Tutorial: How to Use USB Fingerprint Scanner ZK4500

The ZK4500 USB fingerprint scanner is ideal for home or commercial security applications, allowing fingerprint enrollment and identification. Suitable for developers and end-users.

What you need

• PC or Mac with USB
• Arduino IDE
• ZKUHID library
• Fingerprint library

Steps

1. 1. Download and install Arduino IDE.
2. 2. Install the ZKUHID and Fingerprint libraries.
3. 3. Connect the zk4500 scanner to the PC.
4. 4. Check the datasheet for correct power supply.
5. 5. Write basic code to initialize the device.
6. 6. Read the datasheet documentation for specific settings.
7. 7. Try scanning a fingerprint.
8. 8. Verify the scanned data with the device interface.

Example code

```cpp
#include <ZKUHID.h>
#include <Fingerprint.h>

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

void loop() {
  if (Fingerprint.readImage()) {
    Serial.println("Impronta scansionata");
  }
}
```
