About: i am an electronic lover who want to make something superb.

Hello friends Arduino is a good friend of student, but sometimes it become complicated when we want to use ATmega8. Arduino NG comes with atmega8 but it will take 6 seconds for Turn On, but here is a solution. Just follow some steps.

(Must Use Arduino IDE 1.0.6)

Step 1: Material Required

1. Arduino UNO

2. ATmega8 Microcontroller

3. USBasp Programmer

4. Jumper Wire (Female to Female)

Step 2: Connect the Circuit (ATTENTION)

circuit shown in video is not correct please refer this circuit (sorry)

Step 3: Bootloading.....

Please Watch My Video

1. Download AVRDUDESS (Link Below)
http://blog.zakkemble.co.uk/avrdudess...

2. Install Program.

3. Open Program.

4. Select USBasp from drop down menu.

5. Click detect (for detection Microcontroller)

6. Change the values of FUSE BITS as shown below.

L:0xFF

H : 0XDE

E : (empty)

LB : 0x3F

7. Click On "Write"

8. Click On "Read"

9. Select Bootloader File @ Optiboot_atmega8.hex

10. Click On Program.

11. Now ATmega8 is Bootloaded.

Step 4: Attach Atmega8 Board to Arduino

1. Copy this

atmega8o.name= Atmega8 Optoboot

atmega8o.upload.tool=arduino:avrdude1

atmega8o.upload.protocol=arduino

atmega8o.upload.maximum_size=7680

atmega8o.upload.speed=115200

atmega8o.bootloader.tool=avrdude1

atmega8o.bootloader.low_fuses=0xbf

atmega8o.bootloader.high_fuses=0xdc

atmega8o.bootloader.path=optiboot

atmega8o.bootloader.file=optiboot\optiboot_atmega8.hex

atmega8o.bootloader.unlock_bits=0x3F

atmega8o.bootloader.lock_bits=0x0F

atmega8o.build.mcu=atmega8 atmega8o.build.f_cpu=16000000L

atmega8o.build.core=arduino:arduino

atmega8o.build.variant=arduino:standard

2. Goto Arduino@Hardware@Arduino and open Boards.txt

3. Paste copied data at the end.

4. Save and close file

Step 5:

1. Open Arduino (Must Use Arduino IDE 1.0.6)

2. Select Board (Arduino Optiboot-Atmega8-16)

3. Upload the code
