optical detector module
Analog signal measurement of 2 fast consecutive marbles. The pulse duration of a marble is about 17 msec, the minimum distance between 2 marbles is about 47 msec. If the marbles are supplied from the transport chain, the time between 2 consecutive marbles is much longer, around 2 sec. The speed is then determined by the motor and the number of teeth between each magnet holder.
This measurement indicates that you need to be able to process a pulse of at least 15 msec in the TXT-Controller. These signals are measured at the top of the input of the module where the IR detector is located.
