This project demonstrates input/output (I/O) port interrupts of the M430G2553 chip using a 28BYJ-48 5V stepper motor, a ULN2003 darlington sink driver (motor driver), 2 LEDs, 2 de-bounced push-buttons, 3 normal push-buttons, an LM317L adjustable voltage regulator, and a 9V battery to design a washing machine application on a breadboard.
This washing machine application is from chapter 9 of the book ‘Programmable Microcontrollers with Applications using the MSP430 Launchpad’ by Cem Unsalan and H. Deniz Gurhan.
I’ve migrated this project from the Launchpad to a breadboard and modified the code and hardware. I’m using the M430G2553 chip. I added an LM317L adjustable voltage regulator to give the chip power on the breadboard via a 9V battery. I added a RESET button. If you have any questions let me know and I’ll try and answer them as best I can 
Enjoy!
