Summary of the Circuit

This circuit is designed to control a 2HP well pump and multiple 24V irrigation valves using a Wemos D1 Mini microcontroller. The Wemos D1 Mini interfaces with a 4-channel 5V relay module to switch the irrigation valves on and off. A separate 5V 2-relay module is used to control the well pump via a 220V well pump relay. The power supply for the circuit is a 5V, 5A unit that powers the microcontroller and the relay modules. A power transformer steps down 220V AC to 24V AC to supply the irrigation valves. Splicing connectors are used to manage the wiring connections throughout the circuit.

Documented Code

No code was provided for the microcontroller. The operation of the circuit is dependent on the embedded code that would be running on the Wemos D1 Mini. The code would typically initialize the digital pins connected to the relay modules as outputs and then control them to switch the relays on and off, thereby controlling the well pump and irrigation valves. Without the code, the specific logic and timing for controlling the devices cannot be documented.
