Xbee Configuration and 커뮤니케이션

2008-10-23T13:59:00.000-07:00

For the communication between two xbees without Arduino, configuration is needed.
So, ATMY, ATDL, ATID, ATDH, ATIA, ATD0, ATD1, ATP0, ATP1 are all configured.
especially, IA command is inevitably needed for output.(It means who is listening)

IA (I/O Input Address) Command
The IA com-
mand is used to bind a module output to a spe-
cific address. Outputs will only change if received
from this address. The IA command can be used
to set/read both 16 and 64-bit addresses.

더 정교하거나 커뮤니케이션을 잘 하기 위해서는 코드 필요.

Dueling Skirt( The final Project of Sociable Objects)

2008-07-02T21:53:00.000-07:00

Garments usually have been used for the way of expressing people's character and their status. However, even though fashion industry makes their own brand images of 'specialty', people still have possibilities can run into the other same outfits. Therefore, as matching these needs and letting people find their own identity, Armanda and I came up the idea as our final project called 'Dueling Skirt'. This project is about people who wear the same clothes never be in the same place.

- System Diagram -
To measure the distance, we use RSSI which is the strength of the signal of XBee.

Dueling Skirt for presentation

Here is my test for pattern changing. This is one of the ways of shift.

About Software Serial

2008-07-02T21:52:00.000-07:00

From the Arduino site:
The Arduino hardware has built-in support for serial communication on pins 0 and 1( which also goes to the computer via the USB connection). The native serial support happens via a piece of hardware(built into the chip) called a UART. This hardware allows the Atmega chip to receive serial communication even while working on other tasks, as long as there room in the 64 byte serial buffer.

Limitations

Only speeds up to 9600 baud work
Serial.available() doesn't work
Serial.read() will wait until data arrives
Only data received while Serial.read() is being called will be received. Data received at other times be lost, since the chip is not "listening".

Rock, Paper, Scissors GAME

2008-07-02T17:45:00.000-07:00

circuit with XBee

Eduardo Lytton and I made Rock, Scissor, and Paper game. The game we made will be triggered by start switch. Once, push the start switch, each side generates a random number for rock, scissor, and paper. It will be sent to the other side as a data and the data will be compared with their own data. Depending on the real rock scissor and paper game, the one who wins the game get the light with 'you win' LED.

'ZTerm' and Arduino code represent procedure when game has started.

Glow LED

2008-05-31T10:31:00.000-07:00

To glow two leds and communicate with two XBee wirelessly, Vikram and I , as a pair, made two circuits with two Arduinos. For circuit, XBee needs 3.3V power. We used the code that Rob posted on the class site. code is HERE.
We used the code and made it works by changing address in the code for each one.

Find & Fix

2008-05-27T05:17:00.000-07:00

As a Find & Fix project, I made an indicator. I found the problem that sometimes there is no water and no person to change an empty bottle of water in the right hall at ITP because all bottles of water are in man's room. Therefore, this is the prototype.
Actually, It is supposed to be drained little by little away but because I couldn't make a water cooler, I will pour some water into a cup to measure how much water left in a bottle.

Led is supposed to be blinked when there is no water in a cup to indicate no water and to encourage to change a bottle.

For more pressure, I put a this kind of shape of wood block on a pressure sensor.

To measure how much water left in a bottle, I used a seven segment. From 4 to 0 the number of sign will be shown.
