Eight-pin microcontrollers offer numerous peripheral features. However, the maximum number of I/O pins available is often limited to six, since two pins would be required for the chip's power supply.

The structure of a segmented LCD display essentially consists of the components featured in Figure 1. It includes: two polarizers rotated 90 degrees from each other to polarize light coming into the ...

Instrument designs featuring a digital display may benefit from a secondary display that provides an analog version of the displayed parameter. A bar-graph display provides an easily interpreted ...

Makers and developers that enjoy using the Arduino platform to create projects, may be interested in a new Arduino smart display called the Pixel. Pixel offers an Arduino Zero compatible development ...

Inexpensive OLED displays with I2C interfaces abound, but there is a catch: they tend to be stuck on I2C address 0x3C. Some have a jumper or solder pads to select an alternate (usually 0x3D), but they ...

The most common method for interfacing multiple switches—multiplexing— allows for the connection of (N/2)2 switches with N microcontroller IO lines. The method described below, which has its roots in ...
