Thanks I will give that a try when I get home tonight. But so I am clear. I need to put a Cap from a Ground pin on the Arduino to the emitter on the PNP // Or is it from the Ground real to the 5v real.
Between ground (any ground) and the 5V power line as close to the PNP as possible (touching it is good).

And what size Cap.. ( Way to much to learn, I am glad it is fun).
0.1 ... 0.22 uF, that sort of size, but only ceramic type.
