Because my goals are very simple – send data from one nRF24L01 to the other – I hooked the boards up to my Mac’s USB ports.
I wanted to watch the sends from one RF and the receives to the other RF in two separate windows on my monitor. Unfortunately, the Arduino IDE is restricted to showing output from one serial port at a time….
…I wanted two serial monitors – one for each Arduino so that I could follow the debug Serial() statements I put into the sketches. But how? Clearly I could put a separate LCD on one. However, it would be easiest to have two windows on my display.
I asked how I might do this on the Arduino subreddit. Another YIPPEE! moment. I found skootle’s response particularly helpful.
I wanted to automate opening and closing the two serial outputs….
