Hello All! Sort of a newb to this so bare with me...
So I decided to make my own breadboard arduino in preparation to create some actual circuits using an Atmega328 with the arduino bootloader.
I have placed the Atmega328 in my arduino duemilanove to load the Blink sketch. I have loaded the sketch sucessfully and the led blinks as it should.
When I place the Atmega328 in the breadboard ( built with the schematic http://www.ladyada.net/images/boarduino/boarduinosch.png given on ladyada.net ) it runs the program ( blinks the led ) but the chip runs rather warm. It' not a power source issue as I have the Breadboard receiving its power from my arduino board that is plugged into USB.
[u]Adittional info That may help diagnosis:[/u] - Pin 21 (AREF) is not connected to anything. - using 22pf disc capacitors on the oscillator and reset button. - using a 16.00Mhz oscillator.
[u]Question(s)[/u] What are the benefits and detriments to disc capacitors? What is the difference?
