Running LED or LED chaser Using AVR
The main objective of this project is build a Running LED or LED chaser Using AVR
COMPONENTS :
1.ATTiny2313 micrcontroller
2.CRISTAL 10MHz
3.CAPACITOR 22pf X 2
4.POWER SUPPLY +5V
5.RESISTOR 1K X 16
6.LED (15)
DESCRIPTION :
*This running LED or LED chaser is a good project for beginners in the micro-controller 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 in a pattern that can be made in the program code
*The LEDs run back and forth
*With a push button you can select another pattern at which the LEDs runs
*There are three running LED patterns which you can run: with one led, three leds and five leds.
HARDWARE DESCRIPTION :
*The project uses the ATTiny2313 micrcontroller but the ATTiny2313 can also be used
*The AVR port can draw 20mA current so you only have to place a resitor at the port of the AVR to limit the current to 20mA.
* The LEDs are connected to ground so when the output of the port is high the LED will go on
*The circuit uses a ceramic resonator of 10Mhz as oscillator
* When you use ATTiny2313 you can discard the resonator because they have an on chip clock sourceSOFTWARE DESCRIPTION :
*The program code is written in assembler
*You can use AVR Studio to write the software
