Microcontroller

Pay special attention to the component’s markings indicating how to place it on the PCB. Polarized components can only be connected to a circuit in one direction.

Locate the microcontroller. This component is polarized, which means we need to take extra care to place it in the board properly. Notice the notch on the image below.

Atmega328

Looking at the bottom of the board, insert the microcontroller . Make sure that the notch on the chip aligns with the white silkscreen on the board. To avoid having it inserted backwards, we cut off a pin.

Locate Atmega328 on Board

Flip the board over and solder all of the microcontroller's pins to the board.
