Designing LED Matrix Circuit

LED matrix is the number of LEDs arranged in columns and rows. Those LEDs are then used to display images or text that usually displayed with certain animation effects. Therefore, the LED matrix is often referred to as the Running Text or Moving Sign. Arrange LEDs as matrix MXLED is a simulator of the circuit […]

Running Text on LED Matrix

In the example in Showing images on LED matrix using simulator, the note is displayed as an image. First we create a text image, then we create a constant from the text image. After that it displayed as an image. Displaying text in this way is only appropriate if the text to be displayed is […]

Showing Images on LED Matrix using Simulator

Controlling the LED matrix is actually almost the same as controlling seven segment. The difference is that the LEDs of seven segment are organized into seven sections which could form the figures. While the LED matrix, LEDs are arranged into a matrix that can be referenced by column and row. The columns on the LED […]

3 Digits Counter

A friend asked me for help to create a program to perform calculations that can go up or down. The data displayed on a three-digit seven segment. Meanwhile, the buttons mounted on the port 3 used to raise or lower the count. Actually, he asked me to place the digits control using P0, and P2 […]

Seven segment simulation for digital clock program with hours-minutes-seconds display

Seven Segment is one of the most common components used primarily to display data in the form of numbers. For that, Microcontroller Project also provides a simulation for seven segment, namely SSLED.exe. Seven segment simulation provided by the SSLED.exe has eight-digit in multiplex manner. Multiplex technique is the most commonly used because of its compact […]

Running LED simulation on Microcontroller

Early game which is always done by people who are just learning the microcontroller is lit the LED. Although the first time we usually just turn on the LEDs moving to the right or left only, and usually things like that would be boring, but it is very important to understand how to program the […]
