洞察力 - LED点矩阵显示如何工作
Light emitting diodes aligned in a form of matrix constitute a dot matrix display. It is commonly used to display time, temperature, news updates and many more on digital billboards. Dot Matrix Display is manufactured in various dimensions like 5×7, 8×9, 128×16, 128×32 and 128×64 where the numbers represent LEDs in rows and columns, respectively.Arrangement of the LEDs in the matrix pattern is made in either of the two ways: row anode-column cathode or row cathode-column anode. In row anode-column cathode pattern, the entire row is anode while all columns serve as cathode and vice-versa pattern is there in row cathode-column anode. LED wafers are glued to the bottom of the segments and glow when powered ON. The interesting part is that 35 LEDs are controlled by using a combination of 14 pins. Conductor tracks are laid all over the board to power each LED. Let’s proceed to know in depth about how a dot matrix display works.
音乐运行的LED
This circuit will light up different LED’s according to the audio signals which are feed through condenser microphone. When sound intensity is low few LED’s will glow as intensity of sound increases number of LED’s which glow also increases. Important feature of this circuit is we have not use any special running light IC like LB1405. We have made this circuit with the help of seven channel Darlington array IC ULN2003. ULN2003 is a monolithic high voltage and current Darlington transistor array. It contains seven NPN Darlington pair on a single IC. It also have high output voltage with common cathode clamp diode for switching inductive load. And collector current rating of each Darlington pair is 500mA. Another feature of ULN2003 IC it has 2.7kW series base resistor for each Darlington pair so that it can directly connected to TTL or 5V CMOS device. Read more to find out how this circuit is assembled and how it is made to work.
DIY – Table Lamp
Ever wanted to make your own table lamp? If yes then you have come to the right tutorial! This project shows you how to make table lamp using a bunch of LEDs and 555 Timer circuit. Our first problem is that we can’t give 12V directly to an LED which would simply burn it. Well you may say that adding a series resistor would solve that problem but let’s see what happens when we do that.
使用Arduino的点矩阵显示
This project is based on Arduino Platform. In Electronics, there are many display devices available in or market like Liquid Crystal Display, Seven Segment Display, Dot Matrix LED display, Graphic Display etc. and they are used to display some information in many places like railway station, bus stand, mall, multiplex, hospital, school, colleges and many other places.Here, In this circuit Dot Matrix LED display is used for displaying information. The method of displaying message on dot matrix displays is same as seven segment multiplexing. Column of dot matrix is rotating very fast means greater then seventeen times in a second and same time changing in row data causes display some information on it. Due to the vision of our eye it looks like stable.
Controlling RGB LED colour using Atmega16- (Part 19/46)
This tutorial will give you a brief introduction to the concept of colors and how different colors can be produced using RGB LED. The color would be controlled using an ATMega16 microcontroller.RGB LEDs are basically the combination of the 3 LEDs (Red, Green and Blue) fused into a single package. It consists of four pins totally out of which three of them for the three different colors. The 4th pin is common for all three colors and it’s either Cathode or Anode.
