Depending upon your version of BBEdit the following should be used as a rough guide.BBEdit->Preferences
Select "Languages" from the list on the left.
Click the '+' under the "Custom Extension Mappings" pane.
Select the "Suffix" side of the new entry and enter extension used by your version the Arduino IDE.
Click on the "Languages" side and select "C++" form the pop-up menu.
You should be good to go!
Thanks but when doing this, instructions like pinMode, Serial.begin etc are not recognised and highlighted. This is very useful to read the code and this is what I am trying to accomplish in BBEdit.
