CHAPTERS 6 - 8:

We'll begin Wednesday's (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 8 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)
Fig. 6-13 on Page 188 showing voltages RC Voltage decays due to charge transfer and light intensity.
PWM Command on Page 191 in Boebot text and Page 355 in the Syntax & Reference Manual.

Normalizing ambient light values for navigation on Page 194 in Boebot text, calculations on page 200.

Chapter 7 on IR Navigation
Chapter 8 on Frequency Sweep to Detect Distance
