Capacitive touch sensor for Arduino

I am in a search of capacitive touch sensors. The functionalities I'm aiming at are
The capacitive touch should be able to recognize up, down and sideways slides on the Grid. Has anyone used the this type of module? If yes please do suggest me. Thanks in advance...!!
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
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..!!
I have made a custom board with Atmega328P SMD IC and now I am having a problem flashing it. I have flashed multiple chips like these earlier, however this time I am having a hard time figuring out the issue.
I am using Arduino UNO as an ISP programmer to burn bootloader but getting responses like Attempt 1 of 10 - stk500() is not responding etc., like that. I need some help regarding this issue.
Any kind of help will be greatly appreciated. Please ask me for any additional information that I might have not mentioned in this post.
Thanks in advance.
I have been facing this problem recently while I run the program the output terminal just shows scanned text and the android virtual device is not opening. I have reinstalled the SDK but the problem still persist.!
Hi, I was looking for a reliable carbon monoxide sensor, I tried the MQ7 sensor, but it has a preheat time of 48 hours and a sensitivity range from 20ppm-2000ppm, and my application requires 1ppm to 1000ppm. let me know if anyone working with a similar sensor or use case!
@milanvarghese No, the battery comes into the play only if there is no power from the solar cell. It's like inverters in our home. They activate only if main power is gone, rest of the time they keep charging. similarly here the direct power will be coming from the solar cell, only if the solar cell can't produce enough voltage battery comes into the loop and starts providing voltage to our circuit.
@kowshik1729 I have seen this, but doesnt it damage that battery? dischargeing and charging at the same time?
