When subjected to an alternating electric field, a piezo ceramic material disc inside the buzzer is caused to stretch or compress, in accordance with the frequency of the signal thereby producing sound. Buzzers are widely used in computers, alarms, toys, telephone and so on. For this project 4Duino resistive touch display is used as a means for a graphical user interface to play the piano.

Jumper cables
Micro USB cable
µSD card

Implementation Step 1 : Build

Build the circuit as shown in the following diagram and schematic.

Step 2: Program

Workshop 4 – 4Duino Extended Graphics environment is used to program this project.

This project requires the Arduino IDE to be installed as Workshop calls the Arduino IDE for compiling the Arduino sketches. The Arduino IDE however is not required to be opened or modified to program the 4Duino.

Open this file using Workshop 4.

Step 3: Comms Port

Connect the 4Duino to the PC using µUSB cable.

Then navigate to the Comms tab and select the Comms port to which the 4Duino connected.

Step 4 : Compile and Upload

Finally, go back to “Home” tab and now click on the “Comp’nLoad” button.
