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,

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

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,

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

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

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

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

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

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

Arduino NMEA GPS code to replace paddle wheel transducer uses GPS module TTL to RS232 converter, all code and wiring included. While it is all in the code, the kind of pseudocode is: Read GPS output at 9600 baud (that is the GPS default) Get rid of everything except $GNVTG sentence Convert

Why an Arduino NMEA0183 GPS to Paddle wheel converter? This project uses an Arduino and a GPS module and a TTL to RS232 converter to read data from the GPS and parse it into a VHW sentence to feed into my existing Garmin GPSMap, so it will feed into my Axiom chart
