Hello everyone! I'm new on this forum, I have been employing arduino boards on my automation projects both at school and at work for while now.
I have a question, how can mutual communication between excel and arduino be posibble?
I want to be capable of reading a RFID card ID and then send it to arduino, save it inside a variable and then compare this code (whis is frequently composed of 6 digits) with a database in an excel data sheet which will have a list of allowed card id's, and then if the RFID card read value matches any of the codes stored in the excel datasheet a digital output will be activated.
is it possible to do this?
if so, can you please give a general idea of how it would be please...
