Description:

• The goal of this workshop is to create a fully automated plant capable of taking care of itself as long as it's plugged in and there's water in a reservoir.

To Do:

• Create schematic
• Create build guide
• Link to editable fusion 360 files
• Create and post revised design
• Potential Revisions:
  • Might have to replace the 2n2222a for the pump with an AO3400 or other MOSFET
  • Add pull-up resistors for transistor/MOSFET
  • Add reverse current diode for pump [probably not too important]
  • Add smoothing capacitor for pump
  • Potentially add current limiting / pullup resistor for pump
  • Modify tolerances for LED Holder and the Arm
  • Modify the electronics holder so the fit better, add holder for perfboard

Materials:

Electronics

Fabricated Boards:

• 1 x Arduino Nano
• 1 x LED Array PCB
• 1 x Sisterboard

Components:

• 9 x 5730 (or other) SMD LEDs

• 9 x 50 ohm 1/4 W resistors (can increase this number to decrease brightness)

• 1 x Capacitive Soil Hygrometer

• Cabling

• 4 x 1K ohm resistor

• 4 x 10K ohm resistor

• 4 x AO3480 N-Trench MOSFET

• 1 x SMA "M4" 1n1Diode

1 x 1/8" PVC tubing cut to length

• 1 x 3D printed pot
• 1 x 3D printed LED holder

Building Instructions:

automated_plant_workshop's Issues

Lack of Editable Model Files

No perfboard holder

No Schematic

Control Timing Overflow

No Build Instructions

Poor Holder Fitment

Takes Too Long to Build and Host (Simplify Electronics)

Poor LED Fitment
