Bernie says a lot of things that make a lot of sense. Having nominally followed his career since he was the mayor of Burlington Vermont, where I lived, I can say he appears to be consistent in his views and voting record. While politics in today’s world is pretty convoluted, when he did make a …
Tulsi Gabbard left her position in the Democratic Party in 2016 as she could not abide how Bernie Sanders was being “railroaded” by that party. She came out and endorsed him against the wishes of “the party”. While she may not have all the answers, she (so far) appears to be a person of dignity …
when I went to flush and replace the coolant on the westerbeke 30b in my 2001 Gemini 105mc the drain plug was frozen solid. It seems someone had replaced the brass plug with a steel plug which was not coming out. So after consulting the web, the owners manual and the stars, I came up …

This is part of a larger project that uses the esp32 as a tank level sensor for a boat. But of course, it could be used in any situation that uses non-metallic tanks. This code handles up to three slave cards, but it could be extended to more than three. The code that does the …

The ability to speak several languages is an asset, but the ability to keep your mouth shut in any language is priceless. Be decisive. Right or wrong, make a decision. The road is paved with flat squirrels who couldn’t make a decision. Happiness is not having to set the alarm clock. “The starting pay is $40,000. …

Update using a single esp32 capacitive sensor io pin instead of 5 The original design used 5 aluminum tape strips, very complicated to install and also not as reliable as expected. AND this requires the soldering of 4 additional wires on each sensor module. so here is what is happening so far, all current WORKING …

For how it works, see the comments in the code. the serial output is below the code to see the code I used to come up with this see:https://www.upesy.fr/blogs/tutorials/what-are-interrupts-in-esp32-with-examples-for-arduino-codeandhttps://lastminuteengineers.com/handling-esp32-gpio-interrupts-tutorial/ Using esp32, which lets you use attachInterrupt() on every pin, unlike with the Arduino, which depends on the card and only works on some pins. The …

Okay I am very very annoyed. I have been using Raymarine for well over 20 years and probably before that. SeaTalk , SeaTalk2, nmea 0183 to SeaTalk, Mostly been very happy. On my second Axiom but come on, this SeaTalk-ng cable is GARBAGE. It could just be called SeaTalk-G . Yes, I realize the concept …

This is almost too simple to post, but hey, someone may be stumped. I am only including a short code snippet, and it WILL matter where this function appears. At least it does in this case as I am using it to store a Preference value in esp32 flash memory. As it is in “setup()” …

May all sentient beings enjoy happiness and the root of happiness. May they be free from suffering and the root of suffering. May they not be separated from the great happiness devoid of suffering. May they dwell in the great equanimity free from passion, aggression, and prejudice.
Whereas seeing things as they are and facing reality, as it is, is what invokes drala.
How to easily create a function that can be called from anywhere using existing code that already works. Use this approach to clean up your code, make it “readable” as well as easier to edit, maintain and improve. This is done in the visual micro IDE, which runs on top of visual studio. Both apps …

this is the slave code , master code is on another page
page one of this project Progress, but not there yet. Currently, it does the following. This is the master code, the slave code is separate. Queries up to three slave/sensor/sender units display the tank level readings on one set of 5 LEDs. A second set of 3 LEDs tells which tank is being read; 1, …

This project has way more to do with hardware than the code, obviously. But when looking for an electronic fog horn they were first hard to find, then ridiculously priced. I will get some pictures in here at some point, but it is essentially built from a megaphone similar to the yellow one below, that …
esp32 tank sensor gauge using esp-now on a boat. The project is to create a “touchless” tank level gauge. “Touchless in this case means a sensor does not need ot go inside the tank. While it is for my own boat, the idea is it will be easy to install and use and potentially a …
This works with an ESP32, I have not tested with an Arduino, but it should work. It relies on the WiFi.H Library written by some genius
https://esp32arduino.com/ This may be simple for you, and once upon a time, I probably understood it. But being over 70 years old and coming back to “programming” or “coding” or whatever you young folks call it, it has involved a lot of head scratching. I use this page as a reminder to myself, because by …

Arduino NMEA GPS code to replace paddle wheel transducer uses GPS module TTL to RS232 converter, all code and wiring included.
