Ultrasonic-poc Alternatives

ultrasonic-poc reviews and mentions

• Using micros() as a source of random numbers
  2 projects | /r/arduino | 8 Dec 2023

  That's why I don't use them for anything fancy

• How to drive a ultrasonic transducer and receiver and get wave output
  1 project | /r/AskElectronics | 30 Apr 2023

  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?
  3 projects | /r/ElectricalEngineering | 30 Apr 2023

  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
  1 project | /r/arduino | 24 Apr 2023

  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

• Single-supply bandpass filter is clipping

  PS: https://github.com/triffid/ultrasonic-poc may interest you ;)

• Libraries

  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?
  1 project | /r/arduino | 25 Dec 2022

  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
  2 projects | /r/arduino | 27 Jul 2022

  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.
