I have weird problem. I'm testing very simple programs which turns the LED on specific pin. Everything working correctly as long as the atmega is glued to the arduino uno board.
I removed the atmega and placed on breadboard to check the if the same program is running without the board and it is not working.
I checked 4 times, everything is connected properly.
On breadboard I provided power, 5V on pin 7 and grouns on pin 8. What am I missing here?
But it is pointless. Arduino is a board with make prototyping easier. But I dont want to use board anymore and move solution on breadboard and You want to tell me that, this is nessessary to clone arduino on breadboard. I bet all wee need it's just power.
I'll take a piece of that bet' having built many breadboard 328's. The Uno bootloaded chip has to have the crystal. It needs pull up on reset if you want it to work. And connect 5V and gnd to pins 20 and 22.
And decoupling cap on the power pins.
