Connect MK AVR to power?

Power is 5 Volts, current of 2.25 Amps. If you put a resistor of 200 Ohms will that be enough? Microcontroller Atmega 328P U. Here are its pinouts(correct it at all?)5afc07fb2b1a3293488345.png
Will it be sufficient to sum up the food only to GND and VCC, or other such insights also need to power?

Resistor nafig not needed. Or are You of the sect of those who see the voltage source 2A and thinks that the source of their always pouring into consumers?

Between the VCC and GND pins, between AVCC and GND ceramic capacitors. Don't forget to bring feet for programming and to do the RESET with the button. (look for patterns)

For Pinout, see datasheets at the office. sites: ww1.microchip.com/downloads/en/DeviceDoc/ATmega328...

Well then why when I hooked up the segment indicator(green color), 5 Volts and 2 Amps, it just burned for half a second lit yellow and then just pfft all, no indicator. But if you put a resistor of 200 Ohms is pfft - dewayne.O commented on June 5th 19 at 21:36
generally to begin with you should understand that the chip and diode of one p-n junction a few different things...

Chip power that they are given in some datasheets, i.e. in this case, a voltage in the range of 1.8 - 5.5 V for this stone. More than she had intact m/s does not take itself, if you are in external circuits roughly will not mess up by putting the exits on the ground, for example. :)
All you need is already implemented in the chip and its consumption is no more than a dozen or two mA in the supply voltage range.

The LEDs are also powered by the currentthat if you do not limit begins to kill the device. In Your case the resistor acts as a current limiter, because the led is scheme is usually not embedded and You need to take care of stabilization. :) - caden_Wintheiser commented on June 5th 19 at 21:39

AVCC also need to power. This is the analog power for the ADC, but it some legs feed on another PC
AVCC to +5 Volts? - dewayne.O commented on June 5th 19 at 21:38
Yes - caden_Wintheiser commented on June 5th 19 at 21:41
read more about the operation of the software comparator in the AVR. You can apply for the necessary AREF reference voltage. - dewayne.O commented on June 5th 19 at 21:44
