Hi All,
I am thinking of setting a simple circuit to water my potted plants e.g. at 7am and 7pm.
I need the following.
1. Simple circuit powered by 6-9V battery to turn on either a DC motor or a DC normally closed valve.
2. Preferably an off the shelve parts.
Thanks in advance.
Special thanks to blocco a spiral for the water level sensing circuit. After 2 years, it still working and still using the same 9V battery.
