I made a bed side lamp out of a 3W led. touching the metal base of the lamp turns it on, a second touch dims it, a 3rd dims more and a 4th turns it off.

All I used is an 8-pin 12F683 to do MIBAM for the dimming and just the stock standard built in ADC to do the touch sensing.

After a little calibration, ive been using it for nearly a year and have never had a false triggering of the touch sensor.
