ESP8266 Robotics Projects

Writing the Arduino UNO sketch

First, generate the Arduino UNO sketch that shows how to read values from virtual pins with the Adafruit HUZZAH and ESP8266 Wi-Fi by using the Blynk Sketch Builder (https://examples.blynk.cc). The following instructions will show you how to generate the example sketch with the Blynk Sketch Builder (Figure 4.9):

1. Select Adafruit Huzzah from the Board drop down list.
2. Select ESP8266 WiFi from the Connection drop down list.
3. Type the Auth Token associated with your Blynk app in the Auth Token (optional) text box.

4. Select Virtual Pin Read from the Example drop down list:
