On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED pin independent of which board is used. If you want to know what pin the on-board LED is connected to on your Arduino model, check the Technical Specs of ...
The LED_BUILTIN (L) is connected to digital pin 13 of the board. When this pin is HIGH, the LED is on, when the pin is LOW, it’s off. You can also use the constant LED_BUILTIN in your code, e.g. when using digitalWrite(pin, value)....

- Use the onboard LED. - Note: Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED pin independent of which board is used. ...
Display — Measures the analog voltage of an Arduino board pin. Push Button — Toggles the status of an Arduino onboard LED. The Push Button block enables you to use the touch-screen interface of an LCD display to toggle the LED status.Prerequisites...

When Pin 7 (key pin) on the Arduino is pulled low, the board will send a pairing command to Tuya’s module. When the module receives this command, the onboardLED_BUILTINwill flicker, indicating that the module enters the pairing mode. Then, use theSmart Lifeapp to pair with the module...
LED is on but the pin 13 LED is not flashing, it could be that the factory code is not on the chip; follow the instructions inRecipe 1.3to load the Blink sketch onto the board to verify that the board is working. If you are not using a standard board, it may not have a built-...
