/************************************************************* Download latest Blynk library here: https://github.com/blynkkk/blynk-library/releases/latest Blynk is a platform with iOS and Android apps to control Arduino, Raspberry Pi and the likes over the Internet. You can easily build graphic interfaces for all your projects by simply dragging and dropping widgets. Downloads, docs, tutorials: http://www.blynk.cc Sketch generator: http://examples.blynk.cc Blynk community: http://community.blynk.cc Follow us: http://www.fb.com/blynkapp http://twitter.com/blynk_app Blynk library is licensed under MIT license This example code is in public domain. ************************************************************* This example runs directly on NodeMCU. Note: This requires ESP8266 support package: https://github.com/esp8266/Arduino Please be sure to select the right NodeMCU module in the Tools -> Board menu! For advanced settings please follow ESP examples : - ESP8266_Standalone_Manual_IP.ino - ESP8266_Standalone_SmartConfig.ino - ESP8266_Standalone_SSL.ino Change WiFi ssid, pass, and Blynk auth token to run :) Feel free to apply it to any other example. It's simple! *************************************************************/ /* Comment this out to disable prints and save space */ #define BLYNK_PRINT Serial /* Fill-in your Template ID (only if using Blynk.Cloud) */ //#define BLYNK_TEMPLATE_ID "YourTemplateID" #include #include #include // You should get Auth Token in the Blynk App. // Go to the Project Settings (nut icon). char auth[] = "API Key"; // Your WiFi credentials. // Set password to "" for open networks. char ssid[] = "ssid"; char pass[] = "password"; Servo servo; BLYNK_WRITE(V3) { int out=param.asInt(); if (out==1){ servo.write(160); } else if(out==0){ servo.write(30); } } void setup() { // Debug console Serial.begin(9600); Blynk.begin(auth, ssid, pass); servo.attach(2); // You can also specify server: //Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 80); //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080); } void loop() { Blynk.run(); }
