Hello, I am new to Flowcode and programming in general. I am doing a project in College on RFID systems, I need to make a system that will provide ID-based entry into a room and trigger the activation of a lighting scheme. This system will use an RFID reader (with 125khz RFID Transponders) to communicate with a microcontroller (PIC 18F4520) that will release an electric door strike for access and turn on a set of lights corresponding to how efficient the lighting already is within the room. (Use of an LDR) A motion detector shall then turn off the lights as nobody has been detected in the room within a period of time. The complete project will include an RFID reader, a computer, a microcontroller, electric door strikes, relays, light sensors, and motion sensors, along with necessary cabling.
I purchased the following to play about with and to gain some sort of insight into RFID systems.. Im hoping i can use it in my project also..

I am not asking anyone to do my project for me, I just want to be pointed in the right direction as to where i could get tutorials etc
And maybe a little help along the way would be grateful as its a learning curve for myself and will gain from it.
I am also using Flowcode V4.
Im not sure if i posted this in the right place.. Apologies.

Re: RFID Project
I'm not familiar with that hardware, so I can't really help with that aspect. I don't even know if the RFID component in Flowcode is compatible with it.
We do have a number of resources and examples on RFID. You could try searching on our Learning Centre for "rfid".

Hello K-gallery.
Most of the 125KHz readers use Wiegand 26 protocol to output rf-id card or tag data.
To handle these data using a microcontroller you have to use
3 wire (GND, DATA0, DATA1):
0's are impulses on DATA0 line
1's are impulses on DATA1 line
data bits are prefixed and postfixed with parity
length of data bits chunk can vary from 24-40 bits.
Some more information about you can read bellow:
