The project is a beginner guide to interface sensors to Arduino and visualise sensor data through Processing
Project tutorial by sowmith mandadi
The Processing version I used is 3.0 . The arduino serial monitor sends out temperature value in float . TempC is assigned this value by tempC = commPort.read();
TempC is declared as float in Processing . Try printing out TempC values in processing before plotting . Pls comment if you have any issues . Will check out the code once again.
