Step 11: Install the RFID Reader

In this step, we will install the RFID reader on the upper platform.  For this step, the following parts and tools are required:
  • Serial RFID card reader (Parallax part number 28140)
  • Four #6-32 x 1/2" Round head machine Screws
  • Eight #6-32 Nuts
  • Four 12" Male-Female Jumper wires (Sparkfun part PRT-09385).  You'll need a red, black, yellow, and green.
  • Screwdriver
  • Small pliers
Follow these steps:
  1. Place each of the machine screws in the holes on the top of the upper platform and secure with nuts as shown in the second photo. Use the screwdriver and pliers to ensure the screws and nuts are tight but do not over-tighten.
  2. Place the RFID card reader onto the screws as shown in the third photo.  Make sure to place it so the components on the card are facing down: that way you will be able to see the the "enable" LED on the reader change from red to green and back as the gizmo is working.
  3. Secure the RFID card reader with the remaining four nuts as shown in the fourth photo.  Use the pliers to tighten the nut but don't over-tighten.  The RFID card reader and upper platform will look like the fifth and sixth photos.
  4. Slide the female ends of the jumpers onto the pins on the RFID card reader.  It is very important to follow the color coding - if you don't, at best the reader won't work, at worst you will damage or destroy it.  See the last photo.
  • Red - VCC (positive)
  • Yellow - Enable
  • Green - SOUT (serial output)
  • Black - GND (ground)
<p>hi bruce, im new here at instructables and hoping you can help me out, im a beginner at programing so i dont know much about the python, i was wondering if i can change the command that the rfid is doing, meaning, instead of opening a web i will instruct it to play different video located locally at my pc, hope you can help me with this one, thanks x </p>
<p>Hi Jorette. It's definitely possible. I'll do a little research and then reply with some instructions on how to do it.</p>
<p>I love the combination of Python and the Arduino. So I have created a collection about it. I have added your instructable, you can see the collection at: &gt;&gt; <a href="https://www.instructables.com/id/Arduino-and-Python-and-perhaps-a-Rasberry-Pi/"> https://www.instructables.com/id/Arduino-and-Pytho...</a></p>
I b lov'n your project! Nice ible!
This is so cool! And I love that it exists mostly to be a fun gizmo - just for the joy of it. Voted for it!
Nice artistic flare <br>
Wow, fantastic project Bruce. You put a lot of details into the steps, which is great. The box is a thing of beauty!
Thanks! I had a lot of fun with this one. I was surprised how long it took to document it compared to making it! :-)
This is pretty awesome, voting for you!
