The package includes:
- tested Grade crossing module
- 2x TCRT5000 infra sensors
- 2x 9g micro servos with 3 different arms
 
Description:
When the crossing grade is free the warning LEDs are off, the flashing white LED indicates free grade crossing (optional).
As the train covers the sensor the red lights start flashing and the relay activates the Sound module. After 3 seconds the gates come down slowly - servos are active.
Keep flashing until the sensor stay uncovered for at least 1,5 seconds (the last wagon leaves the sensor), then the gates come up, the warning lights and sound will go off.
 
Manual control:
You can add any kind of pushbutton to operate sequences. Sensors are not working if the sequence has been activated manually.
 
Additional option:
The module has 2 universal outputs (5V/500 mA). If you wish I can customize these outputs to your wishes (another light, relay) before ordering!
