Exercises
Exercise 1
Der skal udvikles et indlejret system til pulsmåling - se tegning. Det elektriske signal (se illustration), kan opfanges via to elektroder der typisk placeres på brystet eller fingrene. Diskutter detaljeret hvordan sensor input og signal behandling skal foretages for at I kan lave software'n der tæller, udregner, og udlæser hjertefrekvensen (pulsen) i "beats per minute.
(Svar og hints: se TI note og HBM Design Project )
Exercise 2: In relation to your projects, discuss the requirements for sensors and actuators for your applications
- What are the properties of the sensors/actuators provided with the NXT kit ?
Exercise 3: Discuss the Lejos API? Draw a complete class diagram.
