Debugging in the dark

Some last minute changes seemed to cause problems with color changing.

Sat in the chair in the dark, plugged into the arduino.

Fountain pit and plumbing

Used 3/4 inch conduit to run wire to junction boxes.

Used 18/4 sprinkler wire for the RGBLED, and 7 primary wires for the 6 pumps (one is the common negative wire).

Used plastic privacy lattice to mount my 3/4 inch pvc plugs (they have a flat face).

Control box assembly nearly complete

UPDATE: Keedox controllers were affected by changes in voltage or current .  Abandoned them.


Took a while to find DC motor controllers Keedox 6v-90v  15A dc motor pump speed controller) that could support 3 amp bilge pumps.

New new pumps are 750 Gph and still haven't arrived yet.

Found submersible RGB LED strip light for $20 (rated IPB 86) and a Common Anode Controller (DFRobot) for $10.86

Eliminating relays

The relay was very noisy and took up extra space.

I have switched each valve to NPN transistor and Suppressor Diode, just like the pump but just using digital On/Off instead of PWM mode.

Works better with the transistors wired with Emitter to Ground.
