Is there an external led for NodeMCU ESP8266?

No external component is required. On Board LED for ESP8266 is connected wtih GPIO2. This code is to blink built-in LEDs of NodeMCU. The on-board LED of ESP8266 is connected to GPIO2 and ths LED on NodeMCU board is connected to GPIO16. Working of this code is same as we explained earlier for external LED blinking with NodeMCU.

Is the ESP8266 led connected to the gpio2?

The on-board LED of ESP8266 is connected to GPIO2 and ths LED on NodeMCU board is connected to GPIO16. Working of this code is same as we explained earlier for external LED blinking with NodeMCU. So far we have seen how to program and blink an LED with NodeMCU.

Can you use ESP8266 to blink LEDs?

This code is to blink built-in LEDs of NodeMCU. The on-board LED of ESP8266 is connected to GPIO2 and ths LED on NodeMCU board is connected to GPIO16. Working of this code is same as we explained earlier for external LED blinking with NodeMCU.

How are the LEDs on a NodeMCU connected?
