hi all so heres a little something i planing on but i want to know how viable the project idea is first the idea is haveing rfid/nfc tags that will play a audio track from a simple tap and show a image on a small ish display
but also beable to have a display and a fue buttons to beable to quickly and easily add new tags and like the new tags to audio files
Welcome to the forum
You mention showing an image on the display. Does each audio track have its own image ?
no some will shame a image
you see this is a little project idea to halp my grandmother out with cooking as she struggles to read so i going to put rfid/nfc tags on each of her food items and the audio track will say what the item is were to cook it and for how long and the image will also display were to cook and howlong to cook in a much larger easyer to read way
What you want to do sounds quite feasible but it may be best to incorporate an SD card reader and to use a PC to edit a text file on it that defines the RFID tag values, associated audio files and images and also to hold the audio files
The Arduino could then read the file either into memory or on the fly when presented with an RFID tag in order to play the audio file
ho i understand i would need a sd card to store files and you think a text file to asosiate a tag with a audio file would be best
It will be much easier to maintain the file on a PC, perhaps as a CSV file, using a spreadsheet to edit it
One line per RFID tag with the tag ID, audio file identifier and image file identifier on each line
The alternative would be buttons on the device to put it into edit mode and for the display to prompt for actions to be taken. At the very least this will be tedious to use, particularly when it comes to entering multiple digit RFID codes, not to mention the work needed to program it
thank you for the help on disideing how best to do some things
Barcodes might be simpler. Definitely a lot cheaper. And for products that already have a UPC barcode, the item name can be looked up having to define it.
but for my intended purpose rfid/nfc tags are more pratical
