Visualize data from sensors using Arduino + coolterm
Here’s how in only a few steps!
I made this particular Instructables using a sonar sensor (XL Max Sonar EZ/AE) but you can do it with any data values that are separated in arduino by a carriage return and a line break:
To put it simply, the incoming sensor data should look like this in the Arduino Serial Monitor:
Separated by a newLine.
Step 1: Get CoolTerm
Download it at : http://www.macupdate.com/app/mac/31352/coolterm.
Step 2: CoolTerm and the Arduino code
Serial.println(potValue); //print the sensor value to the debugger panel
Any code for one sensor would work, for instance the attached circuit and code would work for a photocell to measure light levels.
Instead of the photocell I’m using the Max Sonar Sensor to measure proximity.
Step 3: Connecting to the Serial Port in CoolTerm
Make sure the Baud Rate is set to 9600 (because remember in Arduino, we set it to 9600 using Serial.begin(9600);
NOTE: You cannot have two Serial ports open at the same time, so you cannot view the arduino serial monitor while you are using CoolTerm.
Step 4: Start Recording & Saving
You should see data scrolling through in the serial monitor.
Begin to record the data:
Click Connection –> Capture to Text File –> Start
You can specify where to save the text file.
