    Mini weather station

    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 se...see more »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.

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!

    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
