Hello!
Recently purchased materials listed for the Soil Moisture Sensing Project. Wanted to know if the RedBoard is compatible with the Blynk app and if so how would connection be possible? I am fairly new to the use of Arduino and attempting to display values through the widgets instead of the LCD.
Thank you! - atalal
Hello atalal.
The RedBoard on it’s own isn’t compatible with the Blynk app since it doesn’t have a way of connecting to the internet. You could give the RedBoard internet access by connecting it to a WiFi board but sadly we don’t have a guide that shows how you would get that working.
You could use a board like the [ESP8266 Thing Dev but the Thing Dev’s analog input can only take up to 1 volt so you’d need to build a [voltage divider to scale the output from the soil moisture sensor to a 0 to 1 volt range. It would take a few extra resistors and a bit of soldering, but would work.](https://learn.sparkfun.com/tutorials/voltage-dividers)](https://www.sparkfun.com/products/13711)
