Question 1

what are three ways to use ADC data from an LDR?

Answer 1

1. luminance - level at any point in time
2. proximity - sudden light change (set point)
3. dosimeter - accumulated level of light (area under the graph)

Question 2

when connecting outputs to a PIC microcontroller, what additional components are required? (3)

Answer 2

1. to limit current - transistor for LEDs
2. to provide sufficient current - transistor for motors
3. to block direct current - capacitor for speakers
