Hello! I bought a nano and a sensor. I connected the sensor to the arduino, (int-D2, vcc-3.3v, gnd-gnd) if I connect scl to A5 and sda to A4, I load gesturetest and open the monitor. It prints out the library name string and the test name and is silent. But if I swap pins, it starts spamming none. Neither in the first nor in the second case does not respond to gestures and any movements. I looked through the phone's camera, the IR is on. What can be wrong?
And how can we know if you don't share your code?
i'm sorry

APDS-9960 RGB and Gesture Sensor

Tests the gesture sensing abilities of the APDS-9960. Configures
APDS-9960 over I2C and waits for gesture events. Calculates the
direction of the swipe (up, down, left, right) and displays it
on a serial console.
To perform a NEAR gesture, hold your hand
far above the sensor and move it close to the sensor (within 2
inches). Hold your hand there for at least 1 second and move it
away.
To perform a FAR gesture, hold your hand within 2 inches of the
sensor for at least 1 second and then move it above (out of
range) of the sensor.
Hardware Connections:
IMPORTANT: The APDS-9960 can only accept 3.3V!
Arduino Pin APDS-9960 Board Function
3.3V VCC Power
GND GND Ground
A4 SDA I2C Data
A5 SCL I2C Clock
2 INT Interrupt
Resources:
Include Wire.h and SparkFun_APDS-9960.h
Development environment specifics:
Written in Arduino 1.0.5
Tested with SparkFun Arduino Pro Mini 3.3V
This code is beerware; if you see me (or any other SparkFun

Welcome! I need your help, I cannot see your setup and how you wired it much less which APDS-9960 Board you are using. Post a link to technical information on the APDS-9960 Board and an annotated schematic showing how your wired it, be sure to include all connections and power sources.
Moved topic to "Sensors" forum category, which seems more appropriate than "LEDs and multiplexing", do you not think @nochnik ?
There is a post at the top of each forum category that describes the purpose of each one. Please read them when choosing a category to post your question.
Did you read any of the documentation for this sensor?
According to the Sparkfun page
https://learn.sparkfun.com/tutorials/apds-9960-rgb-and-gesture-sensor-hookup-guide
IMPORTANT: You must use 3.3V! If you try to use a 5V power supply or 5V I2C communications, you risk damaging the APDS-9960. If you are using a 5V Arduino (e.g. UNO), then you need to have some kind of level shifting.
I am also unsure that the 3.3V pin on Nano will be able to supply sufficient current to the board.
You show a red, blue and purple boards, color is not that important. Missing are the links and the annotated schematic (the language of electronics) showing how you connected it (each time). You can use the tools here to draw the schematic or you can download KiCad or many other free CAD (Computer Aided Design) software packages for free. What does "But if I swap pins, it starts spamming none" telling us. You state: " Neither in the first nor in the second case does not respond to gestures and any movements." What are the other cases and how was it wired for each case.
