Problem Statement

• To design and build an automated driving range
  that will improve the ranges efficiency and user
  friendliness.

4
BACKGROUND

• A typical driving range consists of a range mat
  and a rubber tee.
• The golfer pays for a bucket of balls from an
  attendant at the front desk.
• The golfer will manually tee up each golf ball on
  the rubber tee and hit them.

5
Problem Solution

• Bill acceptor to give a signal to start the
  program
• Network of piping to hold and transfer balls to
  lifting system.
• Stepper motor, lead screw linear actuator, and
  tee to lift up golf balls.
• Light / Dark Sensor to determine when ball is
  present on tee.
• Sensors to start the timer and stop the timer for
  the swing speed calculator.
• 7 segment displays to inform golfer how many
  balls have been hit and how fast each swing was.

Dollar Bill Acceptor / Validator

• Only accepts 1 bills
• Less expensive (no bill changer required)
• 120VAC supply voltage
• Cost 40 used

Swing Speed Calculator (SSC)

• Requires two sensors
• Diffuse Reflective Sensors
• One sensor to starts timer in the HC08
• Second sensor interrupts the timer
• Unsure About Completion By Week 12

12
Swing Speed Calculator

• Use the Timer Interface Module (TIM) on HC08
• Use External Interrupt (IRQ) as input to capture
  sensor 1
• Use Keyboard Interrupt Module (KBI) as input to
  capture for sensor 1
• Configure IRQ KBI to capture on rising edges
