I have been working with this for over three weeks. I have a tried and true working example from the , as they say, “As seen on TV”
DroneBot Work program that was proven to work by the [shop]
However it has been my Non-Lucky-Streak lately to have proven things not working, for me anyway!
I have learned in the past it is usually something I overlooked or something stupid I did not think of.
Here is the completed program, with only one change, I added an LED to show that something is working, My first attempt was to use the DHT-11’s that I had in stock. NOTHING WORKED, EVEN THE LED. After much work I added an 4.7K pull up to the DHT and now the LED did flash as it should have but now I only had zero.zero C with 32.0 F, but no reading on the Humidity output. On the DHT11 there was a 10k PU on the module already.
I tried two other DHT11’s and another Arduino UNO with the same results. I used just about every port that would be within reason with the same NG results. I rebooted the computer with my big foot and rechecked the XOD for updates. Still the same bad results. Don’t forget this is a PROVEN working program that DroneBot shows it working as it should. Here is all the further information I can give you all.
I ordered two NEW DHT-22’s, from a know good distributor, They had a 4.7K pull up on the data line but no power LED. I changed the layout for the DHT22 and received the same results. You can see the output on my pictures. One with the Square wave output high and one with it low. Oh yes, on Every OTHER transitions the C/F changed. I wonder why?
Oh well, here is everything I can give you, if you need something more, please ask. I am open for any and all ideas…
And here is my layout.
I hope I gave you enough information to build this and see what the %&*@ I am doing wrong.
I know it is something I am overlooking and I hope you do not make a Ass out of me.
