So if you are crazy enough to want to build your own combination uno driving a bally AS-2518-23 lamp driver board and separate Zero crossing detector here is a simple sketch to test your devices are working copy and paste the following into your arduino ide...
/* ======================================================================================================
*ZeroCrossTest.ino
*Feb 2, 2019 Todd Legere
*Purpose: Test arduino communicating with bally AS-2518-23 lamp board and Zero Cross Detector
* Arduino built in LED lamp will flash every 1/2 second to show that Zero Cross detector working
*Open the serial console and choose which lamp pin to turn on.
*By default lamp one on at startup
