Adafruit Fingerprint adalah model fingerprint reader yang lain. Interface Adafruit Fingerprint dengan PIC boleh rujuk PIC Lesson: Adafruit Fingerprint.
Sambungan wayar adalah seperti berikut
- Merah = 5V
- Hitam = GND
- Putih = TX
- Hijau = RX
Berikut adalah demo Adafruit Fingerprint

Ada jual tak fingerprint module yang ini?
Bob, saya tak jual. Boleh beli kat invention-zone.com
salam bro..bole x bro bg procedure untuk vb code ni?
w/salam, abdu hadi. Procedure apa? Sudah diberikan source code diatas.
Salam bro. Macam mana nak save Fingerprint mengikut ID yang kita hendak.
saya ada masalah dengan serial.read sebab apa yang saya nampak ID tu generate hasil dr
id=Serial.read()-‘0’;
id=10*id + Serial.read()-‘0’;
id=10*id + Serial.read()-‘0’;
Saya dah cuba bermacam cara untuk bg input id dr string menjadi integer.
tetap tak menjadi. Harap bro dapat terangkan serba sedikit.
atau mungkin ada cara untuk kita refresh serial.read baru untuk gantikan serial.read yang lama??
w/salam, amin. Kena cuba lagi sehingga berjaya.
Asalamualaikum. saya nk tnye sye guna adafruit fingrprint ni sekali dgn arduino. tapi masa try nk enrol kat serial monitor dia tulis “unknown error”. sye try troubleshoot dpt tahu yg error kat “p=finger.create.Model() ;”mcm mne nk fix prob ni ye. please tlong
ni code nye:
#include
#include
uint8_t id;
uint8_t getFingerprintEnroll();
// Software serial for when you dont have a hardware serial port
// pin #2 is IN from sensor (GREEN wire)
// pin #3 is OUT from arduino (WHITE wire)
// On Leonardo/Micro/Yun, use pins 8 & 9. On Mega, just grab a hardware serialport
SoftwareSerial mySerial(2, 3);
Adafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerial);
// On Leonardo/Micro or others with hardware serial, use those! #0 is green wire, #1 is white
//Adafruit_Fingerprint finger = Adafruit_Fingerprint(&Serial1);
void setup()
{
while (!Serial); // For Yun/Leo/Micro/Zero/…
delay(500);
Serial.begin(9600);
Serial.println(“Adafruit Fingerprint sensor enrollment”);
// set the data rate for the sensor serial port

Waalaikumussalam, saya x tahu.
rasyid beli projek. rasyid budak baik. jadi macam rasyid
Hello sir. May I get VB.NET Source code. I don’t see link to download it above.
