Hi, I'm clearly a complete noob (+old + cranky + not too bright!) and am working my way through using Arduino, so please keep the above in mind.
I'm using quite a number of example sketches using serial connection and serial print to communicate to the IDE serial monitor. When the sketches are compiled and uploaded serial communication begins and everything is wonderful in the world. However if I disconnect the Arduino (ie break the serial connection) and then plug it back in to the USB cable to the host computer there is obviously no serial connection. If I re-upload the sketch, then the serial connection begins again.
I presume there is a send command from the serial monitor function on the Serial Monitor command line to request a connection, but I don't know what it is, and no amount of searching is helping me.
I guess this is a super basic function I don't understand, sorry about that. But after having 2 consecutive faulty RTC modules and wondering what I was doing wrong (nothing as it turned out) I'd like to see if i can get this sorted.
