lm386 amp Audio Amplifier

LM386 IC Audio sound Amplifier home made schematic and circuit diagram

This is simple Audio power Amplifier project that you can make at home easily. We will make this project using a lm386 IC which is a 8 pin IC. You can make it as small as a match box. Due to its tiny size lm386 is perfect for various projects like radio amp, tiny Guitar amp amplifier. lm386 amp is a simple Low voltage Audio power amplifier used in various audio applications. You can find schematics and components required for making this amp here.

Simple Flashing / Blinking LED with a 555 timer Circuit

555 timer IC flashing LED with 555 circuit diagram

If you are looking for a Simple circuit to blink a Light emitting diode without complex circuitry, For some small projects or to  impress your friends maybe then probably small and easy circuits with 555 Timer would be a better option to start with, a Simple Blinking circuit. With help of a Small 555 timer chip you would will be able to that just fine. 555 timer is one of a very low cost and basic IC used now a days. You can make it at very easily here.

USB DC Motor Controller using PIC18F4550

Controlling a DC motor from computer with USB Interface.

This a small project on controlling DC motor with USB pic18f4550 interface board with L293D motor controller for beginners. In robotics and controlling stuffs one of the most basic thing is to control your own applications like DC Motors , Stepper Motors , Servo (with pwm) etc etc,In this tutorial A small application [C#] is controlling pic18f4550 USB interface board with computer, enabling to control my board with keyboard to interface with L293D motor driver.

Introduction To Microcontroller

What is a microcontroller ? Microcontroller in simple term refers to  a small computer on a single chip. Its like an artificial mind for any intelligent devices which is responsible for taking decisions. [eg your robot needs to take decisions, then a microcontroller would do that for us.] Microcontroller can be programmed , and has its own programming language and compilers. Hence in our robotic applications it is going to serve as a mind which will be responsible for taking all decisions.

Identify Anode Cathode of Led ( Light Emitting Diode )

How to Identify the polarity (cathode/anode) of a LED , How to identity the -ve and +ve (cathode anode)polarity of a LED without using multimeter.LED's or Light Emitting Diode's don’t come with any labeling on it to identify Cathode(-ve,GND) or Anode(+ve).So for identification , led’s comes with a unique way to identify its terminals as Anode or Cathode.

C# Software and Firmware, USB INTERFACE BOARD
