For example, the LED bar graph uses 10 pins on the Arduino, which is great for an introductory example. However, a good point for that chapter's "Things To Try" section would have been to suggest ...

An LED bar graph comprising five LEDs, each representing 1V of input signal, represents the MSD (most-significant digit). Nine LEDs in dot mode, in which only one LED lights, represent the LSD ...

Figure 1 A dot- or bar-graph display uses either a one-time-programmable PIC12C508A or, for experimentation, a reprogrammable and reusable PIC16F84A. Use high-brightness diodes for LED 1 through LED ...
