ESP32: Blink the LED (ESP32 + Arduino series)

It's the "Hello World" of IoT projects: blink an LED. Here, I'll show you how to blink the built-in LED of most ESP32 development boards. Of course, by using Arduino framework.

WOW....you have just saved my day! Followed the steps and my board is blinking. I now know its connected and takes programs. A++ for this video. Thanks a bunch

Thx, just starting with ESP. Helped a lot! Deserves a like :D

Thank you. Just what I needed to figure out pinouts.

After spending hours to pull my hair, I realized the cable I was using was not able to transfer data and was not visible as /dev/ttyUSB0. Make sure you have a correct cable...

Thank you for the tutorial video!

 For 'ESP-WROOM-32', I had to keep the 'boot' button on my board pressed while flashing the program; otherwise the flashing process gave an error "Failed to connect to ESP32".

no, it didnt work, in my case (esp32 wroom_v1)
this is what worked for me:
int LED_BUILTIN = 2;
void setup() {
pinMode (LED_BUILTIN, OUTPUT);
}
void loop() {
digitalWrite(LED_BUILTIN, HIGH);
delay(1000);
digitalWrite(LED_BUILTIN, LOW);
delay(1000);
}

What do you mean with HIGH to turn off but LOW to turn on? I'm confused and not sure if i should switch to ESP if it is this unintuitive...

[komalshah]

How do I make it stop it just keeps blinking

[moatez]

bro u sayed turn off and you used high -_-
