Hello everybody.
I been working with an arduino uno for a few years now and i decide to make them standalone.
So i bought some Atmega328P-PU and start putting them on a breadboard with a Crystal and a few capacitors
I have loaded the BLINK example onto my Atmega chip and this works fine, The led blinks with an interval of aproximilly a 1/2 second.
Now this works i have solderd one onto a PCB.
I used a Voltage regulator (L7805ABV) to make 5 volts out of 12 volts.
the Atmega does get power and ground and the Crystal is also correct installed.
But when i start it up the led on pin 13 doesn't light up.
When I touch the plastic of the Atmega chip the led does ligt up, But flashes way to fast (Not the 1/2 a second it should).
does anyone have an idea what is going wrong here?
I thank you in advance.
Yours sincerly,
Bob
