ESP8266 Robotics Projects

Listing 1-1 – Blink a LED

Using your Arduino IDE, type the code as shown in the Listing 1-1:

#define ESP8266_LED 2
    
void setup() 
{
  pinMode(ESP8266_LED, OUTPUT);
}
    
void loop() 
{
  digitalWrite(ESP8266_LED, HIGH);
  delay(500);
  digitalWrite(ESP8266_LED, LOW);
  delay(500);
}  

Then, verify the sketch by clicking on the Verify button. Finally, upload the program by clicking on the Upload button. This will take a few seconds to complete. After completing the flashing, the LED will start to blink.
