Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Using micros() as a source of random numbers
That's why I don't use them for anything fancy

How to drive a ultrasonic transducer and receiver and get wave output
Heh, ultrasonic phase offset can be done with an Arduino's analog comparator (NOT the ADC which is too slow) - here's one I prepared earlier

In your opinion, does a masters in EE or an FE certification hold more weight?
hackaday.com has a zillion links to examples; here's one two three four of mine and I've also got a laundry list of companies I've helped but whose technical details I can't legally publish (note that I've assisted many but not all of the companies in that link)

Can I measure distance in mm size with HCSR04
HC-SR04 can't, but the transducers on it can - here's a proof-of-concept I threw together a while ago to play with them, although you may want a capacitor in series with R6 if you want it to work over longer distances than ~10cm or so

If you're curious here's a couple of my AVR projects (not using Arduino libraries at all), and here's an NRF52 one

Since learning that ChatGPT can write Arduino sketches, it has taken some of the challenge of the hobby away for me, anyone else experiencing this?
ChatGPT often gets stuff wrong and likely can't handle more advanced programming techniques (eg this sort of thing), so it's only going to be useful for basic stuff and shouldn't be used beyond your ability to critically analyze or debug code.

Does this proof of concept where I get absurd precision (at short range) from a couple ultrasonic transducers salvaged from a HC-SR04 and a few resistors count?

Resources for Baremetal Arduino: A curious complete beginner
Here's a random proof-of-concept I threw together a while ago for super precise ultrasonic wind speed measurement (or very short distances) - it uses the analog comparator plugged into timer input compare for phase analysis, which is where the precision comes from.
- Error with " 'Calibration' was not declared in this scope " not working in my code, Can someone help me.

Any ideas on programming this devboard?
I see that the kl05 target was removed in os6 but it is present in os5.

Arduino 32u4 sending 2 separate serials via USB
Most of my interaction with mbed was when it a massive pita since it was still closed source.. I do have one interaction with the project since they opened it though
