How to make Arduino LED Spirit level with Arduino
In this tutorial, we will learn how to make Arduino LED Spirit level using Accelerometer MPU6065.
For this we will use Arduino Nano and Accelerometer MPU6065.

Project circuit diagram is shown below.
For most of our Arduino projects that require to detect when an individual has left or entered the world , or has approached, HC-SR501 PIR sensors are an excellent choice. they’re low power and low cost, pretty rugged, have a good lens range, easy to interface with and are insanely popular among hobbyists.
HC-SR501 PIR sensor has three output pins VCC, Output and Ground. it’s a built-in transformer so it are often powered by any DC voltage from 4.5 to 12 volts, typically 5V is employed . aside from this, there are a few options you’ve got together with your PIR.
