I have not used Hall sensors so far.Maybe if you check the output with a multi-meter first to check if it is 5v or 3.3v. The Arduino "looks" for high (5 volts) in the rain-pin.The code (its old and needs revision) should run if the concerned libraries are present.

Difficult to guess without having a look at the code. I could not duplicate your situation. Can it be a typo some where? Anyway I have send the code to your email.

Hi, the RTClib is available at https://github.com/adafruit/RTClib and with the newer versions you can use the first method mentioned here. https://thestempedia.com/tutorials/arduino-ide-libraries/ I have included screenshots of the steps below. Let me know if you face further problems. Regards

"I would like to input this into . . " - Thank you, thank you. Please go ahead!

Awesome to see your solar powered weather station and thank you for your kind words. Your 0.0119 inches of rain per tip/click is correct. Yet it is different from my 0.0161 inches/click. We are differing by about 26%. This has come from the fact you got 6 tips for 10 ml while I got 4 tips for 9 ml. Not same. So I have to make sure that my 4 tips for 9 ml is correct or not. Sadly, I do not have the rain collector anymore. However all this has pointed that we need to repeat our calibration observations with great great care. One way would be to use more liquid and observe for more bucket tips. Your query has made me a wiser person, thank you.

Watching the project proceed to a completion was a pleasant journey in itself.

Congratulations for creating a well documented project. I hope the few shortcomings will not deter you from thinking and implementing new solutions to problems. Hoping more from you in future. Goodluck.

Simplicity is the best, and you have nailed it.

In fact, my purchased automatic fish feeder got clogged (the outlet) somewhere in-between my three weeks absence. Some tiny fishes went missing from the aquarium by the time I came back.

Der Teil des Codes -if (now.minute () == 0 && first == true) {---- -------- -------- ----}sendet die Ausgabe nur am Ende jeder Minute an den seriellen Monitor. Wir sollten mindestens eine Minute oder länger auf die Ergebnisse warten.

If there are no complication errors, then (just a guess), I hope you set the baud rate in your serial monitor at 9600bps. . .

Loved the sounds! Shall build it one day "for use".

to calumniate, or not to calumniate, is now, the question

First: Sorry for the long, long delay ....... .......Ans 1. The line rtc.begin(DateTime(__DATE__, __TIME__)); in the setup part of the sketch sets the soft-RTC time to the same as that of the PC at the time of compilation. Consequently, if we start the arduino later, it should start with the same time as that at the time of compilation. I did not emphasize this earlier, my mistake. For logging purposes, this would a serious issue, and we would need a hardware based RTC like DS1703, etc. But for calibration purposes this should do (but not right still).Ans 2. For using such a rain gauge and logging rain data, both will do (again do not wrongly assume me to be an expert). EEPROM has limited writes (100,000 times) and of course of finite capacity. But if you plan to use it to monitor rain,…

But if you plan to use it to monitor rain, keeping your PC on "all the time" and nearby a the rain gauge is not a good idea. Specially so, if your rain gauge happen to be remotely located.Lastly, thank you for your first question, it has showed me that I should improve on this code and make a proper rain logger in future.

Hi,I had used my old weather station's spare parts together with DHT22, BMP180 and UVM30A to upload weather data to weather underground via a Ethernet shield. The code is below, but a few things to note first:1. The code was copies from here, there and everywhere, form the internet.2. A soft RTC updated via NTP was used and modified for my time zone (GMT+5.5).3. The code is sloppy & dirty (and very old).4. Calibrating the wind gauge is slightly tricky. At that time I did not have a hand held anemometer and so I had to go around my town with the anemometer outside my car saving data to a micro sdcard and do regression analysis later :)----------------------------------------------------------------------------------------------------------------//**************************************…

Please may I have a link to the 'wireless charging part'. Thank you.

Such Arduino codes are available all over the internet ( and I shall be glad to share mine too).

In fact this project was created as I wanted to repurpose a weather station rain and wind sensors with an Arduino. It worked fine, uploading data after every 15 minutes (to weather underground) untill a hailstorm totalled them.

Two points from my side:1. Thank you for spotting the error. I have corrected it.2. Please accept my apologies too. I cant figure out, or explain, how on earth I put in the strange number "0.394" instead of the 0.0161 which you have suggested.“If you make a mistake and do not correct it, this is called a mistake.”— ConfuciusThank you again.

A needed gift stemmed from a wonderful idea. Congratulations.

The game should be a rite of passage for every graduating astronaut.

Should be included in every astronaut's graduate course.

Much obliged.

Nice design, it will appeal to young people. Great project too. The Respeaker seems to be available only in Kickstarter.

One of my favourites. Thanks for sharing. In our side we use raw mustard oil instead of butter. Give a good sting. Only downside is the lingering smell.
