was able to write code to recieve distances from all 3 parallax ping sensors to display in terminal. worked on presentation. 

need to figure out how to get car to go in reverse. wanted to test other h-bridge because i thought my code should run properly.  however when i plug the spare h-bridge up. i switch 2 cables and it fried the board.  Also, the end came off the battery charger so i need to fix that as well.
