Detecting Obstacles and Warnings with ultrasonic sensor

-


Components Required:

1x Arduino

1x Ultrasonic sensor

1x Buzzer

1x Jumper wires

Application:

https://www.arduino.cc/


Code:

int trigPin = 6;

int echoPin = 5;

int buzzPin = 2;



void setup() {

  Serial.begin(9600); 

   pinMode(buzzPin, OUTPUT);

   pinMode(trigPin, OUTPUT);

  pinMode(echoPin, INPUT);

  // put your setup code here, to run once:


}


void loop() {

  long duration, distance;

  digitalWrite(trigPin,HIGH);

  delayMicroseconds(1000);

  digitalWrite(trigPin, LOW);

  duration=pulseIn(echoPin, HIGH);

  distance =(duration/2)/29.1;

  Serial.print(distance);

  Serial.println("CM");

  delay(10);

 

 if((distance<=10)) 

  {

    digitalWrite(buzzPin, HIGH);

}

   else if(distance>10)

 {

     digitalWrite(buzzPin, LOW);

   }

}


Your project is all set...!!!

ESP32 Error: A fatal error occurred: Timed out waiting for packet content.

This article provides a complete solution for the most common Fatal error that usually occurs while uploading the code to ESP32. In this article I have interfaced DOIT ESP32 devkit V1 module with MG995 servo motor on GPIO = 18. You can use any module of your choice. Servo Motor Connections: Most analog servo motors like the MG995 use a 3-wire color-coded cable for interfacing. Although the color-coding is not an official standard many manufacturers use the same colored wires: 1)Orange – The PWM servo control input. This is a logic-level signal, and most servo motors can accept 3.3-volt logic as well as 5-volt logic. Some models, especially 270-degree rotation servos, use a White wire for this connection. 2)Red – The servo motor power supply input. Generally 3.3-5 volts DC, but be sure to check first. 3)Brown – The ground connection. On some servo motors, this is a Black wire ESP32 PWM Most micro controllers can be used to generate PWM signals and the ESP32 is certainly no ex...
