Important components are prepared and used for the construction of this circuit.

Components used are PIR sensor, Neopixel(strip 4), LED, Breadboard, Arduino Unoboard and Resistor.

Step 1: Connecting PIR Sensor

Connect the Signal terminal to pin 2. Connect Power terminal to 5V. Connect Ground terminal to GND.

Step 2: Connecting LED (light Bulb)

An LED is connected with a resistor of 1kilo ohm to pin 13.

The Terminal IN of the Neopixel is connected to pin 6 with a resistor of 1kilo ohm. Connect Power Terminal to 5V. Connect Ground terminal to GND.

The circuit is completed and sensor is working as our expected result.
