Initial support for the YS-100 Soil Moisture Probe. Readings does not seem right, but if this is a software or harware probelem, I am not sure. I need to do more tests on this.
Added tests/moisture_test/moisture_test.ino - a test sketch to read the YL-100 moisture probe.
Added reading of moisture probe #1. The others can be added easily by setting their respetive pins and uncommenting the lines doing the reading of the probes.
Reads all moisture probes and logs them
