At a Glance If you are starting out with microcontrollers & electronics, breadboard-friendly switches & potentiometers come in handy. Discrete LEDs make great output devices, but LED bar graph & ...

A total of 10 I/O pins (D2–D11) of the Arduino UNO is used to drive a 10-LED bar graph display (LDA-B10ZX). Here, the bar graph is wired to digital pins of the Arduino through 470R current-limiting ...

The circuit in Figure 1 uses only five I/O lines to drive a dot- or bar-graph display of 20 LEDs. Although this version of the design uses a small and inexpensive one-time-programmable microprocessor, ...
