DIY Capacitance touch button with PIC and Frequency Change

[ALLTENCH007]

Hello, I am looking for abit of help.  I am creating a capacitive touch system with blue and Red LED'S that light up when touched. This is for a friend who has a disabled child, and it is going to be a learning aid for them. hav 2m of blue LED's and 2m of red LED's + x8 AA cells. I ned to create x2 capacitive touch pads that are 20x20cm and when the system is on the Blue LED's are lit up when either of the pads are touched, it changes to Red LED's on, and blue off, so it basically switchesLED'?

You could add this to your door lock actuation system so that you no longer need to 'pull' the door to make contact with the foil tape, yes?

@ixamraxi yes indeed, and that is how i had originally designed it. But when the PIC falls into sleep, the current drawn was quite larger than the 15uA that draws now, because timer 1 and 2 had to remain open and running. That is why i used this mechanical switch instead. Only for technical reasons. The original design had a large proximity switch.
