- You Reply: I already am supplying power with 5v through to the Arduino Uno power jack and 9v to the relay shield jack.
Are you saying that I should put i.e. 9v in the Arduino Uno jack and 0v in the relay shield jack? - You Reply: Wow, thank you so much for making so much effort to help me. It's just amazing to see :)
I really do appreciate your efforts here! :)
I have now done exactly at described in the wiki, and none of my shield relays are working :(
I tested my method on a simple Grove relay i bought a while ago and made it work right away.
I believe i am doing everything right - so i guess the board must be faulty. - You Reply: Problem sovled!
It seems I was a bit too hasty testing the second moisture sensor - it works perfectly on both boards.
My first sensor is fried though, dont know how that happened - but anyhow, Im happy now

Yes - I have always only used the orange cables on both of the sensors/arduinos.
The output values i gave you came from running the samplecode in the soil moisture sensor wiki.
Interesting enough the samplecode for the DHT11 (temperature and humidity sensor) on both sets it says
"dht11 start condition 2 not met".
Could it be possible those pins on both my ecoduino's are not working properly ?
