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. ...

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...

Introdution ESP8266 With Node MCU

Image
I  am going to give you the introduction of ESP8266 microcontroller. How to get started with this ESP8266? We are going to use here the Arduino IDE to write custom firmware that is gonna be download on the board & execute it. The material required for this tutorial are:- The micro USB cables. The ESP8266 development board with translator chip by silicon lab. Yeah, I have taken this solderless breadboard because it is easy to use & I prefer this. Another thing we require is the ESP12e module. we are going to need the Node MCU Lua ESP12e ESP8266 Wifi development board. This is the open source IoT platform. It has several benefits of using this board like it is having necessary circuitry to manage the voltages. And it is really very good that it manages 3.3v on the board. The USB to UART interfacing makes it very simpler to connect the computer. To configure ESP8266 we are going to use the AT commands are sent via serial UART interface. this is the...
