Goals


16-08-11
Students are able to build, program
and document a little
microcontroller system.
microcontrollers sensors

Attending the practical lessons is
obligatory.
Not possible to attend the practice?
contact dhr Stokkink
Failing to attend more then 2
practical lessons, there will be no
grade!
During the practical lessons the
logbook will be assessed

Assessment



16-08-11
The logbook will be looked at as an
assessment
Home-orders will be assessed
sufficient or insufficient.
All home-orders must be sufficient
in the end.
5
Responsibilities


16-08-11
The student is responsible for the
hard-en software, there are more
groups who must use it.
Defects must be reported
immediately.

Each week an introductory assignment
At the beginning of the week the home
assignment must be shown on the test
board. Is must be through a flowchart and
the program in your logbook.
