requires lower voltages to operate

LEDs require lower power to operate. Voltage is irrelevant and in some cases, incorrect.

Figure 4-2

Arrows on diagram point to pins AREF and 12.

They should point to pins GND and 13.

"Turning on and off the pin at will now let us translate these..."
Should be "lets".

"Example 03C final code"

It currently says:
if (buttonValue == HIGH && oldButtonValue == LOW) {
ledState = 1 - ledState;
delay(10);
}

I think the correct code should be:

if (buttonValue == HIGH && oldButtonValue == LOW) {
ledState = 1 - ledState;
}
delay(10);

In the book it says:

"Because the Arduino has two GND pins, ..."

The newer Arduino UNOs however have 3 GND pins.

// If the button is held for more than 500ms

I am at page 60 on iBook version

Believe he should have

if (val == 1 && (millis() - startTime > 500) {

I believe you should be looking at the present state of the button. One phrase he doesn't use is Toggle. I believe the initial intent was to turn it on with one push/release, and turn it off with the next push/lease. If the release comes much later than the push then the bulb also fades.

1st paragraph

In the description of a MOSFET it is stated that it is "an electronic switch that can be driven by applying a voltage to one of its three pins, each of which is called a gate". However, if I understand correctly only one of the three pins is referred to as a gate. The Note on MOSFET later on the same page confirms this.

Both leads to the fan motor appear to be connected to 9 V.

Figure 5-7

Component between middle (drain) MOSFET pin and +9V rail is not identified. I used a 1N4004 diode and the motor from a scrapped computer CD door mechanism.

Should circuit should have a pull-down resistor (1Kohm or so) from pin 9 to PWR ground on Arduino board to keep it from floating?

Figure 5-7

DC motor control circuit goes wild during software upload. Needs a pull-down resistor (10K ohm or so) from pin 9 to ground.

I asked this as a question in the errata earlier; but now I see it is a serious technical mistake in the book.

After the first comment block of code

Several imports need to be loaded as Processing no longer uses them as default imports:

"import processing.serial.*;" should be updated to

import processing.serial.*;
import java.net.URL;
import java.net.URLConnection;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.StringTokenizer;

Does not work with the current version of Processing.

Must use version 1.5.1

Figure 5-4

The Kindle version from December 2012 repeats Figure 4-6 in Figure 5-4 instead of showing the correct figure. It shows a pushbutton on the breadboard rather than the LED that the example uses.
