Requirements & Specifications - Mickyleitor/RollerShutterControlPanel GitHub Wiki

PAGE IS STILL WORKING IN PROGRESS

User Requirements

  • User can control the shutters manually via buttons.
  • Arduino can interface with shutter via Radio frecuency (HTR108 device), see hacking RF shutters article.
  • The system should move the shutters automatically according to an alarms table.
  • Four buttons will be used in order to accomplish with HCI compliants (Left/Up/Down/Right).

Technical Specifications

  • A low cost high compacted microcontroller, like Arduino Mini Pro.
  • A AC-DC Converter to power the microcontroller.
  • A LCD 16x2 I2C device.
  • Four mechanical buttons.
  • An USB-TTL converter in case an OTA update on the software is needed.

Limitations

  • Space limitations compacted in a 13x6x4 cm box-sized.
  • Power consumption by arduino, LCD, buttons and required ICs.
  • Logic voltage levels between LCD 5V and Arduino MiniPro 3.3V.
