Welcome MRH Readers!
These devices are simple infrared sensors
that make detection of locomotives or rolling stock easy
and reliable. Just place the sensor where its invisible light beam will reflect off
the object of interest and you're done - no time-consuming or
frustrating adjustments! Based on modern silicon technology, this sensor is
tolerant of ambient (background) lighting conditions, be it completely dark or under full lights, with no false
triggering. Combined with a
discrete under-track installation, this low-profile sensor solves many of the
challenges that plague other optical detector products.
DCC Decoder Shield for Arduino
This board is an optoisolated interface shield for connecting an
Arduino (as a decoder) to a model railroad DCC control system. The
board has provisions for sending a DCC ACK pulse, connecting I2C
accessories and general purpose I/O lines, as well as optionally
powering the Arduino from DCC power and providing up to 400mA of 5VDC to
