Arduino OLED Rlelay and DS18B20 to control heater element of a 3D printing Filament dryer.

/*

  • 3D Printing Filament Dehydrator Control Module

  • This sketch will control the heater element(s) of a standard Food Dehydrator

  • to enable drying various 3d printing filament to their suggested dryinh tempertaure and time.

  • An Arduino is used to display and capture menu selections through 3 momentary push buttons.

  • Pre stored values for targetted temperature will be compared to the inputs from a DS18b20 Dallas digital temperature sensor.

  • Results of this comparision will then be used to control the heater element relay via 5v signal.

  • ####-WARNING-#### Timer function is ONLY for reference, NO ACTION to the dehydrator will be executed by the module through timer functions.

  • The reason for this non-action is to prevent the filament to re-absorb humidity in case of long running time after auto-shutdown of heater element.

  • Buzzer / Alarm might be added in the future
