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 LM3914 LED bar graph driver was an amazing chip back in the day. Along with the LM3915, its logarithmic cousin, these chips gave a modern look to projects, allowing dancing LEDs to stand in for a ...

LEDs offers a combination of flexibility and efficiency unmatched by conventional forms of lighting, and are being adopted in architectural- and stage-lighting applications because they emit highly ...

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 ...

Usually, an MCU is considered a digital device. By default, its output voltage level can be either high or low and nothing in between. With the requirement to create an LED brightness control, the ...
