How to fix interference from LED strips?

Question

Arduino

Hello to all connoisseurs, as well as to all those who are familiar with physics :)
We have developed a slot machine for our company, the essence of which is that there are two basketball hoops and two infrared sensors under them, which catches the hit, depending on the hit in one of the rings, different information appears on the screen. All this works well, the sensors read perfectly and everything goes like clockwork, but when we connect the LED strips, which should work when they hit one or another ring, the sensors begin to live their own life, that is, they record hits on their own without even throwing the ball and doing nothing at all) The question is why is this happening and how to deal with it? The company that made the slot machine says that it is necessary to install a semi-industrial anti-interference system worth 300k+. I would be very grateful for any versions that can be checked.
Hardware:
- Arduino with an external 5V power supply to which these sensors are connected;
- Raspberry Pi, which receives data from arduino and is responsible for displaying information on the screen;
- Two LED strips (red and green). In case of a correct answer, the green ribbon lights up, and in the case of an incorrect answer, the red ribbon lights up.

Answer 1

First you need to understand what the problem is.
If there is interference in the power supply, then:
1. separate the power supply of the sensory system and the executive one.
2. hang more capacitors in the sensor power supply network.
If the pickup on the sensors is from the tapes, then:
1. check each sensor separately that it is not affected by the light of the tapes (the fact that they shine in the visible spectrum does not mean at all that they cannot shine in the infrared).

Answer 2

Only the tape or the system as a whole lives "its own life"?
If the system counts the hits correctly, but the tape does not work correctly, then we have a banal scam for grandmas. If the calculation is incorrect, then the algorithm of the machine is incorrect. The flash of the tape illuminates the sensors.
In short, you have addressed neither. Alas, this happens.

Answer 3

The tape itself works normally, that is, it only works if the sensors give a command. The problem with the sensors arises when the tape is turned on, they start to work randomly, even if you do not throw the ball and do nothing at all.
As I wrote above, if you turn off the tape completely, then the whole system works with a bang.
