Sometimes technology can make you really want to bang your head against the proverbial brick wall. I’m definitely feeling that today as I spent quite a bit of time attempting to get two Xbee modules to communicate. Here is my setup. I have one Xbee controller plugged into my Make Controller and another plugged into [...]

I just received an inexpensive keypad from SparkFun the other day and have attempted to hook it up with no such luck yet. I’m hoping I am just being stupid about the whole thing. I grabbed the Keypad Library from the Arduino Playground and set the correct pins according to the Arduino tutorial. No such [...]

I always love receiving the next device I plan to experiment with. Its so exciting opening up the packages! Its like Christmas or something.
Anyway, enough of that. I got two Xbee modules in this week. I decided to go with the regular Xbee modules because I’m just playing for now. I’m sure I’ll order the [...]

Well, the new LCD4×40Bit-ShiftReg library is working quite well. I’m actually thinking about changing the actual name of the library but figure the above is too long. Maybe I should try something like LCD3Wire4×40 or something. Your thought are greatly appreciated!
So anyway, I added my Parallax RFID card to the setup and finally worked out [...]

Well I have finally finished the update to the original LCD4Bit library I have been hacking to bits. I’ve changed the code so that it now supports the 4×40 LCD with a NXP 74HC595N shift register. I had a hell of a time getting it all to work together and ended up having to setup [...]

Well, I just got the Make Controller in the mail this week and am excited to start playing. I managed to get it hooked up correctly after I flashed the controller with new firmware (did not work out of the box). I’ve also been working on interfacing it via OCD with C#. I can’t wait [...]

So I got a reply from John Ryan on the Arduino forums and he mentioned that I would need to use an interrupt to grab RFID data to ensure it did not stop my program while waiting for a tag. I banged my head around with the implementation of interrupt code but found a solution [...]

So I managed to grab a Purdy LCD sample (thanks to LadyAda’s page) to test Arduino interfacing. The first problem I ran into was that my LCD has two LCD controllers (KS0066 - based on HD44780). Thankfully lega7 faced this issue and modified code to work with a 4 line LCD.
I started with that [...]

So I’ve been playing around with the Arduino now for a month or two and trying to interface it with a few of the Parallax accessories I have lying around. I’ve been meaning to post stuff here the whole time but was lazy. Anyway, here is some modified Wiring code for Arduino to use the [...]
