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 ...

Now you can always know the exact time. With this design you can have an atomic clock in your room. Isn’t that great? Read on to know more. Now you can always know the exact time. With this design you ...

The moving-dot display has some benefits over the bar-graph display: It better indicates the location of a detected object in sonar and radar applications; it needs only one LED’s current-limiting ...

Seven-segment displays are needed in many instrument designs. In conventional microcontroller-based designs, four output port lines are allocated for one seven-segment display. Figure 1 shows the ...

Why do LED displays still feel limited? A design approach removes size, wiring, and power limits, helping engineers build ...

Around these parts, we generally celebrate clever hacks that let you do more with less. So if somebody wrote in to tell us how they used multiplexing to drive the front panel of their latest gadget ...
