Important Note: that you can not have 2 serial connections opened at the same time. Configure it to see the Arduino serial commands This step could be done better writting directly a customized python script… but if we want a quick and useful solution, this should be enough!! RealTermĢ. RealTerm is a Serial/TCP Terminal, similar to Putty (in Windows), but with extended options. There are other programs that allow you to do this, but I found this one “easier”. To save the data coming from the COM port into a CSV file (comma separated value), I used the software realTerm. For Shows or DemosĪlso, this makes a great feature to present or show your project to others.ġ- Write the data from Arduino Serial COM Port into a CSV File Many of us only use single delays and Serial.println( ) to figure out what is happening on the board. How many hours of my life I spent starring at this serial monitor window with encrypted data!!! Arduino Serial Monito Arduino Code-Debugging If you arrived to here, I think I don’t have to convince you that debugging with the serial monitor… is not nice, right? Simply & fast: Because the serial monitor of Arduino is a *shit*. Why Plot real-time data from Arduino’s Serial Port? This avoids the need for writing a custom script, which is time-consuming, especially if you never did one.Ĭould be the smarter solution to work with sensors.
In this tutorial, I am going to explain one simple solution with free software like RealTerm and KST.
Plot a processed signal from Arduino COM Port in real-time is a useful practise when working with sensors, especially for debugging and developing.
