Welcome Machine : 5 Steps

This project Use Led bulb and the Piezo to make a machine. The function of this machine is that when people can in your home the piezo will make the noise so that you can know it. Also, there will be a Hi that use the LED light bulb.

Step 1: Prepare for Material

Part list:

1 x Arduino LEONARDO
13 LED light bulb
7 Resister
1 x Ultrasonic Distance sensor
1 x Pizeo
plenty of wires

Step 2: Programming the Arduino

void setup() { digitalWrite( 6 , LOW );
