I installed Arduino Uno with paj7620u2 as shown in the picture.

I tested with the following code and the result is initialization failed.

#include "RevEng_PAJ7620.h"

RevEng_PAJ7620 sensor = RevEng_PAJ7620();

void setup() {
  Serial.begin(9600);
  if (!sensor.begin()) {
    Serial.print("PAJ7620U2 initialization failed");
  }
}

void loop() {
  Gesture gesture = sensor.readGesture();

  switch (gesture) {
    case GES_FORWARD:
      Serial.println("FORWARD");
      break;
    case GES_BACKWARD:
      Serial.println("BACKWARD");
      break;
    case GES_LEFT:
      Serial.println("LEFT");
      break;
    case GES_RIGHT:
      Serial.println("RIGHT");
      break;
    case GES_UP:
      Serial.println("UP");
      break;
    case GES_DOWN:
      Serial.println("DOWN");
      break;
    case GES_CLOCKWISE:
      Serial.println("CLOCKWISE");
      break;
    case GES_ANTICLOCKWISE:
      Serial.println("ANTICLOCKWISE");
      break;
    case GES_WAVE:
      Serial.println("WAVE");
      break;
  }
}

I would like to check if my I2C is working properly, I tested an SSD1306 OLED Screen and the result is that it can display pictures and text properly.

#include <Wire.h>
void setup() {
  Serial.begin(9600);
  Wire.begin();

  Serial.println("I2C Scanner...");
  for (byte address = 1; address < 127; address++) {
    Wire.beginTransmission(address);
    if (Wire.endTransmission() == 0) {
      Serial.print("I2C device found at address 0x");
      Serial.println(address, HEX);
    }
  }
}

void loop() {
  // put your main code here, to run repeatedly:
}

I’ve tried three brand new paj7620u2’s and none of them are detected, I’m wondering if I’m making some kind of mistake and not finding them.
