The Speed Trap on RoboLab Cities and Transportation sets can be modified to show the time
a vehicle takes to go between the two photogates.
One nice thing on RoboLab 2.5.4 is ASK RCX.
It is in the pull down PROJECT menu as Upload RCX Code.
The 10 students today modified the program to just exactly read Red when the walker went through.
Many ideas were needed.
Some timed by clock. Some worked on Interrogate RCX.
Many ideas were checked until it worked perfectly.
