Actual Component List;

• LM335AZ: IC, Temp Sensor, Precision, T092
• 2x A000021: Board, Arduino, XBEE Shield, w/o module
• 2x XB24-BWIT-004 module, ZIGBEE XBEE ZNET 2.5
• 2x Arduino UNO
• 2x 1k ohm
• Personal Laptop
• A-B USB Cable

Software Used;

• Arduino Software (www.arduino.cc/en/Main/Software)

For today, we managed to update the Arduino driver and tested the module with the 'Blink Code' already preset into one of the files. With the use of the built in LED on the Arduino UNO, the test was to show that the codes could be compiled into the device. For the first few minutes, all that happened when we tried to upload the codes was,

avrdude: stk500_getsync(): not in sync: resp=0x00

avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

Searching the web for solutions to the problem, it turns out all we had to do was disconnect and connect back the cable.

Next, we added the LM335AZ to the circuit. Followed the Basic Temperature sensor diagram on the LM335AZ datasheet. On the Arduino software, what needed to be shown was the temperature taken from the LM335AZ which could be in Celsius, Kelvin or Fahrenheit. Future updates soon.
