Blynk IoT App with Arduino Uno R3, ESP8266 ESP-01 Module, Blynk Cloud and 4 x LED - Tutorial
Learn to create a 4-LED IoT device using Arduino Uno R3, ESP8266 ESP-01 module, and Blynk IoT (2.0) in this comprehensive 40-minute tutorial. Begin with an introduction to the project and review the Fritzing diagram. Explore the necessary components and learn how to set the UART/Baud Rate of the ESP-01 module. Follow step-by-step instructions for building the device, signing up for a Blynk Cloud account, and creating templates for datastreams and dashboards. Set up the mobile dashboard using Developer Mode in the Blynk IoT smartphone app. Develop code for the IoT device using Blynk Example Browser and Arduino IDE, and create a new device on Blynk Cloud. Install the required Blynk Library in Arduino IDE, upload the code to your device, and test the WiFi/Blynk connection. Finally, verify the functionality of your IoT device using both the Blynk IoT app and Blynk Cloud web dashboard. Includes important links, resources, and notes on SDK compatibility for the ESP8266 ESP-01 module.
