Part 1 of this three-part series introduced the technical and engineering steps necessary to design an LED display system from individual LED lamps. Part 2 provided the remaining steps needed to ...

LED signage and matrix displays are an integral part of the 21st century landscape. Their quality is becoming so good that it’s becoming increasingly difficult to distinguish LED images from ...

[Stan] built this LED matrix using a 16×16 grid of RGB LEDs. He built the hardware and wrote some subroutines to randomize the colors. He’s not using PWM because frame buffering is not feasible for ...

We’ve seen some great Halloween-related hacks for costumes, including the gaping hole one over at Make, but we at GeekTech are fond of wiring up our pumpkins as well (we even made a Pumpkin PC). Mike ...

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 ...
