23:10 <Asure>: Bottom line, first part : HIGH and PULSE will be lit if the signal is like this.

23:10 <Asure>: Bottom line, second part: LOW and PULSE will be lit
23:11 <Asure>: also the flat line between the pulses is not 0 volt (GND)
23:12 <Asure>: if you put a probe on GND it will be a clean LOW signal. also on +5V it will be a HIGH signal
