| <note>The remote access lab will not let you use the most common approach towards tracing, as you're physically away from the device and do not have access to, e.g. its serial port or debugger. For this reason, understanding actuators (mostly displays) is essential because the only way to monitor execution is to observe the results remotely via the video stream.</note> | <note>The remote access lab will not let you use the most common approach towards tracing, as you're physically away from the device and do not have access to, e.g. its serial port or debugger.

| <note important>Note that video streaming has limitations, such as the number of frames per second, resolution, common use of many devices (dynamic video colours problem) and stream quality. That impacts how you write the software, e.g., using larger fonts and not changing display contents rapidly because you may be unable to observe those changes remotely.</note> | <note important>Note that video streaming has limitations, such as the number of frames per second, resolution, common use of many devices (dynamic video colours problem) and stream quality.

| The following scenarios explain the use of hardware components and services that constitute the laboratory node. It is intended to seamlessly introduce users to IoT scenarios where using sensors and actuators is an intermediate step, and the main goal is to use networking and communication. Besides IoT, those scenarios can be utilised as a part of the Embedded Systems Modules. | The following scenarios explain the use of hardware components and services that constitute the laboratory node.
