I’m using the Arduino IDE to flash the Soil Moisture Sensor. I can’t seem to turn off the LED on GPIO13. Anybody had any experience with this? Here’s the code I’m using:
const int Led = 13; // D7
pinMode(Led, OUTPUT);
digitalWrite(Led, LOW);

I tested the sketch and it works fine

ESP8266 BlinkWithoutDelay by Simon Peter
Blink the blue LED on the ESP-01 module
Based on the Arduino Blink without Delay example
This example code is in the public domain
The blue LED on the ESP-01 module is connected to GPIO1
(which is also the TXD pin; so we cannot use Serial.print() at the same time)
Note that this sketch uses LED_BUILTIN to find the pin with the internal LED

else

digitalWrite(LED, ledState);
