There’s a circuit right out of the textbooks ... found himself in with this custom LED battery level indicator. As the video below unfolds we learn that he didn’t start exactly from scratch ...

You can learn more about these less-known features by referring related articles/ tutorials/datasheets published elsewhere in this website/internet. As a bonus, you can build your own LED display ...

This is a very simple LED dimmer circuit which has 2 transistors, 1 resistor and 2 potentiometers. Typical segment displays LEDs consume around 25 mA for each segment and should be limited to this ...

Frank’s LED dimming circuit is based on a 555 Timer chip. The fixture is only pulsed long enough with the 12 volts to establish the desired brightness level. This method overrides the “avalanche” ...

In recent years, transparent LED screens have become a focus of efforts to make flexible video displays using substrates like glass and clear plastic. Such screens are made from networks of highly ...

IC1a is an integrator whose job it is to "smooth" these pulses into a voltage level ... previous circuits, the display can be operated in either DOT or BAR mode and has 10 and 20 LED variations.

Inspired by printed circuit boards, the building block of all electronics, a Dutch designer has created an LED-based light installation ... The entire composition will be on display at the Design ...
