ESP8266 Node MCU & Ultrasonic HCSR-04[ Accurate measurement ]

Image
             This Tutorial, We Are Going To used ESP8266 12E Node MCU with Ultrasonic Sensor Module (HC-SR04).  HC-SR04 Is Used To Measure The Distance Between 2cm to 4meter With Ranging Accuracy Up to 3 Millimeter. For reading the complete tutorial visit our main article. The material required for this tutorial are:- The Jumpers wires Arduino Board For (5v) Supply  Ultrasonic Sensor Module  Solderless Bread Board And ESP8266 Module It Self. The Working Principle Of Module Is Very Simple. It Emits Ultrasonic Sound Which Travelle With The Air If Any Obstacle Comes In The Path It will bounce back from the module. consider the travel time speed of the sound by this formula:- velocity=distance/time    The ultrasonic module having 4 pins GND  VCC ECHO TRIGGER As you can see the interfacing image on the video To generate the ultrasonic sound we need to send a trigger o...

Audio Amplifier using LM386 with Noise Removal

Image
Thanks for visiting my blog.  visit our main website for more more details   www.pictorobo.in                      In this blog we have to make audio amplifier using LM386 and study how to remove noise in audio amplifier.Its very simple and cheap. All this circuitary we have to make on a small mini breadboard.The circuit diagram or the connection of this setup is shown by using sketch.                                                             firstly you need 3.5mm audio jack and separate this jack from the headphones.Next we need a LM386IC.It is so popular for audio amplification.This IC needs a minimum external connection ports.This IC also battery operated with wide supply voltage range 4 to 12V or 8 to 16V depending on the different manufactures series. ...
