This running LED or LED chaser is a good project for beginners in the microcontroller technology. It is easy to build, and the assembler program code can be easily adapted. This running LED light has 15 red 3mm LED’s. The 15 outputs of ports B and D are used to drive the leds. The LED’s light up […]
This small project let you make running leds. For this project you need a attiny2313 microcontroller and 8 leds and 8 resistors. The leds can be programmed so that they show differrent patterns. Hardware The leds are connected to PORTB of the microcontroller via the resistors that limit the current to 20mA. The project can
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
Previously before 10-15 years the majority of electrical lights were either light bulbs (with yellow light) or tube-light sticks (with white light). The major disadvantage of these lighting devices was they consume more electrical energy (in terms of Watt) and gives less luminance (brightness). Light bulb wastes their most of the energy in form of

Now a days LED light bulbs are becoming more and more popular because they have several advantages. Some of their advantages are listed below · Their energy (electrical) consumption is much more less · Their luminance is more · Their intensity can be varied · Their life time is more So if LED lights are
The aim of the project is to make a portable LED display from SMD LEDs and to display the custom programmed patterns at our command. The core application of the project is to act as a portable display for event organisers or exhibitionists or consultants to make announcements at their mobile facilities. This can also be
ATmega16 has 32 I/O pins to communicate with external devices. Before interfacing with external devices, these pins must be cofigured as input or output pin. This article demonstrates the basic I/O operation of ATmega 16 using LEDs. All the four ports can be configured to read an input from some external device or to give

For understanding the human needs a system must be able to take input from user. The devices which can be used to take input for a system are keypad, touch screen, etc. In the article LED blinking, the microcontroller drives the LED or in embedded language the microcontroller was set to give o/p, this article gives
