There are some other good videos with success and code. What have you tried? For instance you can connect RYLR devices to you computer. Using a dumb t...

@gtmize try this one from Bill:

Yes indeed. Back in myyyy day (spoken in old geezerese), I built The Micro TO Keyer. This can still be found on the internet and was originally publis...

You don't need the adafruit board but two like Reyax will work together. In the former case both need to be capable of working on the same band, ie, t...

Welcome to the Forum Eddy. I too am retired and awakening old avocation from the 80's myself. What cool toys these youngsters have eh? We had some mic...

So it's been 30 years since I wrote any code and even then not much before my career path took me away. I ended up heading up our electronics hardware...

Both ways if coding work. The code is fine. Never was broke. I was toggling the wrong input pin low and high on the Nano. I'd post a video but 10mb li...

Later I'll define the digitalRead variables as boolean.

It does just that. My original code was in excess of what I needed so this suggestion was to simplify it to what is really required. I was trying to d...

I found the problem. digitalRead does not read a pin number rather it reads the function of that pin. In other words pin 10 is D7 on the Nano. Pin 13 ...

Pin 10 if pulled low should result in the serial monitor displaying 0. It's nor doing that.

I have been trying to figure out why this code fails on a Nano. Regardless of pin 10's state, the monitor reports a 1. What am I doing wrong?? c...

Hi Alan. I'm no pro but I found a library with good documentation. I'll post when I get home. I believe it runs with Adafruit GFX. Also there are si...

@gee post it. You got me curious about the ham radio area here. I'm new at this, been 40 years since I wrote code

I got this from the Arduino site. This is a lengthy discussion on the problem. I still don't understand it but I can see where I would like to parse a...
