Hauv qhov kev qhia no koj tuaj yeem tswj hwm koj lub servo siv Blynk app hauv IOT Platform
Kauj ruam 1:
Hauv qhov kev qhia no koj tuaj yeem tswj hwm koj lub servo siv Blynk app hauv IOT Platform
Hauv qhov haujlwm no koj yuav tsum tau kho vajtse
1. Nodemcu
2. Servo
3.connection ware
Software
1. Ardunio
2. Blynk App
Qhov kev qhia no kuv faib ua 4 Tshooj
Ntu 1: NodeMCU rwb thaiv tsev nrog lub npe wifi thiab tus password
char ssid = "Koj lub npe WIFI";
char pass = "Password";
Piav qhia: suav nrog Lub tsev qiv ntawv Wifi thiab lub npe wifi thiab tus password uas koj tau siv los siv internet
Ntu 2: Blynk App Xaiv
#suav nrog
#define BLYNK_PRINT Serial
char auth = "yourAuthkey";
Piav qhia: suav nrog blynk app lub tsev qiv ntawv thiab rov ua dua koj tus lej tseem ceeb los ntawm koj gmail
Ntu 3: Kev ua haujlwm servo
#suav nrog servo.h
Servo tsav 1;
#define servo1Pin D2
Piav qhia: suav nrog lub tsev qiv ntawv servo thiab Tsim Servo thiab npe nws "servo1" thiab Txheeb NodeMCU tus pin txhawm rau txuas Servo
servo1.attach (servo1Pin);
Piav: NodeMCU (A0) los ntawm 0 txog 3.3V. Sab hauv, 10 khoom ADC (Analog-Digital converter) yuav tsim tus lej digital (txij 0 txog 1023),
servo1Angle = daim ntawv qhia (PotReading, 0, 1023, 0, 180);
Piav qhia: Peb yuav tsum "daim ntawv qhia" tus lej digital no, txhawm rau kom Pulse Width Modulated (PWM) digital output ntawm tus pin D2, yuav txawv ntawm 0 txog 180 (servo1Angle). thiab Nrog lub teeb liab no, servo yuav tig los ntawm 0 txog 180 degree, siv cov lus hais hauv qab no.
Kauj Ruam 2: Ntu 4: Tsim Blynk App los Tswj Cov Duab Ua Haujlwm
Downlode Code Nyem qhov no
1. Intoduction rau nodemcu8266 & Cov Kauj Ruam rau Ntshuam ESP Pawg Tsev Qiv Ntawv 2. NodeMCU8266 Basic Project-Blink a LED
3. NodeMCU8266 Digital Nyeem (Push Button)
4. Analog Cov ntaub ntawv nyeem siv NodeMcu8266
5. NodeMcu LED tswj Siv hauv Blynk app hauv IOT platform
6. NodeMcu rau DHT Interface hauv Blynk app | Ntawm IOT Platform
7. Txoj Kev Zoo Tshaj Plaws rau nodemcu gps tracker blynk app | hauv IOT platform
8. NodeMCU RGB LED | Rau cov pib tshiab

Ib IoT Halloween Pumpkin | Tswj LEDs Nrog Arduino MKR1000 thiab Blynk App ???: Nyob Zoo Txhua Tus, Ob peb lub lis piam dhau los yog Xus thiab ua raws li kev coj noj coj ua kuv txiav tawm lub taub dag zoo rau kuv lub sam thiaj. Tab sis muaj kuv lub taub dag sab nraum zoov, Kuv pom tau tias nws yog qhov txaus siab heev uas yuav tsum tau tawm mus txhua hmo kom taws tswm ciab. Thiab kuv
IoT Base Platform Nrog RaspberryPi, WIZ850io: Platform Device Driver: 5 Kauj Ruam (nrog Duab)
IoT Base Platform Nrog RaspberryPi, WIZ850io: Platform Device Driver: Kuv paub RaspberryPi platform rau IoT. Tsis ntev los no WIZ850io tau tshaj tawm los ntawm WIZnet. Yog li kuv tau siv daim ntawv thov RaspberryPi los ntawm Ethernet SW kev hloov pauv vim tias kuv tuaj yeem lis tus lej yooj yim. Koj tuaj yeem sim Platform Device Driver los ntawm RaspberryPi
