    Dear All,

    For my project I really need some help. I want to run some dry tests before building further with my car project.
    For this project I need some components on a breadboard. My skill in programming is better than building advanced electronic circuits. This is the reason why I ask you to examine my components and discuss if this combination will work without problems!
    So when I order it and receive the items I wont be disappointed when it doenst work!

    Underneath is a list with components which I have choosen.

    It is for a connection between a FT2232H and a Amel Atmega 644P. First I want to test my programming skills just on the Atmel and further on in the project I will try to program a I2C into the building blocks.

    For the FT2232H I found the following socket:

    For the USB FT2232H:

    Module:
    http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&...68-1030-ND

    2 resistors for the I2C:
    2 times resistor 10k
    http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&....0KQFCT-ND

    For the Atmel Atmega I have choosen for the folling materials:

    Chip:
    http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&...44-20PU-ND

    Crystal 20Mhz:
    http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&...me=X195-ND

    resistor 10k
    http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&....0KQFCT-ND

    capacitor 0,1uF
    http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&...78-5096-ND

    2 times a capacitor 22pF
    http://search.digikey.com/scripts/DkSearch/dksus.dll?WT.z_he...11A220JAR+

    Test circuit to prototype:
    http://www.micahcarrick.com/files/atmega8/tutorial_3/circuit.png

    5 times a resistor 1k
    http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&...00KQFCT-ND

    5 blue LEDS (I dont know if they will burn bright with just a VCC as input):
    http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&...me=P468-ND

    It will be placed on a:
    http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=922354-ND

    With:
    http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=B-24-1-ND
    For connection to the breadboard

    I hope someone on this forum is so kind to examine my choises and give me feedback if something is wrong.

    Thank you in advance.

    Should do fine. The blueLED's are very efficient - you will be able to see them.
