This application note presents a reference design of 78K0/Ix2 microcontroller by controlling a high-brightness LED. It briefly describes a brief system overview of the 78K0/Ix2, as well as the control ...

Light emitting diodes (LEDs) deliver emitted light in response to current being made to flow through them, but then you already knew that, right?? If we define that the light output of an LED 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 ...

Several driver options are at the fingertips of designers with the FAN56XX family of LED drivers from Fairchild Semiconductor. For instance, driver-only parallel connection drivers with no boost ...

There are a number of ways to efficiently and elegantly limit an LED’s brightness, but [Tommy] found that using a light pipe or diffuser can integrate better with a device, especially when the device ...

This module introduces Pulse Width Modulation (PWM) techniques for Python on the Raspberry Pi. Subsequently, by using PWM we can modify the brightness of an LED without having to change a resistor.

Most of us are aware that charlieplexing can drive a large number of LEDs from a relatively small number of I/O pins, but [David Johnson-Davies] demonstrates adding another dimension to that method to ...
