#96199 Please help me write a code for esp8266 access control using a 16x2 lcd display and a membrane keyboard with the function of resetting the code to (*) and re-entering the password and confirming to (#) so that a 4-digit code is entered with the output whether access is allowed or not on the web interface. I've been struggling for a week and nothing works.
