So, I am electronics are my hobby and I am mostly self taught, so I may get a few things wrong. Here's the project: To make Arduino-based modules which are centralized through a single computer. The modules are varied and encompass everything. For the working prototype, I am using only parts salvaged from old electronics, and I am making modules with different functions to illustrate the adaptability of the system. This is a huge project, however, for a security module, I am integrating a magstripe writer using the parts from an MSR X6 I bought. I want to use only the heads from it and the encoder wheel. However I can find no documentation for the heads. I have a good understanding of how they work, however I am just a novice with this kind of stuff.
The writer head has 7 wires, 2 red for one track, 2 blue for another, and two white for another, and one ground. I was hoping to use an L293D for the half-bridge because it's available for the reversing of polarity with a 9volt source for the power.
The encoder wheel however has 3 wires, red, black, and blue. I can find no documentation or guides as how to wire it to the Arduino and how to program it.
There is also a reader head which has red, black, white, blue, and brown(replaced with a second red) which again, no documentation to wire it or code it.
Any direction or suggestions will be helpful. I will post pics later. Thanks
