub roj teeb nrog lub hwj chim txuas
- 1x USB hom A rau hom B.
Kauj Ruam 2: Kauj Ruam 2: Txhim Kho Cov Txheej Txheem
npaj cov khoom koj muab. tsis txhob tso lub polarity (cathode-anode) tsis yog. Vim tias nws tuaj yeem ua rau txoj haujlwm no ua tsis tiav. Node rau digital 5. Cathode rau GND.
Kauj Ruam 3: Kauj Ruam 3: Txoj Cai
txoj haujlwm no yog nyob ntawm qhov chaws tau muab. Nov yog cov cai uas yuav tsum tau xa mus rau Arduino:
const int PIN_LED = 5; // Pin PWM
void teeb tsa () {
tus pinMode (PIN_LED, OUTPUT); }
void voj () {
int nilaiAcak = random (176);
analogWrite (PIN_LED, 60 + nilaiAcak);
ncua (200); }
Kauj Ruam 4: Kauj Ruam 4: Nws Ua Haujlwm
Txoj haujlwm no yuav tsum ua tiav. Yog tias nws tsis ua haujlwm, tej zaum koj tsis ceev faj txaus. Saib ntawm Circuit lossis code.

Hlawv Bootloader Rau Hauv Arduino Nano 3.0 Clone Board: 11 Kauj Ruam
Hlawv Bootloader Rau Hauv Arduino Nano 3.0 Clone Board: tsis ntev los no tau yuav Arduino Nano 3.0 Clone los ntawm AliExpress uas tuaj tsis muaj bootloader. Kuv paub tseeb tias muaj ntau tus neeg uas nyob hauv tib qhov xwm txheej zoo ib yam li kuv, thiab tej zaum yuav ua rau kuv npau taws me ntsis thaum xub thawj! Tsis txhob txhawj xeeb, hauv phau ntawv qhia no
Yuav Kho Li Cas Hlawv Arduino lossis ESP32: 5 Cov Kauj Ruam
Yuav Kho Li Cas Arduino Hlawv lossis ESP32: Hauv daim vis dis aus no koj yuav kawm paub yuav kho koj li Arduino lossis ESP32 uas raug hlawv li cas! Qhov no tuaj yeem coj koj cov nyiaj tau los zoo heev, nrog qee yam uas koj nyiam ua.Kuv siv ob lub cuab yeej tshiab thiab lawv yog lub chaw muag khoom uas kuv tsis xav tias ua haujlwm tau zoo li pheej yig
Hlawv Cov Khaub Ncaws Zoo Nkauj: 8 Kauj Ruam
Hlawv Cov Khaub Ncaws Zoo Nkauj: nyob zoo!, Lub sijhawm no kuv yuav qhia qhia kev hlawv cov kua nplaum zoo nkauj uas siv arduino, kua nplaum, duab los qhia, kab xev, thiab cov yeeb nkab acrylic
Arduino Raws li ISP -- Hlawv Hex Cov Ntaub Ntawv hauv AVR -- Fuse hauv AVR -- Arduino Raws li Programmer: 10 Kauj Ruam
Arduino Raws li ISP || Hlawv Hex Cov Ntaub Ntawv hauv AVR || Fuse hauv AVR || Arduino As Programmer: ……………………… Please SUBSCRIBE To my YouTube channel for more videos …….. Kab lus no yog txhua yam hais txog arduino li isp. Yog tias koj xav xa cov ntawv hex lossis yog tias koj xav teeb tsa koj lub fuse hauv AVR ces koj tsis tas yuav yuav tus programmer, koj tuaj yeem ua
Atmega328P-PU Bootloader (Optiboot) Hlawv Qhia: 12 Cov Kauj Ruam
Atmega328P-PU Bootloader (Optiboot) Hlawv Qhia: Tsis tau lwm qhov Atmega bootloader hlawv giude. Tab sis lub sijhawm no kuv twv thawj qhov kev sim koj yuav ua tiav !! Qhov no yog Nick Gammons bootloader hlawv qhia rau Arduino boards
