Today the project moves in a different direction as we hammer out a good share of the hardware work on the project. No code today... I have been planning this, and amassed some parts already for this project; collecting more as we move along.
This begins with the outdoor rated liquitite case and materials used to make the inner cover and mounting. With the base fabrications completed, the first of the pieces are assembled onto the base. These pieces on the bottom layer are AC power, and AC/DC regulation. This along with the relay for the valve are put in place, the ESP32 breakout module sits on a level over the AC/DC Power. Another layer off to the left of the ESP32 board will be more standoffs for a layer in support of the solenoids relay board.
Multi pin plugs will be installed on the bottom of the box in support of the valve and water meter. Room exists for another connector. A small antenna was installed for the ESP32 wifi. The board for the solenoids also has room to support a factory default button through the front cover.
Careful measurements were taken to cut out the size needed for a 20x4 LCD screen, any mistakes means redoing the front cover. Plastic standoffs were used and cot off from the front to make a mount for the screen. I've also added an encode/button combo as this will add input value at the box.
AC voltage has been routed to the Relays as well as the addition of a 2A breaker to the project. 30v AC lamps have been added to the relays as a good test indicator for development. The water meter emulator and the valve have been added to the connectors on the bottom.
All components currently connected are added and checked and working which brings this chapter to an end.
