 Bend and cut the LED leads to the correct shape and length. Solder the LED and cable before gluing the module into the enclosure.

+The LED should be connected between LED and GND, with a 120R series resistor. To avoid damaging the LED, use hot-melt glue to secure it in place (not cyanoacrylate).

+The piezo should be connected between PIEZO and VCC (green). The piezo may be secured with cyanoacrylate or hot-melt glue, but try to give the disc some freedom of movement or the sound output may be reduced.

 Test the reader and controller together before securing the reader to the wall with double-sided adhesive foam tape.
