Hi,

Code: Select allanalogWrite ( led, 1000 );

the max value for analogWrite is 255. Try this:

Code: Select allanalogWrite ( led, 255 );

Code: Select allanalogWrite ( led, 1000 );

Works for me. And no wdt reset.

Code: Select all

int led = 15;

void setup() {
pinMode ( led, OUTPUT );
digitalWrite ( led, 0 );
}

void loop() {
analogWrite ( led, 1 );
delay(1000);
analogWrite ( led, 1000 );
delay(1000);
analogWrite ( led, 512 );
delay(1000);
analogWrite ( led, 255 );
delay(1000);
}

I would try putting WiFi.disconnect(); at the top. Do you have wdt resets when you run any other code? Maybe you have poor power supply regulation on the 3.3V line.
