Step 1: Connect the Ultrasonic Sensor to the Jumper Cable (Ground + VCC)
Step 2: Connect the corresponding Jumper Cable ends to Arduino UNO R3 board at pins referring to 5V and GND.
Step 3: Connect Pins Tr1g and Echo on the Ultrasonic sensor with Jumper Cables
Step 4: The other end of the jumper cables connect to Pin 7 and Pin 8 Respectively on the Arduino.
Step 5: Ultrasonic measures the nearby distance:
Step 6: Measurement displayed on Graph in cm:
Step 7: Ultrasonic measuring farther object:
Step 8: Measurement displayed on Graph in cm. We can observe the shift in readings:
Code for running the Ultrasonic sensor:

if (distance >= maximumRange || distance <= minimumRange){ /* Send a negative number to computer and Turn LED ON to indicate "out of range" */ Serial.println("-1"); digitalWrite(LEDPin, HIGH); } else { /* Send the distance to the computer using Serial protocol, and turn LED OFF to indicate successful reading. */ Serial.println(distance); digitalWrite(LEDPin, LOW); }
Step 1: Connect the IR Proximity Sensor to the jumper cables:
Ground should connect with Ground on the Arduino Board
5V should connect with 5V on Arduino Board.
Step 2: We can observe in the pic below, our Arduino UNO R3 is having all female pins:
Step 3: Hence , we need to use berg sticks to convert it to male
pin. This is because, we use the jumper cable to connect to other IC's
and Jumper cable are having female pins.
Step 4: Insert the Berg Sticks into Female Pins of Arduino:
Step 5: Connect the jumper cables such that the 5V cable from the IR proximity sensor connects to the 5V on the Arduino UNO R3 board and GND from the Sensor connects to the GND on the board:
Step 6: Connect Arduino Uno R3 board to the computer using cable.
Step 7: The Red LED on the proximity sensor glows when the finger obstructs the path of the sensor.
Step 8: The Red LED stops glowing on the finger being removed from the path of the IR proximity sensor.
Step 1: We need to make the connection as per the below circuit:
Step 2: Connect the jumper cables to the Piezo Buzzer. Connect he positive cable to the longer wire on the Buzzer.
In case of sensors, positive terminal is the longer wire.
Step 3: Connect the Positve jumper cable to Pin 9 and the negative jumper cable to ground:
Always remember, when connecting cables, positive will connect to positive and negative to negative / ground.
Step 4: Connect the Arduino UNO R3 to the computer using the USB printer cable :
Step 5: Upload the following code to Arduino: This is for providing power supply to the Arduino UNO R3 board.

This time received the message:

The blinker is blinking every 1 second. It was already blinking.
Hence let us now modify the program for making it to blink every 3
seconds.
Step 14. Make the
program to blink every 3 seconds:
// the setup function
runs once when you press reset or power the board void setup() { // initialize
digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT); }
// the loop function
runs over and over again forever void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH
is the voltage level)
delay(3000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by
making the voltage LOW
delay(3000); // wait for a second }
We find that the orange LED in Arduino is now blinking every 3
seconds:
