Analog output analogWrite(pin, value)enables software PWM on the given pin. PWM may be used on pins 0 to 16. CallanalogWrite(pin, 0)to disable PWM on the pin.valuemay be in range from 0 toPWMRANGE, which is equal to 1023 by default. PWM range may be changed by callinganalogWriteRang...
Well, selecting one of the 8 analog inputs will require 3 GPIO pins. For many applications, that should not pose a problem when using the ESP8266-07 or -12. These versions have 7 easily accessible GPIO pins available, leaving you with 4 GPIO pins for any digital input or output requirem...
