The main objective is to build a super-modular system that allows controlling the peripherals as simple (and cheap) as possible, transferring all intelligence to a raspberry pi controling all what happens in the pool.
We often see lots of equipment that is responsible for two or more tasks, more or less autonomously (saline chlorinators that control pH, intellegent pumps that control filtering and other equipment, smart peristaltic pumps with time control or probe connection, etc.). This equipment only partial resolve main automation tasks and dont allow any type of expansion or improvement. This project propose that the peripheral be as stupid (and cheap) as possible, dedicating himself ONLY to his main task. A pump: only filter when told, a saline chlorinator: create chlorine when told, a peristaltic pump, inject when told,…
There are also very modular (and usually quite expensive) professional systems that share this same perspective, but they often have the problem of forcing all components of the same brand to be purchased. If you have already made a strong investment in equipment of this type, this project is probably not for you.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
