Auto-Drive Functional Breakdown

 

                  1)  System takes in $1 bill from user using dollar bill acceptor

               - Bill acceptor will verify that a $1 bill has been detected

               - Bill acceptor will send signal (impulse) to HC08

               * Using a Dixie-Narco Upstack Dollar Bill Acceptor (only accepts $1 bills)                      

 

       2)  System tees up golf balls for the user

               - HC08 sends data to linear actuator to raise golf ball

               * Linear actuator will consist of a stepper motor and acme screw

 

       3)  System detects if ball is present at tee

               - Using light sensor inserted in the tee to detect presence of ball

               - The sensor will send signal to the HC08 if a ball is not present

               * Using light sensing resistor and comparator

 

        4)  System tells user how many balls remain to be hit

                - HC08 will know the user has 10 balls to start with

                - The number of balls remaining will be displayed on seven segment displays

                - When the light sensor in part 3 detects a ball is not present, it will

                   subtract one from the starting number of balls.

                -  When the counter reaches zero, the system will go into standby and wait

                    for another dollar to be inserted

                * Using a ICM7217M LED display drive & seven segment displays

 

         5)  System will display the club head speed

                 - HC08 will use Diffuse Reflective Sensors to start the timer and stop the timer

                 - HC08 will use the difference in time to calculate the club head speed in mph

                 - The club head speed will be displayed on seven segment displays

                 * Using a ICM7217M LED display drive & seven segment displays

 

         6)  System will have capability to store 500 golf balls

                 * Using a network of PVC piping and 90 degree street elbows

 

         7)  System will have encasement to store network of PVC piping & electronic

              components

                  - Used for weather protection and dollar bill acceptor security

                  * Made from wood, sheetmetal, and angle iron

 

         8)  System will have platform for user to stand on and store linear actuator

                   * Will have bracket to hold linear actuator

                   * Made from wood and metal
