Touch Sensor (using an analog input port)
A capacitive touch sensor using an analog input port.
The application note describes the design of a simple capacitive touch sensing method based on the LPC1100 microcontroller from NXP Semiconductors.
We can also use the method with LPC1768 and the mbed platform.
I implemented the library for the touch sensing method.
You can enjoy the touch sensing interface with only three components.
Please see the datasheet and the pinout.
