He is still updating his GIT items.

I wonder what happened.

I don't think your reset line resistor goes to +5 volts.

I think you are missing the ground from the Arduino to your board.

On your picture I see nothing plugged into pin 29 of the 328 where it is plugged into the protoboard.  You schematic is calling for the pullup resistor for the -RESET line.

Why are you using the pin out the way that you are?

I would think that it would be better to bring in the 3.3 at the top of the board on the opposite side.
Same thing with the ground.  Bring it in on the top and on the other side.
Shorter runs.
Slide all the signal pins down 2 positions.

Also, are you going to put screw holes on the board so it can be mounted?
6  Using Arduino / Installation & Troubleshooting / Re: Atmega328 on breadboard not working on: January 20, 2014, 02:39:57 pm
Well, dang. That solved it.

I've been using a tutorial which stated 10ohm, which should have been 10Kohm.

Thank you!
Which tutorial were you using?  Maybe it can be fixed.
7  Using Arduino / Microcontrollers / Re: Out of memory Attiny2313 on: January 02, 2014, 09:03:07 am
have you thought about using the ATTINY4313.  It has twice the memory.  Same pinout.

The fungus link cost is $5 with shipping.

If you want more, this is from the same company, 5 for $15.

Please understand that the process you follow may be OK for an Arduino device that you will build and use in your home BUT you should not be using these "procedures" in real products. 

If you design a circuit for a commercial product and then test it under varying conditions, you don't, at a later time, go through and remove capacitors.  If it is working, don't fix it!

Any update?
11  Using Arduino / Microcontrollers / Re: unable to upload programs to bread board microcontroller on: June 30, 2013, 03:33:45 pm
Here is one solution:

One problem is that you are missing the 10K ohm resistor to +5 on reset, pin 1.

There could be other problems though.  I can't tell at this point.
13  Using Arduino / Microcontrollers / Re: Motor Shield Direction not working on: June 07, 2013, 12:44:25 pm
So, what happened?
14  Using Arduino / Microcontrollers / Re: Motor Shield Direction not working on: May 31, 2013, 10:16:38 am
Yes, it can be a problem with current and voltage requirements.
The max voltage from a USB port is 5 volts.  There are voltage drops in the H bridge.
What about current?  How much current does each motor take?

Turn the motors on with the program and measure the voltage across the motor leads.

How much current does each motor take?

If the motors work directly off the battery but they don't work when using the USB, then most likely the USB can't supply enough power to run the motors.
