    I am having problems with making PIC10F206 to be stable in my circuit.
    I have programmed the PIC and made the circuit,and it works.
    But there is 1 tiny problem.I can sometimes trigger the input of the PIC by touching it.Input is pulled down via 10K resistor.By touching I mean I have connected a wire to my circuit which is running to PIC input via voltage regulator 12V-5V.Input should be triggered by 5 volts.

    Kind regards,

    I don't follow what you say.

    Do you have a schematic?

    What part of the circuit are you touching?

    Touching with your finger or this wire? (I'm not sure what this wire connects to either.)

    I am also doing a project on mTouch based on this chip. On the contrary, the sensitivity of the touch pad is adjustable by changing the variables in the software.

    If your circuit input is too sensitive, you can try to make the wire as short as possible or add a 100nF cap to Ground parallel with you 10K on the input.
