Flashing A0

1. Connect A0 to your computer via a micro USB cable

2. Select "ESP32 Dev Module" as board type.

3. Upload a sketch. An easy sketch to adapt is the "Blink" sketch found in File>Examples>Basics>Blink.

4. Change the three instances of "LED_BUILTIN" to "13":

    void setup() {
    // initialize digital pin LED_BUILTIN as an output.
    pinMode(13, OUTPUT);
    }
   ​
    // the loop function runs over and over again forever
    void loop() {
    digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
    delay(1000);                       // wait for a second
    digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
    delay(1000);                       // wait for a second
    }

5. Press upload and the LED will blink every 1 second! 💡
