Abstract
An improved claw control system for use in a coin operated crane game. In one embodiment, this system allows operation of the claw solenoid in a precise manner in which the DC claw current is digitally controlled. A microcomputer can be used to read a potentiometer setting via an analog to digital converter. The microcomputer outputs a command current to the solenoid via a digital to analog converter and a solenoid driver.
