I connected up the rfid reader last night, and installed the libraries. But no joy. LED was flickering on the reader, but nothing getting through to the raspberry pi, so possibly my slapdash soldering. I've resoldered it all today at work and am trying again, though here the raspberry pi is trickier as I don't have a usb keboard or hdmi monitor, so we thought we'd try it out on the arduino. Tried two different arduinos, but nothing being read by the device. So maybe the hardware is faulty (is faulty now following my soldering).
Have rewired it for the raspberry pi now and will try and find a monitor and keyboard, might wait until I get home.
Steps so far:
+Wire up according to the diagram here1, which I found by reading this one2 though that is far from complete and not very useful. This page is the most useful3, possibly based on the previous two.
sudo raspi-config. So do that.sudo apt-get install [python](/wiki/#python)-devI've also installed this app on the phone, which I can use to read rfid cards, just as a test. The source code for that is here5, though it's all java so not for me.
I have successfully deployed to aws s3 automatically today using Travis6, this is good. Travis CI7 (continuous integration) has been automatically running tests on the code I've been writing, as well as linting it (making sure it's written to standards) and making sure the test covers all the code, but now as a final step if all that passes it bundles it up and transfers it to some amazon cloud storage, so we can include it in all our websites. And here it is8, a demo page of it anyway. It means that we can just include the files from that location and know a) it's the latest version b) it's all tested, this is a good thing.
arduino: Microcontroller, hardware prototyping platform, a tiny specialised computer.
raspberry pi: Credit card sized super cheap computer, awesome.
