W.O.M.B.

The Willingly Overengineered Mechanical Breeder is a 'highly' advanced system designed to breed chicken eggs. The brain of the operations is an Arduino UNO or a compatible board.

Parts

• Heating Element (any)
• Motor (To turn the eggs) (any, can be a servo but the code is designed for a very slow motor)
• Multiple Temperature Sensors (Adafruit MCP9808, can be others, but the code is designed for those)
• Humidity Sensor (Adafruit DHT11, can be any, but the code is designed for this)
• Text Display (Grove - LCD RGB, can be any LCD or different screen but the code is... you get the idea)
• Relais (any, e.g. DEBO RELAIS 4ch)
• 4 Buttons (any)

Libraries

The program needs the following libraries to work:

• Adafruit MCP 9808 Library
• Grove LCD RGB Backlight Library
• DHT Sensor Library

Wiring

The schematics were created with https://www.circuit-diagram.org/ if you have improvements, you can import the existing from this repo, edit it and make a pull request if you like.

Wiring Description

• The four Integrated Circuits on the far left are the various temperature sensors, you can use more or less than currently displayed.
• The single Integrated Circuit on the bottom left is the I²C compatible LCD display
• The switches in the bottom center are simple switches to adjust the behaviour of the machine
• The single Integrated Circuit on the right side is an analog humidity Sensor
• The two relais on the upper right corner are to control the heater and the motor. (The System is designed with 4 relais while only 2 are actually used, you can expand the code to use all four or even more.)
• The Arduino Uno sits in the middle on the wiring diagram
