Tell us about yourself!
I have this issue too, looking for a workaround
What is the difference between your relay module and this one? other than the obvious 2 additional channels?http://www.microcenter.com/product/437826/4_Channe...Can I use it in the same fashion as you have without the need of additional power sources or other parts? Yours seems so simple, but I read others who used this part had to provide additional transistors and what not.
