Summary of ELECTRONIC PIANO USING PIC MICROCONTROLLER (PIC18F4550)
This article describes an electronic piano project built using the PIC18F4550 microcontroller. It details how 11 buttons generate specific musical frequencies (A4 to D5) by outputting square waves through a speaker connected to pin RA0. The system relies on the mikroC Sound_Play library for software implementation, utilizing delay functions to control tone duration and pitch.

Crafted with only the software you don’t have source code mikroC hex, but given the information needed for sound Sound_Play library used mikroc
For example, B1 button;
Audio output 440 Hz square wave. To do this, 440 Hz duration 1/440 = approx 2272 mS equal to. After the delay (1136 mS) “1” output, and then exit the “0″, do (you can google translate minor errors with the statement that it will solve the situation inceleyinc the sample code mikroC people dealing with) each of them is used to produce different frequencies of sound.
