Hello sir, I saw a video on RUclips, the video was about a biometric attendance system using a fingerprint scanner and NodeMCU with a database & 3D printed casing. I want to ask whether this connects automatically with USB and PC, because if you use it with another power supply, the nodeMCU doesn't sync with the website.
how to combine both enroll and fingerprint codes together ? so when a finger is not registred , it should register it and if it's already registred it should print its id , how to do that without any buttons
Sir I have some problem in that code, http.begin(link); Compiler shows the error that is 'HTTPClient : : begin' declared with attribute error : absolute API, use : : begin(WIFiClient, URL). Pls help sir I got the solution i.e Reduce ESP8266 version to 2.4.2
HELP ME....!!!! I'm facing a very annoying issue here.... whenever I'm trying to enroll a fingerprint through database (e.g 7:39 in the video) , my fingerprint sensor is supposed to blink continuously for scanning a fingerprint as we see in the video... BUT, my fingerprint sensor is not responding correctly at all.. rather it blinks about 11s periodically... (I've checked fingerprint enrollment in the arduino example code...In that code the sensor works fine... it blinks continuously for scanning...But in this code the sensor is not blinking as it should be....)
How can I edit the visual look of the website? Means I edited the header.css, users.css, managelog.css and changed the color, font etc but when I relaunched the website it didn't change
