The outputs include switches to turn on heat or air conditioning, a keypad for direct input and a Bluetooth interface to connect to a smartphone app. Guidelines: Don't write the code. Provide a structured description of what is to be coded Write the specification so someone could write the code without asking for clarification. Be complete but keep the document to a reasonable size. Don't write a flow chart, text only. You can write the specification in a structured natural language
