Generell
With this measuring device the actual speed can be determined.
Application
Lightning: Fast vehicles are indicated by the "speed trap".
However, no radar beam is used for measurement.
(The circuit can also be used without display)
Speed display: Like on some school roads, an display can be placed beside the road
Technology
The "flash light" is triggered by minus.
You can setup a Servotiny or a speed-dependent Servo junction.
Fast vehicle drive straight forward, slower to be diverted to the parking lot or gas station
Function
The time is measured with 2 Sensors, Light barriers, Feedbacksensors#Reedswitches or Hallsensor what
the vehicle need to drive about 15cm. The sensors must switch to minus.
Setup
|
2 Jumpers are used to set the scale: H0, TT, oder N |

Additional Parts
Two Seven-Segment Display with common anode. They are available in different sizes.
Every segment has its own anode which are connected to the one, ten, and hundreds contact of the plate.
