Arduino Watering project - Build the heart of my system

🧭 Direction

After a few weeks on this project I now have a clearer idea of how I want to shape everything.

🔌 TCA9548A I²C multiplexer — soldered

Soldered the pins for the TCA9548A I2C/IIC 8‑channel multiplexer expansion board.

🧰 16‑channel CD74HC4067 — soldered

Also soldered several 16‑channel analog/digital multiplexer breakout boards (CD74HC4067).

For soldering I used the tripod I normally use when tying fishing flies — works great as a helping hand.

🖥️ Big display test

Next step was getting everything to talk together. Here’s a quick big display test.

🧩 Chassis layout

Started placing components in the chassis, making individual cases for each module so it looks clean and remains functional.
