Texas Instruments EK-TM4C123GXL Garage Door Opener:-
=====================================================
This is a Hardware based project by which we can make a Cortex-M4 Garage door opener.
This project has three controlling switches, who's description are given following: -

1- Author and revolutionbug will not be responsible in case of any mishap, damage or loss.
2- For RELAYS & MOTOR connections, please concern "diagram" figure attached with the project.
3- Up & Down sensors are gate switches which protects the motor from over current and shut down the system.
