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.

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 ...

Using a single microcontroller port to drive a multi-digit LED display to help engineers with those last-minute design ...

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 ...

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 ...

Most digital timers require a set of dip switches or rotary BCD encoders to preset their interval. But those techniques consume eight or more inputs from a microcontroller's (MCU's) I/O lines. To ...

These days they’ve been replaced with character LCD displays or even brightly colored graphical displays, but if you’re trying to display data on one of your projects, there’s nothing like the classic ...
