Arduino CO2 Sensor Controls PCM Fans in HRV

[AC_Hacker]

I was successfully able to run the Teensy "Blink Both" hex examples.

I was also able to make the Arduino "Blink" example run.

I tried different pins, changing code for each different pin, to get the feel of that.

So, I want to be able to get the Teensy to be able to print information out from the Serial Monitor.

I found a dead simple Teensy example on the Teensy site that is called "Tutorial 3: Serial Monitor & Input"

So from that page I cut the code...

void setup()   {                
  Serial.begin(38400);
}

void loop()                     
{
  Serial.println("Hello World");
  delay(1000);
}

...and pasted it into an Arduino sketch.

But compiling and running running the code did not result in my being able to see the Teensy output anything...

So after trying everything I could think of, even burning a candle to the saints (which did calm my nerves), but nothing more. So, out of despiration, I posted a message to the Teensy Forum and quicker than I could say, "this thing will never work", I had an answer...

Turns out that I needed to change a default on the Serial menu...

... and once that was done, the Teensy was more than happy to talk to me.

Road block removed... progress continues.

Best,
