Today, I am going to teach you how to make an LED matrix display using Arduino. Here we had designed a 7×5 LED matrix display but can be extended as per desire. If you are using Arduino uno board the number of rows can be extended up to 14 and the number of columns can be extended up to 6. This is because there are only 14 digital pins (D0 to D13) and 6 analog pins (A0 to A5). Thus, you can make a 14×6 Led matrix display in the…

Today in this article we are going to show you the circuit diagram and description of the 5 Band Audio Equalizer Circuit using LM833. We already control 8W + 8W Stereo with a graphic equalizer, but this time we come with 5 Band Audio Equalizer Circuit. First, let’s talk about what an equalizer is. 5 Band Audio Equalizer Circuits using LM833 Equalizer circuits are those circuits that are responsible to maintain a balance between the frequency components. The project 5 Band Audio Equalizer Circuit using LM833 divides the audio spectrum…

In this Christmas season I wanted to do some funny stuffs using arduino. Previously few years back I had made a project Christmas decoration and music using discrete components. Now I had come with funny easy and interesting project using arduino and few other easily available electronics components. The project posted here plays three different popular Christmas tone i.e. Jingle Bell Jingle Bell, wish you merry Christmas and Santa Claus is coming to town. The interest lies on the thing you have created with you owns. Definitely this project is…

Atmega16 based voting machine: Well, the key word; Corruption is everywhere. I believe it is what comes together with politics. Yes, here we present an attempt to sweep a dirt away from this system. The project is concerned with development of an electronic voting machine which is built around an AVR microcontroller, which help us to create a fair election process at least. Electronic voting machines (EVMs) have been a necessity in government elections. On comparison to traditional methods, this machine provides a far more secure voting environment and reliable…

Today, we are going to show you how to make an Arduino-based Bluetooth Controlled Car. Previously we had already posted various types of robots like Arduino Gesture Controlled Robot, Dual Mode Robot, Arduino, and RF controlled Robot. The difference between previously posted robot projects and Arduino-based Bluetooth Controlled Car is, unlike others, that it does not require special types of control circuits. It can be controlled using any smartphone using the software. The best part of the project Arduino-based Bluetooth Controlled Car is you can wire it within an hour.…

The world is all about visualization. Mesmerizing illumination has been introduced which provides a different level of satisfaction for human eyes. Using multi-pattern LEDs lights in a cubical representation is our contribution to this global trend. The project; LED Cube 4x4x4 Circuit using AT89c2051 microcontroller to create several light patterns. The cube designed for specific use in science laboratories is much easier to assemble. Previously, we had posted an LED Matrix Display using Arduino. Circuit Description of LED Cube 4x4x4 Circuit using AT89C2051 You can see the entire circuit of…

Introduction to Offline UPS Circuit We all know that most electrical and electronic appliances are solely powered by the AC supply and the problem arises when the power is cut off in the middle or there is no power at all. In such cases, uninterrupted supplies are what we look out for. This is one of those uninterrupted power supply circuits. The fact that it provides an instant power supply from the batteries than standby generators that take long to operate, makes it more practical. To make the use of…

Here is a simple circuit using transistor called ‘Battery Status Indicator Circuit’ used to indicate two states of battery i.e. under charged and over charged. Previously, we had already posted similar circuit called Battery Voltage State Indicator using 741 used to indicate three states of battery i.e. charged, charging and discharge. Similarly, you can also design circuit which indicate status of battery in 10 different level. Circuit Description of Battery Status Indicator The circuit of Battery Status Indicator Capacitor is shown in figure 1. The main components of Battery State…

3.7V to 5V, 5.3V, and 6V Converter Circuit: The preferred voltage levels while working in most electronics projects lie between the value 5V to 6V. However, 3.6V-3.7V batteries are found abundantly in the market with a cheap price tag. So, we presented an economic solution to generate commonly used operating voltages i.e. 5V, 5.3V, and 6V using these cheap and easily available 3.6V and 3.7V batteries. Using two-three batteries of 3.6V (3.6*2=7.2V) and 3.7V (3.7*2=7.4V) doesn’t provide the desired voltage level and thus this project was essential. This DC-to-DC converter…

While flowing up the discussion on bestengineeringprojects.com, one of our readers ask about a dynamic microphone pre-amplifier. The dynamic microphone pre-amplifier circuit is a bit different than other microphone pre-amplifier circuits because it consists two-stage amplifier section. Thus, before going through the circuit description we would like to make clear the dynamic microphones. What is Dynamic Microphone? A dynamic microphone is a transducer that converts the sound signal into an electrical signal and works on the electromagnetic induction principle because it contains a moving coil. This microphone is also called…
