Hey guys,
Been needing to add a basic capacitive touch switch to a project of mine. I have a gun cabinet that has a capacitive touch door hinge that is used to turn on the lights. I am making a circuit that needs to work off of the same switch (door hinge). This is running off of a ATtiny85. Right now I have the script working with a momentary push button, I just need to install the cap touch switch in its place.
I was told a 555 timer chip could possibly do what is needed, but im trying to find the best reliable solution. Any suggestions greatly appreciated.
Thanks!

 

Did a quick search and these might be helpful starting points.
