24 October '17- Day 17- Pointers in function references & Joystick and robot car

Day 17 of class began with the lab involving the use of a joystick to control the robocar we had worked on previous to utilize a motor control board.  once both motors were hooked up to the drive line on the car it was a simple task to connect the wires to the motor control board.  The tricky part became trying to figure out which wire was going to move the motors in unison or opposite directions.  A little bit of testing out each motor by applying a voltage for a short moment, we took note of the direction of the motor spinning in order to hook them up correctly.
After ab we began lecture which introduced then use of pointer in function references.  Character strings were also discussed and how they can used in cryptography and pattern recognition software.
