Setting up IR sensor connection to Atmega 328P is very simple. Beside VCC and GND pin, the sensor has only one output pin that should be connected to one of digital pins of the Atmega 328P.

HC-05 has red LED which indicates connection status, whether the Bluetooth is connected or not. Before connecting to HC-05 module this red LED blinks continuously in a periodic manner. When it gets connected to any other Bluetooth device, its blinking slows down to two seconds. This module works on 3.3 V - 6V but you can use only 5V DC. this module use any Serial 

AMS1117 is a popular SMD package 3-pin voltage regulator that is available in many models for fixed and adjustable voltage requirements. The IC can deliver a maximum current of 1A and the output voltage can vary from 1.5V to 5V. It also has a low drop out voltage of 1.3V when operating at maximum current. pin number 1 GND, pin 2 OUTPUT, pin 3 INPUT.
