DSC04910 IR detec

IR detector for marble track.
This detector can be inserted anywhere on the existing marble track. It has the dimensions for the Fischertechnik blocks. The detector works with an IR led and a photodiode as receiver. The 3D print housing is made in such a way that it shields the ambient light as much as possible. If necessary, an extra cover can be mounted afterwards on top. It has 5 mounting possibilities for optimal environmental suppression. The resistance values are given for 5V. If 9V is desired, the values can be increased slightly. The current values will also work at 9V but the current is higher. I use my regular 3 pin connection: output, VCC, GND. Because there is a pullup resistor you have to take into account that the output voltage will have the same value as the installed VCC. Therefore, do not use 9V where the output should be 5V max!
