Arduino and PWM
The Arduino IDE has a built in function “ analogWrite() ” which can be used to generate a PWM signal. The frequency of this generated signal for most pins will be about 490Hz and we can give the value from 0-255 using this function. analogWrite(0) means a signal of 0% duty cycle. 17 déc. 2018
