Hi community,
I want to build a "touch" light switch... you know that lamps that start to glow if you touch them....
Therefore i build a oscillating circuit with an inductor (0,1 µH) and a selfmade capacitor. The capacitor is selfmade as i wish to use it as my switch. I installed that the sensors to my Arduino Due which works fine. I meassure the counts by a timer and if i reach a threshold value the light turns on.
Now i wanted to build 4 switches which work sepperated from each other.Still everything works fines until i connect my selfmade cappacitors to my circuit. Now the signals are getting mixed up. If i touch cap one all lights turn on.
Now my question: why runs the system nice when the cappacitors are not installed... and why does it mix up the signals if they are connected?
Could anybody help me ?
Thanks a lot !!!
PS:
-Timers run correct
-Setup works fine without Cap.
-Single sensor with Cap works fines as well
-Problem starts when 2-4 sensors are connected
