Teaching method
There will be a weekly one-hour lecture for the presentation and discussion of concepts to be used in laboratory sessions.
The weekly laboratory sessions have a duration of four hours. During each session there will be some periods for discussing concepts to be applied.
Each class will have a maximum of twenty students divided into ten groups of two students each.
Each group will have a workbench with a test bench (with breadboard, several voltage sources, signal generator, etc.), oscilloscope, multimeter, adjustable voltage and current power sources, signal generator, computer (with software LabVIEW) and a Arduino Uno board.
Evaluation method
The evaluation is made by written tests and an evaluation of the final project. The final grade is obtained using the following weightings:
25% - Programming microcontrollers test score;
25% - LabVIEW programming test score;
50% - Project evaluation score.
The final project is evaluated by a demonstration of operation (35%) and by a written report (15%).
The scores are assigned on a scale from zero to twenty values. The intermediate calculations will be made with the scores rounded to one decimal.
To be admitted to the final examination is necessary a number of attendance greater than or equal to two-thirds of the number of practical classes, have a weighted average of the tests scores greater than or equal to 9.5 and get a rating greater than or equal to 9.5 points on project evaluation.
