I work with a group of driving instructors who provide driver training to public safety.
We want a device that will do the following... contain some type of sensor that senses an approaching vehicle like a traffic counter tube or a garage door sensor type device. Then when an approaching vehicle is sensed the device randomly selects one of three green lights on a post to illuminate.
The purpose is to force the driver to make a split second lane change in order to enter the section of the course indicated by the green light.
I have built small electronic projects before but always from kits, never from scratch. I humbly ask for direction what parts I should be looking for and where. I appreciate all advice.
Ideally it would be weather proof and battery powered.
I have located a viable vehicle sensor that will output 12 volts DC. Now I just need to use that 12 volts to randonly illuniate one of three lights. Please help.
