Help on "Arduino on breadboard"

-

hi.
i'm trying build http://siliconrepublic.blogspot.in/2011/02/arduino-based-pc-ambient-lighting.html ambient light controller pc. worked flawlessly on arduino uno :). next step make using "arduino on breadboard" http://arduino.cc/en/main/standalone. bought blank atmega328 chip , burned arduino bootloader (for board "arduino duemilanove w/ atmega328") onto using arduino ide , usbasp; , know has been loaded led @ pin 13 blinks, said in here: http://arduino.cc/en/guide/troubleshooting#toc1 (under subheading "bootloader").
then made usb-to-serial converter using ft232rlhttp://www.sparkfun.com/tutorials/108; drivers didn't install on pc (windows 7 x64). suspect overheated surface-mount ftdi chip , killed while hand-soldering it. :(
now i've got usb serial converter bridge: http://www.silabs.com/products/interface/usbtouart/pages/default.aspx has st232cn chip on it.
i'm not sure if should use max232 ic convert ttl logic level suitable tr/rx pins of atmega328? tx/rx pins usb-to-serial converter @ ttl logic level or of rs-232 standards +/- 12v?
and tried circuit: http://arduino.cc/en/uploads/main/arduinoseverinoschematic.png using usb-to-serial converter, had no idea "programmer" should select in arduino ide. tried of them, , got error:
code: [select]
avrdude: stk500_getsync(): not in sync: resp=0x00
which correct programmer should select circuit? , why error?:~
thanks in advance :)

does bootloaded atmega328 chip work in uno?

does computer recognize homemade usb-to-serial converter (with ft232rl)?

if you're trying upload sketch , not burn bootloader, changing programmer shouldn't make difference.

can try verbose upload (hold shift+ press upload) , copy error messages here? using 12v logic usb-to-serial device? check atmega328 datasheet - don't want putting 12v signals tx rx pins. might able away using resistive divider correct logic levels, otherwise max232 fine.

last suggestion. try adding couple of 1k pull-up resistors on pins 2 , 3 of atmega328 (tx , rx pins) on breadboard before uploading.

Thread: PKI Client 5.00 install (for eToken Pro)

-
my company uses aladdin etoken pro authentication on vpn connections. etoken requires pki client application on client machine before os recognize it. app , token work fine on xp, use ubuntu on laptop. aladdin has offered linux version of client, rpm. convinced our internal guys rpms, , i've been trying work couple days. begin with, hp pavilion dv4-1435dx laptop running jaunty 64-bit. - started out converting .rpm .deb using alien: code: sudo alien -d pkiclient-5.00.28-0.x86_64.rpm - worked fine , got nice little .deb - next, ran .deb install client: code: sudo dpkg -i pkiclient_5.00.28-1_amd64.deb - , executed without errors/issues. pdf rpm said there should launcher @ applications > etoken > start etoken pki client, didn't exist. figured might because installed deb instead of rpm. bounced box, still wasn't there. no big deal... - install network manager can configure vpn connection use token: code: sudo aptit...

ATmega2560-Arduino Pin Mapping

hi community, in last days working on project using arduino mega 2560. on planning pin using found bugs in atmega2560-arduino pin mapping . if right there labels (such pwm) in 'mapped pin name' @ wrong row ( mixed pin numbers right one...) in attachment openoffice calc , pdf file corrected table. ( hope ;-) ) i post here tab separated table : code: [select] arduino mega 2560 pin mapping table atmega 2560 pin out arduino mega function nr name function function function mapped pin name function function datasheet 1 pg5 oc0b digital pin 04 pwm 2 pe0 rxd0 pcint8 digital pin 00 rx0 (usart0 receive pin, programming data input or pin change interrupt 8) 3 pe1 txd0 digital pin 01 tx0 (usart0 transmit pin or programming data output) 4 pe2 xck0 ain0 (usart0 external clock  input/output) 5 pe3 oc3a ain1 digital pin 05 pwm 6 pe4 ...

Crossfader Arduino Tutorial

-
hello i'm super newb please don't bash me much. i'm using led's , i've connected them correctly (finally) , wondering why program here ( http://www.arduino.cc/en/tutorial/colorcrossfader ) doesn't work? say's haven't declared crossfade. read directions on top , said crossfade needs used list order of colors. isn't declared in main part (void loop() )? or need declared before? nevermind void on bottom , needed before voidloop. lol anyways playing rgb led's wondering if has specific way of making them fade in , out different colors? (brightness , color mixing) code: [select] /* * code cross-fading 3 leds, red, green , blue (rgb) * create fades, need 2 things: *  1. describe colors want displayed *  2. list order want them fade in * * describing color: * color array of 3 percentages, 0-100, *  controlling red, green , blue leds * * red red led @ full, blue , green off *   int red = { 100, 0, 0 } * dim white 3 l...
