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.

This application required more flexibility than the LM3914 offers, and it uses a circuit based on an Atmel AVR-family ATTiny13 microcontroller, which features 1 kbyte of program memory; a four-channel ...

The moving-dot display has some benefits over the bar-graph display: It better indicates the location of a detected object in sonar and radar applications; it needs only one LED’s current-limiting ...

The algorithm in this microcontroller design this design drives an LED matrix and provides digital-voltage-readout and bar-like dot displays, showing dots for a graphical output if the input value is ...

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 ...

[Joe] tipped us off about his 112 LED coffee table. This 12-ups the LED matrix from Friday and 31-ups the Shiftbrite table. Driving this grid is an ATmega328 in i2c slave mode. It listens for display ...
