How to make Motion Sensor Using Arduino - Robomart

In this tutorial you set up a motion sensor to your Arduino and a motion is detected or when to turn off the LED will give a simple example. With its new speed sensor wire and how to program the Arduino ? Well look no further. The principle is used in many fields of automatic door open , such as smart homes .... Arduino, HTML and CSS tutorial , keep the following .




Step 1: REQUIRED ELECTRONICS

 The parts required for this basic complex are

Motion sensor
Jumper wire
Breadboard
Arduino uno
LED 

Step 2: HOW TO BUILDING THE  ELECTRONICS

If possible Place your controller on a breadboard! we are using Arduino micro so it is very convenient to put on a breadboard if we are not using a micro then  we will need jumper wires to connect your Arduino to a breadboard so we can plug our output devices and sensors in more easily.
After all you are located , you can go ahead with the motion sensor and the ground should be labeled the pin Arduino you are going to place a wire from the ground.
You are going to take a pin on your Arduino and you let me use your PIN number five pins on the Arduino to a blank " out " label to connect the speed sensor are pin out.
Then you come out with the Arduino that is positive five volts to the VCC output speed sensors are going to connect the VCC output .
Next on my breadboard, LED is the positive side the lead now or go ahead and place both you and your leadership led to it being a small scar on the side of the one are the same for your breadboard Arduino place on the ground downside downside plug in, you then empty on the ground on a pin for making motion sensor LED pen to the ground can use a jumper wire to the positive Arduino LED Run a wire from the side.
I used this for a pin number 7 . We now proceed to the wires and controller programming , go to the next step .

Step 3: HOW TO CODING
int motion = 5;
int motionLed = 7;
void setup() {//ok i need to state what each pin will be doing. the led pin will//be an output and the motion pin will be an input.
pinMode(motion, INPUT);
pinMode(motionLed, OUTPUT);}
void loop(){ //what will happen in the sketch //if motion is detected we want to turn the led light on //if no motion is detected turn the led off //you also need to declare a variable to hold the sensor data long sensor = digitalRead(motion); //then the if statement to control the led
if(sensor == HIGH){
digitalWrite (motionLed, HIGH); }
else {
digitalWrite (motionLed, LOW); }
}
