Train Horn Synthesis with the MSP430FR2000

I needed to generate a jarring sound for a silly reason. This project started like many other projects with a trash find, a PA speaker that was just begging to be rescued and reused. Slowly this project evolved from a simple weekend or two Arduino based solution to the four week solution that I present to you below. Like many of my projects I used this particular one as a learning experience for programing and embedding a microcontroller from the MSP430 family of microcontrollers. In between the start and end of this project I also learned about sound generation using PWM and train horn chords.
