"Ohm's Law"

Suggest changing "mA/hr" to "mAh" since the "/" implies "divide by" whereas the unit is of course mA multiplied by hours. Also page 32.

"Selecting a Relay" 2nd para

The example "... if you want to control a 240 V, 40 A contactor with a 24V coil that draws 36 mA, then a relay rated for 100 mA contact current should do fine.” may be confusing because (if I am not confused) it involves a relay driving a relay but this concept or its purpose has not been introduced. Suggest that a more intuitive example be used, e.g. relay driving a light bulb. Further, the subsequent concept "“In this case either a driver IC or a transistor driver as described in the section Controlling Relays With Low-Voltage Logic will be needed.” may compound this confusion: it is ambiguous whether the IC or transistor driver is intended to drive the first relay that drives the second relay or directly drives the second relay instead of the first relay.

Section headed "RS-232"

Suggest adding something about MCUs and other modules that use RS-232 but with TTL level voltages (e.g. Common with Arduino boards and shields) and how this is convenient but prone to smoke if the two are mixed.

2nd para after Figure 14-14

Suggest inserting ", including start, stop and parity bits" after "baud, which is the number of bits per second”. This might prevent the reader inferring that "bits per second" means "data bits" and to make the important distinction between baud and data bits per second, preparing them for the next para, which adds detail to that concept.

"DTE and DCE"

1. Suggest changing "does not refer to" to "does not necessarily refer to". 2. From the sentences "The DCE devices provide the channel between the endpoints using some type of communications medium. For a system using modems this would typically be a telephone line.” it is not clear whether the DCE is the modem or the telephone in this example, though it reads as if the DCE is the telephone line whereas (my understanding is that) the modem is the DCE.

Para before Figure 14-18

"“It does not show how the handshake lines would need to be connected.” made this reader wonder why not? Suggest adding a forward reference to the subsequent treatment of this.

Table 14-19 and surrounds

(This is an enhancement suggestion, not an error, so if the development process is beyond enhancement suggestions, please ignore!) Given that outside of the Americas, the ISM 433MHz band is commonly used instead of 902MHz for remote controls etc., it might be helpful to include it in Table 14-19 and perhaps add a column that qualifies the region to which each row applies? For example, when ordering one of those simple ASK/OOK rx/tx modules, a choice of 433/434MHz, and 315MHz are available. A novice reader may appreciate a hint as to why they would choose one over the other. And/or, a reference to somewhere that sets out the regions and the bands (e.g. http://en.wikipedia.org/wiki/ISM_band) could assist.

Note from the Author or Editor:
Excellent suggestion. Author will revise as appropriate.
