yeah....sorry for that...i am new here....i am an B.TECH final year student.....i am trying to work on touch technology myself....
this is my circuit diagram in proteius. i tried by burning the code in this but i do not know about the exact digital value after a touch is made
and one more thing when we talk about the actual hardware i studied that the touch sensor is connected to one or more adc channel. the second channel is continuously scanning and connected to vdd or ground untill the touch is mot made through first one.......can u please explain how?????
