Hi, im currently new at Arduino Fingerprint but recently i bought AS608. according to the video, i should only use 4 pins and connect it respectively (see picture). the code im using "Example > Enrollment" file that can be obtain once you install adafruit. however the Serial Monitor shows this(2nd pic). now the problem is whatever code im using related to fingerprint, the system is not working. i wonder what could be the problem?. the fingerprint device' light/leds does shine but it cannot be detect by my arduino uno
i follow this video: 1) connect the pins (3v3, gnd, pin 2, pin 3) then upload code in arduino but mine did not work:
Code:
#include <Adafruit_Fingerprint.h>
#if (defined(__AVR__) || defined(ESP8266)) && !defined(__AVR_ATmega2560__)
// For UNO and others without hardware serial, we must use software serial...
// pin #2 is IN from sensor (GREEN wire)
// pin #3 is OUT from arduino (WHITE wire)
// Set up the serial port to use softwareserial..
SoftwareSerial mySerial(2, 3);
#else
// On Leonardo/M0/etc, others with hardware serial, use hardware serial!
// #0 is green wire, #1 is white
#define mySerial Serial1
#endif
Adafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerial);
uint8_t id;
void setup()
{
Serial.begin(9600);
while (!Serial); // For Yun/Leo/Micro/Zero/...
delay(100);
Serial.println("\n\nAdafruit Fingerprint sensor enrollment");
// set the data rate for the sensor serial port
finger.begin(57600);
if (finger.verifyPassword()) {
Serial.println("Found fingerprint sensor!");
} else {
Serial.println("Did not find fingerprint sensor :(");
while (1) { delay(1); }
}
Serial.println(F("Reading sensor parameters"));
finger.getParameters();
