Hi Bill,

I'm glad you put this forum site up.  Perhaps I can meet some interesting people that share the same interest I have.

I'm a longtime systems/applications developer that started out in the electrical engineering field and end up in the computer programming world.  The past 40 years of my career have been involved in such system design and architecture.  However, I have dabbled in the electronics analog and digital side on and off over the years just to keep things interesting.  I have followed many of the Videos by Dronebot Workshop. (even done quite a few of them) and found them very relaxing and satisfying.  LOL I've geeked out my family so much that the won't talk to me anymore other than the usual family chatter.  😀 

I really enjoying working with folks who just want to experiment and learn the various technologies.  Recently I've re-built my own lab here at home and have been playing with SMD soldering techniques on various projects.  I've been doing what I can to support the STEM concept with my nephews, and grand kids.  At least they were interested in doing a lot of THT kits that we found on Amazon.  

A couple of other projects I've built involved building a 555 timer and Op Amp from discreet components just so I can poke around them in practical applications.  

Also, Ben Eater has quite a few great videos on computer designs that I have been following along with Dronebot Workshop.  

I like your approach to demonstrating and experimenting with infinitesimal number of topics.  I can't even remember when I started with Arduino or when I first came across it.

I'm based here in Denver Colorado, where the weather is always changing....

Anyhoo enough rambling.

Any topic electronics and hardware design is of interest to me.  I just too passionate to stay with one thing.

David of Denver

Welcome to the forum David.

You'll find a lot of dual background folks here who'll be happy to supply you with all the discussion, help and ideas you can handle 🙂

Experience is what you get when you don't get what you want.

Welcome David of Denver,

Such eclectic interests! You will undoubtedly find the forum of great interest and a source of help.

Looking forward to reading about your projects here on the forum.

Thanks for the warm welcome.

I am currently experimenting with Arduino on:
1.  Audio Level Meter - Trigger an event on exceeding a certain decibel level.
2.  Programmable Macro Key Pad to automate redundant tasks.
3.  Playing around with the SPI interface and protocols to communicate with an old 6502 microprocessor set up..
4.  Liquid Level Low Alarm.
5.  Shift Registers
6.  Addressable RGB LED Strips

I've just recently moved over to Visual Code as My Arduino IDE (Not using Platform IO).

Playing with other different sensors, (Accelerometers,  Voltage / Current detectors.)

So, yes, I'm exploring quite a bit

@mrremedy Welcome aboard.

I am a full time RVer so  Liquid Level Low Alarm's are of great interest to me. My add-on package is not working for the black tank.

I am hooking up some addressable RGB's today for our Christmas lighting.

@ronbentley1 Yes, I have a smart watch that basically shocks me to remind me.   LOL

Belated welcome to the Dronebot forums. The Ben Eater stuff was something I was doing many decades ago! My first CPU was built out of relays. Although it was a wonderful ride I wouldn't want to go back there again. I suspect a lot of high level professional programmers don't really know how the magic is done at the hardware level.

@robotbuilder Careful, I started out at IBM hardware school that included the ROS (Read Only Storage) programming, machine language and assembler. Later I learned fortran, PL1, Pascal, C, smattering of Cobol, RPG, and many more that I don't remember. The hardware in those days was discrete transistor so the similarity between a relay version of an AND and a transistor version was virtually identical. Today most of that background is not much help. The average program today is 90% library code. The IBM tab family of machines was programmed by plugboard and was all relay. There are still a few of us old folks around.

I did make the point about using the Arduino C++ IDE is not really programming at the lowest level even with something as simple as the i/o to the pins but I deleted it to shorten the previous post 🙂

Yes today programming is very high level.  Maybe one day we will simply type (or speak) a human language description of what we want and then a computer program will translate it into the code required to produce the desired behaviour.

@robotbuilder Like totally agree.  I've always believed paying attention to the basics gives a better understanding of the higher levels of things.  In my work, application designer just don't cut anymore.  If they come across a glitch, they find the error in their log then throw it over the fence to the network/database/server OS guys.  Then it's take 4 times as long to troubleshoot and fix problems.  There's an issue right now where I'm seeing bizarre networking communication issues with two systems, the application and networking guys have been pulled in but they're scratch there heads and want to escalate it higher.
The hardware aspect has been a tremendous feather in my hat for troubleshooting various network devices.  Just know you can't drive a 100 amp POE device with a 2 amp POE switch is never considered in troubleshooting circles.  🙂

@robotbuilder I'll bet that relay computer was a bit noisy.  (Clickity Clack!!).

I restored a couple of old pin ball machines that relied heavily on relay systems.  The shooting galleries were my gig.  I took a few built in the 50s and interfaced digital numeric score boards to them.  A lot of debouncing circuits, but it worked.   Got an A in the course.  LOL
