Maybe it's been asked before but can't find it.
I would like to accomplish the following 2 things using 1 Arduino Uno Rev3
- RTC DS1307 Real Time Clock Module
- Grove - Relay SKU: 103020005
To open / close the Grove - Relay at set times/hours, daily repeat.
20 hours closed and 4 hours open (daily)
Running along on the same Arduino Uno Rev3: (this has nothing to do with the above)
- Gravity: Analog Capacitive Soil Moisture Sensor - Corrosion Resistant
When I've have set the needed values it needs to indicate:
- Green led = Not dry
- Red led = Dry
Can this be done? (sorry for my ignorance just a newbie on the block)
Thanks in advance (tips, examples are more then welcome)
