This tutorial shows how to generate PWM signals with ESP8266 NodeMCU using Arduino IDE. As an example, we’ll dim the LED brightness by changing the duty cycle over time. PWM signals on ESP8266 have 10-bit resolution. To generate a PWM signal on the ESP8266 pins with Arduino IDE, use analogWrite(pin, value). The value is an integer betweenContinue reading “ESP8266 NodeMCU PWM with Arduino IDE – Dim LED (Analog Output)”
