Practical Lab

Build a Conceptual Room-Control Sequence

Est. 90 minCompetency: Define inputs, outputs, and feedback for a room control program.

Learning objectives

List the inputs (buttons) and outputs (device commands) for a room.
Define the feedback the program needs from each device.
Write the Start and Shutdown sequences as pseudocode.
Map each UI element to a variable and a feedback source.

Lab brief & instructions

Without any specific vendor, design the control for a single conference room with a display, a switcher, a DSP, a screen lift, and a touchpanel. Produce the inputs, outputs, and feedback that a program would need.

Deliverables

1An input table: button | event | what it should do.
2An output table: device | command | transport.
3A feedback table: device | status queried | how the UI uses it.
4Start and Shutdown pseudocode with state transitions.
5A list of error states and how each is shown on the panel.

Equipment-free alternative

Use a spreadsheet or notebook. The value is in the tables, not the tool. If you can write the I/O and feedback tables for this room, you can program it on any platform.

Implementation checklist

✓Inputs, outputs, and feedback tables complete.
✓Start/Shutdown pseudocode includes state transitions.
✓Each UI element mapped to a variable and a feedback source.
✓At least three error states defined and surfaced.

01. Lab outputs: input table, output table, feedback table, Start/Shutdown pseudocode, error states.
02. Map every UI element to a variable and the device feedback that updates it.
03. Define error states (display no response, network loss, source missing).
