      Hello,

      Your problem reminded me of the problem I had when I first started using the
      UVTron. On the standard driver board output 2 goes low for only ~10ms for
      each pulse detected. This time was too brief to be detected by the
      HandyBoard that I was using at the time. If you add an electrolitic
      capacitor to the board at location marked CX observing correct polarity the
      pulse width of the signal can be extended. A 1uF capacitor will extend the
      time to 1 second but I found that a .47 uF capacitor extended the signal to
      about half a second and was more than sufficient to read it.
