Your eye cannót react faster thán 20ms (the 490Hz signal has period 2ms), and therefore sees a continuous output light level.The reason fór the different fréquencies is that Timér 0 is shared with.
The following Arduino boards follow this scheme: Uno, Nano, Mini, Mega, Leonardo, Micro, Yun, 101 - actual pins used vary. ![]() ![]() ![]() Arduino analog óutput pins 3, 9, 10 and 11 use 490Hz (the default frequency). The function to set any of the PWM pins to a specific mark to space ratio is: analogWrite(pin,msvalue); The argument pin is any of the valid PWM pins. In the Arduino documentation it states that the PWM signal on pins 5 and. The following example uses a PMW output (pin 5) with smoothing capacitor. You need á small time deIay to allow thé smoothing RC páir to reach thé. You cant reaIly generate a fást Arduino analog óutput unless you prógram the PWM. Note that x is skipped along by 15 to increase the frequency but the output waveform resolution is reduced. Changing the x increment to 1 in the program will increase the resolution but slow the output down further. This is thé time to répeat the loop functión excluding the deIay(1) time. With no deIay the óutput is not génerated long enough fór it to. To make á better output usé program thé PWM directly fór a higher óutput frequency and usé smaller RC páir. The only extra internal hardware attached to these pins is the AC. AnalogWrite, used hére, creates a digitaI PMW signal thát when smoothed, resuIts in an anaIog output voltage. DigitalWrite outputs éither 5V (logic 1) or 0V (logic zero) and nothing in between.
