Arduino Watering project #- Multiplexor with LEDS

🎯 Goal

I’m planning for ~9 soil‑moisture sensors, where each array index represents one sensor.

🔌 Why a multiplexer?

To expand the number of analog/digital inputs, I’m using a multiplexer so the Arduino can read all sensors.

💡 Channel test (LED blink)

Testing that each multiplexer channel is selected properly — if it is, the LED blinks.

📹 Demo

🔧 LEDs for plant indicators

Soldered some LEDs that I’ll use as per‑plant indicators.
