Capacitive touch sensor for Arduino

[Akhil]

This can be done using captive grid. You can buy a touch pad

or you can make your own PAD

please refer 13th page of this documentation.
if you like to make one MPR121 is a nice choice

@kowshik1729
Design C is also good,

@Akhil Thanks. I am not in a state to design my own capacitive touch so I am going with already made modules. But the one which you have posted is too very expensive for my application. Are there any other modules that are a bit more cheaper.

Hey @kowshik1729, why don't you use a five of the touch keys(shown below), form them up in the shape of a cross and get the sequential data across two of those sensors to detect a left/right or up/down swipe?

@SuperGops Woow that's a great idea...I shall try this out..!!

@kowshik1729 That is also Nice idea, If you want only Up,Down, Left, Right movements then try this method suggested by @SuperGops
