Are you going to tell us what the problem is ?
The problem is that when ever I connect the r301t correctly to the esp8266 it does not respond in serial monitor, while if I connect the TX and RX pins wrongly it responds that "Did not find fingerprint sensor"
if (finger.verifyPassword()) {
Serial.println("Found fingerprint sensor!");
}
The logic and/or messages here look wrong. From the name of the function, verifyPassword() should try to verify a fingerprint, the outcome of which will be either that it is verified or not but instead it reports whether a fingerprint sensor was found or not
The else clause is even odder because it reports that it did not find a sensor, says that it is waiting for a valid finger then goes into an endless loop from which it cannot escape
Please how do i do this
Are there any examples with the library ?
i dont know i got this from a youtube video
Do you have the Adafruit_Fingerprint library installed ?
yes
Then there are examples of its use in the IDE
Look in File->Examples
ok i should try right
The solution to my problem was that I had to use another pin instead of the rx and tx pins this is the edited code :
#include <Adafruit_Fingerprint.h>
#include <HardwareSerial.h>
const char* NAME; // the name will be gievn in the code for each ID saved
const char* ID; // the ID that are save into the fingerprint sensor
String Event_Name = "fingerprints"; // this is the name of the file of the database
String Key = "6yg6iEi1eDqCsPGHBRx0N2OnDLT4HPDVygsJ7lsxFU"; // this is my unique key for the database created
// Replace with your unique IFTTT URL resource
String resource = "/trigger/" + Event_Name + "/with/key/" + Key;
// Maker Webhooks IFTTT
const char* server = "maker.ifttt.com"; // here database is store
// Replace with your SSID and Password
char* ssid = "Home Solate"; //wifi name
char* pass = "bread2009a"; // wifi password
SoftwareSerial mySerial(14, 12); //14 for D5
//12 for D6
