Automatic Cold Frame Hinge

The goal of this project is to create a powered hinge for a cold frame or green house that automatically opens and closes based on temperature. An arduino was used for the control board to read the temperature sensor and instruct the servo motors when to operate.

Parts Used:

  • Arduino Uno or Nano
  • Servo Motor
  • 100 uF capacitor
  • 4.7k Ohm Resister
  • DS18B20 Temperature Sensor
  • I2C OLED Screen
  • 10K Potentiometer
