All we need are the following components- A breadboard, a led, a power jack, a IC socket, a microcontroller, few resistors, 2 regulators, 2 capacitors. We can also design our own Arduino by following the schematic given by the Arduino vendor and also available at the websites.

serial.begin(baud rate): Sets the beginning of serial communication by setting the bit rate.analogWrite(pin, value): Writes the value to that pin.analogRead(pin): Reads and returns the value.pinMode(pin, mode): Sets the pin to input or output mode.digitalWrite(pin, value): Writes the digital value to the given pin.digitalRead(pin): Reads the digital value at the given pin.

Thus the code is uploaded by the bootloader onto the microcontroller.
