Sound/Tone Generation! For Sound People (optional)
An analog output, different from the light dimmer. To make a varying sound, you would want to change the frequency of the output signal, not the amplitude.
- This is more like the light blinking from part one, where changing the input voltage will change the rate of the light. But now you will do it with a Piezo, adjusting the time delay in microseconds.
- If you like sound, try this: http://www.arduino.cc/en/Tutorial/PlayMelody, I have a piezo you can use. (Or you can get one at RadioShack).
- This example adjusts the frequency of the output (tone) not the magnitude.
- the light fading above (
analogWrite()
) adjusts the brightness of the light (magnitude) with PWM.
