There is a varied and growing market for LEDs in wearable applications, ranging from head torches and miners’ helmet lamps, through backlighting for head-up and near-to-eye displays, indicators for sports and medical monitoring devices, to fashion accessories and clothing. While LEDs have already become a popular embellishment, like sequins or beads, in fashion garments, they […]

Project description: In this project, 8 LEDs are connected to PORT B of a PIC microcontroller. Also a push-button switch is connected to bit 0 of PORT A using a pull-up resistor.. When the switch is pressed the LEDs scroll to the right. Hardware: The circuit diagram of the project is shown in Figure 1.

There may be a lot of RGB LED Drivers out there, but this one is a bit different, its versatile, small, cheap, and is simple to control. A potentiometer with built in switch is used for the controls. A quick press, switches between color cycling and solid color select modes. Pressing in on the dial and

This Design Idea demonstrates a new method of driving six LEDs with only two I/O lines from a microcontroller, and so is particularly suitable for any pin-limited chip. It uses a pair of I/O lines combined with a pair of complementary bipolar transistors.More than one LED can appear to be lit by multiplexing. A previous

MUNICH — At Electronica last week, the LED manufacturer Everlight introduced what it claims to be the world’s first colour-temperature tunable LEDs in a simple chip on board (COB) package. After brightness dimming, tunable color temperature is a feature that allows end users to tune the warmth of the light they receive. Typically, this feature
