Microprocessor-controlled lap counter for model car race tracks with optoelectronic scanning

摘要

the lap counter employs contactless optoelectronic sensing which generates electrical sensing pulses which are processed by a microprocessor. A freely programmable controller is used which provides the choice of several options. One option is to count the number of laps with a freely selectable lap requirement and final victor determination. Another option is to measure the time or speed.
