Codes

#include "TTP229L_I2C.h"

void setup() {
  Serial.begin(9600);
} 

void loop() {
  unsigned int dat;
  dat=TTP229_i2c_read();
  Serial.println(dat);
  delay(1000);
}

Result

After uploading the code to the UNO board, connect the UNO board to TTP229L module. Powered up, you can see the red LED on the module is on, then open the serial monitor, touch the key with finger and you can see the corresponding value as the figure shown below:
