I teach at our local library about Arduino programming and light electronic usage. Have kids from pre-teens to their 80's. :) We did a simple weather station... two sensor modules and about 2 minutes of breadboard wiring and a little code and they had a weather station with 24 to 48 hour predictive...

First sorry for the late response I have been ill for a while... Interesting!!! I retired to a quiet mountain location, but the concepts do remind me of my former profession. Is 8 Hz a choice or a limitation? It is a DIN/ISO regulation requirement. Sound pressure levels have to be processed a that p...

Hi I have a program that issues at midnight the summary of the past day. It should issue the summary in a line appended to a file. That file should be in the csv format, for post processing in Excel. All is done now. But I would like to begin the line with a date identifier. Only day/month. And that...

As an example of power of an ESP8266... early-on in the Covid, I thought I could help with the staggering demand of ventilators - https://inqonthat.com/inqvent/ . If I recall correctly, the little ESP8266 was able to handle reading two pressure sensors, while controlling two servos and a PWM motor ...

Hi for my project https://github.com/rin67630/Victron_VE_on_Steroids/ I have coded an UDP transmission between modules that works pretty well: The information is grouped in a single structure payload[] struct payload { //***Operating Values from Victron/SmartShunt*** float BatV; // V Battery voltag...

Very nice !
I will give it a try after the season holidays.
Have you got a version for the ESP32 too?

Well, in my case, I use the RX pin as a third GPIO (the ESP-1 is a very small breakout). Point is, I can still use TX pin to transmit serial at the same time That is the opposite. I just would want to liberate the TX pin that is not used and pulled up with 470 Ω, which draws quite a respectable qua...

What have you done with your ESP8266s that you consider being a lot of code?

Personally I am working on
https://github.com/rin67630/Victron_VE_on_Steroids
and it compiles at less than 50% resources.

I would expect it works on the ESP8266 chip, regardless of breakout board... As far as I know, it's the same chip on all the 8266 breakouts? Did you try it on the ESP-12? Would be interesting to hear if it works. I could try it on an Adafruit Huzzah 8266. That appears to liberate the TX pin for use...
