Arduino Serial Read Text Files
I have a text file that is stored on my Yun's sd card that contains weather data that is being updated every 15 minutes or so by a python script. I have formatted the text file to look something like this:
Sparkfun Arduino Serial Read
data1 = 68.8
data2 = 25.4

Any kind of data can send through this serial monitor. To read incoming data in Arduino 'Serial.reads ()' And 'Serial. ReadString ()' are two very useful functions. This to function reads the data which are come to Arduino serial port. Serial communication, (read, write from/to. Learn more about arduino, serial MATLAB. Toggle Main Navigation. I would be able to read whatever the arduino print in its Serial Monitor but I won't be able to manipulate the i/o pins directly (I could to sent a command through the serial and then have the arduino do something when it receives.
data3 = Sunny
data4 = 1.0
And so on.
There are a total of maybe 15 discrete variables that are identified on the left side of the equals sign and their updated values are on the right side. Each unique variable is on its own line and that's all that's in the file.
So... how can I read the variables into my sketch and be able to then call them out from within the sketch? i.e. Serial.println(data1)
Am I going about this the wrong way by creating a text file as the middle man?
I've searched high and low and I can't seem to come up with a proper example that mimics what I'm trying to do, so thanks for any help you can provide!
