This is a minimal Arduino project, the components used were:
1 x ATMEGA328
1 x Medium Breadboard
---- Some breadboard jumper wires.
1 x Red LED
1 x 1k Resistor
1 x 100nf ceramic capacitor
1 x FTDI programmer
The completed minimal breadboard Arduino should look like this:
Image by Fritzing software.
The FTDI and LED are optional. The FTDI is used to add new code to the ATMEGA328, while the LED attached to digital pin 13 could be use to test the setup. In order for the FTDI to be able to program the ATMEGA chip a 100nf ceramic capacitor is required, if the capacitor is not there the FTDI wont be able to upload the code to the micro-controller. The Rx from the FTDI is connected to the Tx of the micro-controller and the Tx from the FTDI is connected to the Rx of the micro-controller. The ground and 5+V from the FTDI are connected respectively to the breadboard.
