Arduino Program for Smart Blind Stick: Once we are ready with our hardware, we can connect the Arduino to our Computer and start programming. Any pin works just fine, but my code has been written for Pin 11. But a passive buzzer does not have such source, so it will not tweet if DC signals are used; instead, you need to use square waves whose frequency is between 2K and 5K to drive it. The buttons are connected to the Arduino A0 pin through a voltage divider, and can be checked via a simple analog reading. A duration can optionally be specified, otherwise the wave continues until the stop() function is called. Setup: The tone generation is mainly based on the „tone (x, y)“ command, the x value indicates the pin to which the positive contact of the loudspeaker is connected and the y value indicating the pitch. You can actually do without the 1 k ohm resistor! If you connect without the resistor, the buzzer will be a lot louder, and the sound quality might degrade. By default, the library is configured to use the pin number 4. Today I found a complete post on how to play Super Mario Bros theme song on a piezo buzzer! It's very simple and fun, and great as a beginner Arduino project. Because the buzzer draws more current than the maximum current that an Arduino pin can deliver, it is necessary to connect the buzzer to Arduino. Connection method.
