<wrap info>NOTE</wrap> The class has an associated development kit.
Before the first class, use the
[[id2:bom:start|kit parts list]]
to verify that your kit has all the parts.

Class content is delivered **by video**.
It will normally not be repeated during classes.
You therefore **must** download and watch each week's videos **before** attending the class.

You should also download and try to complete each week's lab experiments before attending the class.
The deadline for submission of experimental results is the first Monday following the class.
/*Material for Friday's class will also be made available on Monday.*/

The class periods on Friday will be for answering questions about the course content
and for assisting anyone who cannot make progress on the experimental part of the class.

Class summaries are posted below with details of homework assignments, etc.
