    Hi,

    Need a help with my project. I have made a touch sensor based on AT42QT101X sensor. it has an OUT, that gives 5V+ and max 20mA.
    Currently there is a LED (with resistor), so when I touch the sensor, the LED turns on.
    I need to convert it this way, that when I touch the sensor, the OUT signal would act as a push button, like shown here:

    So I was thinking can it be done with transistors or anything else?
    Mby the "analog switch" would work?
