K3

Perhaps the colors can help get the wiring correct in the enclosure.

Placed in an enclosure

I let an RPUno^5 operate three Orbit 58874N valves from 2/5/2017 to 3/29/2017. Most days the three valves were operated ten times each. The runtime got changed a few times as I got drip zones set up for a garden. Some days the K3^1log does not have data for various reasons.

An interactive Command Line Interface for Solenoid control is wired to LED's to see its function. In my reset all video each solenoid is cycled twice (opps), but the logic control is working. After connecting the K3 board I fixed the control program so it cycles each solenoid once as seen when RPUno with K3 video is seen.

program (save/load settings to/from EEPROM) and connected some of

Orbits (58874N) latching valves (which work for me with a 24V 50 mSec

pulse). Have a look at the video of RPUno (modified ^4) with K3 controlling some latching valves.

Update2: Added a day/night state machine to the Solenoid program, which loads saved settings from EEPROM after a morning (debounce) at the start of each day, and starts their operation.
