Potentiometer and speaker circuit with Arduino
This example shows how to read a potentiometer using the Arduino and use its value to change the frequency of a sound coming out of a speaker.
Open the Serial Monitor window in the Arduino software to view the debugging messages output by the program.
- The speaker is connected directly to power and ground... Isn't that a short circuit and therefore dangerous?
- The sound produced by this circuit is not very loud. What would you have to do to get the sound louder?
- Are we having fun yet?
