R305 Fingerprint is not responded with ESP8266
Posted: Sun Mar 18, 2018 11:43 pmR305 fingerprint is not working with ESP8266. I have using Ardunio IDE and include adafruit fingerprint sensor library too. But Fingerprint is not responded.
Note: R305 fingerprint operator on 5V and ESP8266 not support 5V. For that I have used 3.3v and 5v breadboard power supply module.
Finger Print module consist of four wire:
1st wire is connected - 5v
2nd wire is connected - GND
3rd wire is connected - RX
4th wire is connected - TX
In adafruit fingerprint sensor library enroll.ino file they mentioned that SoftwareSerial mySerial(2, 3); 2 and 3 denote which pin I have to connect in ESP8266.
Please any one can help me on this.
Thanks,
