Wrapping up what’s happened to the storytelling stickers!
THE READER
The RFID reader is working! It took a while though. I did some search and ended up taking arduino codes from http://blog.formatlos.de/2008/12/08/arduino-id-12/ featuring the AF_SoftSerial library. It’s very well written and comprehensive. The scripts added a kicking off step and a disconnection detection as well. Great work! [...]
I ran into this post today and apparently it’s a similar but much savvier implementation of my unlocking system.
Really like the touch sensor use!
What’s really sad is I was locked again outside my bedroom two weeks ago at midnight. I cannot always stick my arduino to the door.
Nice work Alex!

The transister lab looks fun because I like these DC motors since young. They have a unique smell while spinning really fast. In my impression they could work very well with just 2 AA battery (3V) in a toy car, so I’m curious about how would it be with 9 or 12V.
First I hooked up [...]

I’ve been mostly working on viz class and pcom mid term over the weekend. One big thing is I once made the eight-buck-deal RF Link work in the studio, but never succeeded in testing again since I went back to the dorm. I used software serial library to utilize digital pins as serial input/output and [...]
I do enjoy the force sensor I got in week 5’s application class so I’ll definitely use it more in the assignment!
First I revisited the processing codes I wrote for week 2, which now seems to be a total mess. I didn’t know about the serialEvent callback then so I parsed the serial input in [...]
Lockouts are irritating. especially when you live in a dorm, at midnight, your roommate is sleeping, and backup keys are two hours away.
Here’s the self-service solution.
I should have made a much more complex combination lock with multiple sensors and flexible customization functionalities, but it’s two in the morning… so maybe next time…
Secret revealed. [...]
Hooking up the following stuff according to the diagram was easy and quick. And a resister of 220 10K Om is working ideally to create an ouput range of 0 – 930 (from total darkness to direct shine of torchlight) for the photocell.
I changed the switch from last week to a much smaller one which [...]
I bought my first Arduino boards in 2007 and never touched them again ever since setting up the famous “blinking LED” code sample. It does recall some memory when I have my hands on the chips and boards and wires and stuff… again.
The Arduino I have is an old NG(Nuova Generazione) rev C, which is [...]
