We need to repeat this process of placing the finger on the scanner and releasing two more times and in total three times to add our fingerprint. After that, we need to put our finger on the scanner again and wait till the yellow light blinks and then we can release the scanner.

This shows that the scanner has entered the fingerprint adding mode and as our fingerprint is not already added to the scanner that's why it would show unregistered on the Serial Monitor and assign an ID to the same. Keep finger placed there until the yellow light blinks three times and then release the finger.
Adding a new fingerprint: For this operation, we need to place our finger on the Scanner you will see a blue light blink. We will hover around each of the operations one by one. For that, we first need to open the Serial Monitor which will display messages according to the task performed. So now we will be testing these functions. Those functions are Reading and Testing the Fingerprint, Adding a new fingerprint, and Deleting any added Fingerprint. #Arduino uno pinout black and white code#
The code that we just uploaded had three functions in it. On the Other hand, the Power Supply Pin is there to Power Up the device or turn it ON. When there is a power input at this pin then only the sensor will work otherwise not. The function of the Vcc pin is that it acts as an enabling pin. So here we are using two pins which see to be similar but have different functions these are the Vcc and Power supply pin.
Blue Wire= IRQ Pin(Interrupt Request Pin that is capable of receiving external Interrupts). So we need to take care of it while doing the connections. But one thing to keep in mind is that the color-coding of the wires that comes with this device is different from the normal coding. It is a 6 pin device that can be easily connected to microcontrollers by virtue of the pitch connecter that comes with it. This sensor supports UART communication and while working with the Arduino library, it can easily realize functions like fingerprint registration, fingerprint deletion, etc. Loaded with ID809 high-performance processor and semiconductor fingerprint sensor as the core, the sensor adopts a built-in IDfinger6.0 algorithm, which can complete all fingerprint identification work independently. It supports 360-degree arbitrary angle recognition and deep self-learning function, high performance, and low power consumption. 
The sensor offers fast recognition speed and high security. It comes with round breathing LEDs and has a simple structure, small size, and delicate appearance.
The Capacitive Fingerprint Sensor is a nice and compact one that is similar to the one at the back of your smartphone.
