Smart Gardening #3: Wiring with microcontroller on Prototype Board

Now is time to connect all sensors. Let’s get hands dirty and start soldering on prototype board.

Recap from last time:

Smart Gardening #2: Concept Design by drawing Block Diagram



  1. Define Arduino Micro Pinout


2. LCD Display to microcontroller

3. Light Sensor Module

4. Moisture Sensor

5. Pressure, Temp + Humidity Sensor

6. Prototype Board


Soldering Tips

  • I like using un-used resistors to run wires on prototype board because I can hold it with the resistor while soldering – wire gets hot!!!
  • When soldering male headers, use 2-pin jumpers to hold it to avoid heat.

Next steps

  • Time to hook up with PC and power on
  • Start Programming and test the sensors individually
