Moth Trap Hatch Controller

A compact, automated hatch controller for a moth trap, designed for the Seeed Studio XIAO (SAMD21 Cortex-M0+). This project combines simple electronics, robust firmware, and 3D-printed parts to automate the opening and closing of a hatch for insect trapping or similar applications.

Getting Started

Prerequisites

• PlatformIO
• Seeed Studio XIAO (SAMD21)
• Standard SG90 hobby servo
• Trigger button/sensor

Setup

1. Clone this repository:

   git clone https://github.com/ScionResearch/moth-trap-hatch.git
   cd moth-trap-hatch

2. Open in PlatformIO (VSCode recommended).
3. Connect your Seeed XIAO board.
4. Build and upload:

   pio run --target upload

Usage

• The servo is attached to PIN_SERVO (default: pin 10).
• The trigger input is on PIN_TRIGGER (default: pin 9).
• When the trigger is pulled LOW, the servo moves to the DOWN position; otherwise, it stays UP.
• Debounce is handled crudely with a 1s delay.

3D Printing

• STL files for all mechanical parts are in hardware/3MF files/.
• The full assembly is in hardware/Moth trap assembly.f3z (Fusion 360 format).
