Multiple ttp223 on same power supply

[Mysterymachine]

Hey guys I have a little problem and need some help. I have ESP, ws2812 led and ttp223 sensor. If I connect one touch sensor on ESP everything works fine, but as soon as I connect the second sensor with second LED strip I can't individually control each strip, need to touch both sensors for strips to work. I suppose I need some diode somewhere for that to work or a resistor on D4 pin but to be honest dont know where to put it, also i would like to put some capacitor on each strip for faster response bur don't know which one to use (each strip has 5 LED's in it)
Thanks in advance and sorry if something is not explained well

First case that works


Second case

Where does your 5v supply come from and what is it rated at.?

Power supply is s-30-5 5V 6A, and input from it on schematic is in top right corner. Like I said everything works but touch sensors are working like AND gate (both need to be pressed, and when they are both LED strips light up) idea is if I touch bottom sensor the bottom LED lights up, and if i touch top sensor only the top strip lights. Jumpers are in Jog low output (only A jumper is welded), ignore black wire that's for increasing sensitivity.

I have tested without microcontroller and it works as it's supposed to do. Question is now which resistor to put and where exactly on data line (D4 pin). I have read somewhere that it need to be 220 ohm pulldown resistor but to be honest that does not mean to me much

Hello,

You can not drive the ledstrip directly from the TTP223 module.
The module can only drive 8 mA.
The ledstrip will likely need much more current.
You will need a driver between the TTP223 module and the ledstrip.

I know that i tested and it drives the strip perfectly (i only need it for a few seconds and each strip only contains 5 led's) I will add logic level FET transistor later and some capacitors when I come to stage of designing pcb but this problem will still persist where the ttp's will work like and gate when connected to esp

here is the link to youtube video it may be easier to demonstrate
