We'll begin Monday's lecture with a discussion of the End-of-Semester Project. Details are posted here.

For the next couple of weeks we will discuss key topics from Chapters 6 through 9 in the text.

These key topics are:

Light (Wavelength & Color) and the Phototransistor (Page 171)
Basic Stamp I/O Voltage Levels (Page 176)
Ohm's Law (Page 177) and Phototransistor I/O (Page 178)
Capacitors (Page 180) - Reading Capacitor Value: 0.1 uF = 104 (Page 181)
QT (Charge Transfer) circuit for Phototransistor Light Sensitivity
RCTIME Command (Page 184) and on page 363 in Syntax & Reference Manual (P6 used as output AND input)
