Mini weather station
I know it's been 7 months since your post but I was wondering if you tried adjusting the LCD contrast?
Thanks a lot indigod0g for your project. I've some problems with my weather station, I only receive something like that (see attached image). Any Idea? thanks in advance.
I had the project working, "Everything was working" then I noticed that the degrees were in Celsius, so I thought I would change the degrees to Fahrenheit, well when I did that, I did not get any readings, so I changed the code back to Celsius, well that did not change anything back to where it was and I still got no readings, just a blacken in squares on the display of the LCD. I felt stupid and wondering why I did it in the first place and it was curiosity of course.Even changing out the DHT11 did not change anything, so now I am not sure what it could be?
I was wondering if there is anything that needs to changed with any of both codes for either of the arduino boards?
Hi,from what I can tell in the photo, you have connected the DHT11 on digital pin 11, this should be on digital pin 4.I really am sorry for this, as I have not corrected the Fritzing file to match the instructions, please connect the wiring according to the text, the photos and the code, NOT the fritzing sketch.[this is noted, I will correct them ASAP, I'm just swamped right now)Please do the following:- double check your wiring, as some cables are hard to see in the photo, again: connect the wiring according to the text, the photos and the code, NOT the fritzing sketch.- first on the transmitter arduino: see what data come to your serial monitor via the serial port. See that the DHT11 does give you readings. If not, check it's wiring.- then on the receiver arduino: see what data the serial monitor shows on this side. If the data are 0, check both the RF433 wiring and make sure your antenna is the correct length.Lastly, I thought that by saying "stay plugged in" you meant on the computer in order for the code to run. The boards MUST be plugged in some kind of power source to work, either that is a USB or a power adapter (see the arduino page for the board you are using to see what voltage input it can take).I hope this helps, please feel free to ask anything you might have a problem with, just have in mind that for the next week or so, I will have no easy internet access, but I will get back to you as soon as I can!
I have a problem with my project. I entered the codes into the boards and there is no reading on the LCD display ( Temp: 0C and Humi: 0% ). Temp in the room is 72 degrees.I also remember you telling me that once I have entered the codes into the boards that the project could power itself without being plugged in and that is not happening as well, it seems like it needs to be plugged in to my laptop.
Hi!Once you've flashed (programmed) the boards, the code stays in the microcontroller. So you can unplug it and power it up whenever you need. That causes the code to restart as if you just uploaded it!Hope it helps
Do both Arduino boards have to stay plugged in, as shown in some of the pictures, after putting in the programming? Or can the project run on its own once you have put the programs into the boards?
