Summary of HAPPY BIRTHDAY using PIC12F629 Microcontroller
This article describes a DIY Happy Birthday musical card project using a PIC12F629 microcontroller. It emphasizes simplicity, requiring only four components and a prototype PC board to teach programming skills. The circuit relies on a piezo diaphragm connected to specific pins, with the melody generated entirely by software. Users must burn the provided .hex file or use the .asm file for compilation.
Parts used in the Happy Birthday Musical Card:
- PIC12F629 Microcontroller
- Piezo diaphragm
- Prototype PC board
- Programming cable (implied for burning the chip)
Why spend $10.00 on a Happy Birthday musical card when you can produce the tune yourself.
This project uses just 4 components and a small prototype PC board to produce a project that will teach you a lot about programming.
The circuit uses a piezo diaphragm connected to pins 3 and 5.
That’s the only component.
All the work is done by the program.
The project is so easy, we don’t need to provide any construction details
Here are the files:
HappyBirthday.asm
HappyBirthday.hex
Here is the program.
You must use the .hex file to “burn” the chip or the .asm file as these are laid out so that the compiler and programmer can understand the data.
The following program is just for viewing.
