HC-06 Bluetooth Module: Introduction, Interfacing & Its Applications.With this duration, we calculate the distance in centimeters and display it via serial communication if it’s less than or equal to 20 cm.Using pulseIn(), we measure the time it takes for the ECHO pin to go HIGH, representing the time it took for the pulse to return.We trigger the sensor by setting A1 (TRIG) to LOW for 2 microseconds, then HIGH for 10 microseconds, and finally LOW again.It repeatedly sends out ultrasonic pulses and calculates the distance based on the time it takes for the pulse to bounce back. The loop() function is where the magic happens.Specifications Power Supply: 3.3V 5V Operating Current: 8mA Working Frequency: 40Hz Ranging Distance : 3cm 350cm/3. It is a perfect ultrasonic module for distance measurement, proximity sensors, and ultrasonic detector. A1 is set as an OUTPUT pin, connected to TRIG, while A0 is set as an INPUT pin, connected to ECHO. It can measure from 3cm to 350cm with the accuracy up to 2mm. The setup() function defines the pin modes. We initialize the serial communication for debugging purposes using Serial.begin().It is compatible with 3.3V5V device like Arduino, Raspberry Pi, etc. A01NYUB is an waterproof ultrasoinic sensor module with 7.5m effective ranging distance. Ultrasonic Sensor SRF04 2.2 The Integrated Circuit 2.3 Algorithm. Ultrasonic distance sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse. Here’s a brief explanation of the code’s functionality: Arduino Uno R3 and a LCD (liquid crystal display) screen are required. The ultrasonic sensor’s TRIG and ECHO pins are connected to analog pins A1 and A0, respectively. In this code, we utilize the Adafruit Motor Shield library to control the motors. The distance is calculated using the video camera’s images calibrated with the ultrasonic. Serial.println(distanceCm) // If the distance is less than or equal to 20cm, display it The robot system is based on Arduino and a video camera that works together with an ultrasonic sensor. To make the connection easily we recommend using our Arduino RS485 Shield. It can not be connected directly to an Arduino. HOME COMMUNITY FORUM WIKI BLOG PRODUCT LINES EDUCATION.
