Question about 50$ robot ( my first electronic projet at life )

[SgtToad]

Hello,

I'm a totally newbie of making eletronic circuit. But i want to learn and with this great site i learn already lot of thing. I'm from Québec city, Canada and my english is not very well. I understand very well but i did'nt write or speak very well.

I do all the electronic things. Test and re-test conectivity before plugin-in battery pack. No smoke or spark when i plug the battery power pack.
I add the ATMEGA8-16PU to the socket and power it without any problem. The VCC pin receive +5V.

I installed avr studio and plugin the AVRISP MKII. I get the blinky orange led bug. The help file talk about a reverse wiring problem or a pull resistance problem.

I got 3.8v at the reset pin of the connector it is enough ?
It's my wiring are reversed ( i did'nt tink so ) ?

Thanks for your help.

it is hard to tell but looking at the pic it looks like your capacitors negative lead is connected to the far right of the volltage reg, it should be in the middle

I test and retest the connectivity.

The image show how things are connected. I do a connectivity test on each of the colored link and test the voltage all around. I redo a schema of how i wiring that... i think all its ok, maybe someone can look and tell me if i make a mistake.

Hi,

 Did you actually program the board or not?
If not then the led will blink about randomly anyway. You need to program it to make it work

[SgtToad]

i'm trying to program the board with the hold_servo.hex file.

I get an error message in avr studio ( see attached file )

[SgtToad]

Ok...

I have completely rebuild my ISP head, re-verify all connectivity to be conform with the 50$ bot schema, all was ok.

But i get the flashing orange led with avr studio.
Reading the AVRISP MKII userguide i see i can use the stk500.exe command line it's what i do... surprise green led appears.

I have an other problem now...

There was a problem with the programmer firmware:

Just upgrade it and it should work.
