Kit 104 Digital Temperature Controller Arduino Monitor:

  There are instances where it would be helpful to observe the temperature value that is being measured by the Circuit Creations K104 Digital Temperature Controller kit.  By using the serial monitor capability of the Arduino open-source electronics platform we can indeed see the temperature value measurements in real time.  An example of the serial monitor display is shown to the left.


The connections between the Circuit Creations Kit 104 Digital Temperature Controller (after assembly) and Arduino Uno are shown in the illustration below.  Connect the wires between the Circuit Creations Kit 104 and Arduino Uno boards as described in the illustration and table.

 


The program below is written for the Arduino Uno with plenty of comments to explain its purpose and function.  You can copy the code below as a sketch directly into the Arduino development environment and it is ready for compiling and uploading to the Arduino Uno board.  To see the temperature being measured by the Circuit Creations Digital Temperature Controller, start the Serial Monitor from the Arduino IDE and select a 9600 baud rate in the Serial Monitor pop-up window.  Of course, this code can be included as part of a larger project.  Pay attention to comments and pin connections for a straight forward adaptation of the example code to boards other than the Arduino Uno.
