| You need to ensure that the Phoenix connectors are in place before plugging in the wires to the respective pins. If you havent link |

There is something missing here...

| Connect the red and the blue wire to any one of the 8 pairs of `LATCHING OUT` pins. In this example we will use `1N` and `1P` of your Edge Control board. Latches allow you to store the state of the pins based on the previous output. As the valve doesnt come with internal drivers to store the state of the motor, we will use the `Latching_out` pins (instead of `Latching_out_cmd`) that are the ones that include drivers on the edge control. |

I'm not familiar with latches, so I don't fully understand this paragraph. What are we trying to do? Why do we need to store the state'

| Inside the `loop()`you will add the instructions to open and close the Valve. `Latching.channelDirection()` is used to control the signal to a particular pin using the parameter `LATCHING_OUT_1` and its direction using the parameters, `POSITIVE` or `NEGATIVE`. Hence, if you want the valve to open you will use the instruction, |

I don't understand the concept of "direction" hence I'm struggling a bit to understand this paragraph.

| Latching.channelDirection(LATCHING_OUT_1, POSITIVE); | ||
| Latching.strobe(4500); | ||
| delay(2500); |

Why the delay if we already use strobe()'

| ### 3. Connecting To A Power Source | ||
|
|
||
| The Valves require a power supply of 9 - 12 V and you can either use a power supply or a 3 cell lipo battery to provide the required voltage. Power sources can be connected to the onboard relay ports of the edge control board. Connect two jumper wires to the **GND** and **B** pins of the **Relay ports** |

How much current does it need to source?

Does this power the board or the valve or both?
