WebFeb 8, 2012 · You are correct. You can't use both functions on the same pin. The two functions analogWrite and tone both attempt to control the pin with a PWM signal. Doing both in sequence changes their defaults. For analogWrite, the tone is 490Hz. WebTone is a more specialized function created to work with speakers and buzzers. You supply it with a pin argument and a frequency argument measured in hertz. Using a method …

WebWrites an analog value ( PWM wave) to a pin. Can be used to light a LED at varying brightnesses or drive a motor at various speeds. After a call to analogWrite(), the pin will generate a steady rectangular wave of the specified duty cycle until the next call to analogWrite() (or a call to digitalRead() or digitalWrite()) on the same pin. Board. WebApr 25, 2014 · This means that every time tone() is called on the Esplora, timer 3 is reconfigured for CTC (WGM3[3:0]=0b0100), whereas the red component requires PWM in order to be used properly (and analogWrite() specifically uses 8-bit phase-correct PWM [WGM[3:0]=0b0001]). And since the timer is required until the tone stops, there's no …

WebMay 5, 2024 · I use non-interfering pins for tone() and analogWrite(). On my Leonardo, I choose 6 and 9. See the tone() reference, tone() - Arduino Reference, for more info.
