All the technical details (and more awesome pi projects!):

RFID Check-In on a Raspberry Pi

Hey guys! What’s going on my name is Matt and today I’m not doing a museum update and I’m not doing a 3d house model those
are two other projects that are crazy and I’ve been doing other stuff and so…

This video is for one of the projects that fell through the cracks if I don’t
make a video about it no one will ever know that I did it so let’s do it!

So a while back somebody came to me and asked me to do a project for a small like a kids ministry thing at church and they needed a way to get kids checked in and have like an account for each kid on this app, right… And so they needed to play games on the app and they you know keep they earn points and all this kind of stuff to kind of keep track of all of everybody’s stuff. So the first phase of creating this app I thought will they have these bracelets that have RFID tags on them and so if you could use that to track the kids and keep track of how many points they have each. That might be a good starting point so I created an RFID chicken system as a prototype for the app that never happened so here you go:

Alright guys, so the very first thing that I grabbed was a Raspberry Pi and an RFID reader writer module so I can read the the actual tags themselves. So once I got those things together, I started to work on the wiring of the RFID module to the Raspberry Pi itself. And so that was put together with a breadboard and if you guys want some more information on exactly how that’s all rigged up there’s a link and in the description. And so once I had all the wires run from the RFID module to the Raspberry Pi it was time to boot up. And so once I booted up I was able to create two Python files and save them in a special RFID directory inside of the Raspberry Pi.

So the first one is called read and it does just what you might expect it to it will read the identification number on the RFID tag and so every single tag that is created has an ID number and so the read function inside of the script will print out that number and any other information that’s written to that particular tag if nothing else is written it will just print the ID so
that is the script for reading the tags and then there’s a second script that is
write PI and it does the same exact thing except for your writing additional
information to the tag so in order for the scripts to function you need to
execute them so first off I’ll just execute the read function so once you
execute it it’s going to enter a like a listening mode so when it detects an
RFID tag that has been tapped to the sensor it will say okay I see the tag
and here’s the ID number any other additional information written to that
tag and in order to write to the tag you just execute the right program and then it’ll ask you to enter a little bit of text or whatever information that you want to associate with that particular tag so for my example I just put a string of text that says it is written and then once I wrote that to the tag I
was able to read that information back and output that to the terminal.

Alright guys thanks for hanging out if you want to know more about this RFID reader writer I have some more information and technical details and wiring diagrams and all that good stuff in the link below and hope you guys enjoyed this one we’re gonna be neck we’re gonna be back next time probably on home design 3d animation need things but I’d like to
get back on the museum train that’d be great so we’ll see how it goes
and I’ll see you guys next week peace out!
