Different Electronic systems operate in different level of voltages. Most commonly the digital electronic systems like microcontrollers and microprocessors operate in 5V or 3.3V. Industrial Level Control devices like PLC, HMI etc. have an operating voltage of 12V, 24V etc. The loads (LED indicator) and sensors, that are used to interface with a PLC, also have a nominal…
Making our projects Wireless always makes it to look cool and also extends the range in which it can be controlled. Starting from using a normal IR LED for short distance wireless control till an ESP8266 for worldwide HTTP control, there are lots of ways to control something wirelessly. In this project we learn how to build wireless projects using a 433 MHz RF module…
Any color is made up of three colors: Red, Green and Blue, using a simple RGB LED you can generate any color. But the limitation of RGB LED is that it has three separate LEDs inside it and requires three Pins of any microcontroller to operate one RGB LED. So it is not possible to connect hundreds of LEDs with one microcontroller.
To overcome this…
Operational Amplifiers (Opamp) has so many interesting applications, and we have already created many circuits using op-amps. Today we are going to study one more application of Opamp which is to add two or more input voltages and the circuit is called Summing amplifier or Opamp Adder. Here we will use LM358 Opamp to demonstrate the Adder Circuit.

LED interfacing is the first thing one would try to do while getting started with any microcontroller. So here in this tutorial, we are going to interface an LED with an 8051 microcontroller, and we will write a C Program to blink the LED. We have used a very popular microcontroller, AT89S52, of the 8051 family, by ATMEL. LED interfacing with 8051 microcontroller…
The reliability of any electronic device depends on how well the hardware protection circuits have been designed. The end user (consumer) is prone to make mistakes and it is the responsibility of a good hardware designer to protect his hardware from any mishappening. There are ample types of protection circuits each with its own specific applications. The most common type of…
After developing few popular robotic projects like line follower robot, edge avoiding robot, DTMF robot, gesture controlled robot, etc. in this project we are going to develop a bluetooth controlled robo car. Here we used a Bluetooth module to control the car, and it is also an android based application.
Components Arduino UNO DC…
It is always interesting to build things that could be used in our day to day life and it gets more interesting when the same can be built easily at a very low cost. In this tutorial we will learn how to build a simple yet powerful MP3 player that could play any MP3 song, the volume and track can also be adjusted with the help of push buttons. With some extra effort you can…
Rain alarm is an application which detects the rain water and blows alarm. They are useful devices and play an important role in various industries such as automobile, irrigation, and wireless communication. Desiging a rain alarm system is quite simple and we have designed here a demo rain alarm project with the help of 555 Timer IC.

In this DIY project we make a 3-Channel Arduino Relay Shield Circuit for relay based applications. We designed an isolated PCB for 3 relays. By using this Arduino Relay Shield, we can operate 3 AC appliances at a time. We have put a two pin screw terminal blocks (Neutral, NO) for connecting appliances. Here we have provided PCB layout, circuit…
In this tutorial we will learn how to use an External Interrupt in PIC Microcontroller and why/where we will need them. This is a part of the sequence of PIC Tutorials in which we started learning PIC Microcontrollers from scratch; hence this tutorial assumes that you are familiar with how to program a PIC MCU using MPLABX and how to interface an LCD with PIC. If not please…
Stepper Motor is a specially designed motor which rotates in steps. Speed of stepper motor depends on the rate of electrical signal applied to it. Different patterns can control stepper motor’s direction and rotation type. Mainly two types of stepper motors are available, Unipolar and Bipolar. Unipolar is easier to operate, control and also easier to get. Here in this…
