Have you ever wanted to add some cool lighting effects to your electronic circuits or spice up your home decor with a mesmerizing light show? Well, a circular LED chaser might just be what you're looking for! And the good news is that it's easy to build one using the 74HC595 integrated circuit. So in this article, we will show you how to build a stunning circular LED…

Today, we are going to Interface 2.4 inch TFT LCD Shield with Arduino. By using this color TFT LCD shield we can show characters, strings, blocks, images etc on the color TFT LCD. And we can use this TFT Shield in many applications like:  Security System, Home Automation, Games etc.

Interfacing TFT LCD with Arduino is very easy. We only need to…

In the previous tutorial, we demonstrated detailed design of Boost Converter using MC34063, where a 3.7V to 5V boost converter was designed. Here we see how to convert 12V to 5V. As we know that exact 5V batteries are not always available, and sometimes we need higher voltage and lower voltage at the same time to drive different parts of circuit, so we use higher voltage (…

Heart rate, body temperature and blood pressure monitoring are very important parameters of human body. Doctors use various kind of medical apparatus like thermometer for checking fever or body temperature, BP monitor for blood pressure measurement and heart rate monitor for heart rate measurement. In this project, we have built an Arduino based heartbeat monitor which…

When it comes to giving your projects wireless capabilities, A 433MHz RF Module is the most common and easiest way to get things done. A 433MHz RF module uses the ASK modulation methods to transmit and receive data between two devices. It is widely used in many applications, including remote control systems, wireless security systems, and telemetry systems. So…

LEDs are commonly used in electronic circuits as they consume less power, are easy to use, and have a long lifespan. In this tutorial, we will learn how to build an LED ON and OFF circuit using 555 timer IC and BC557.

Before we get started, let's understand the components we will be using in this circuit.

We all are quite familiar with Electronic Voting Machines, where your vote gets registered electronically and you don’t need to use ballot paper to vote in election. Today security is a major concern and it also needs to be ensured that someone can’t vote twice, so this problem can be solved by introducing Finger Print Based Voting, where a person can be authorized based on…

AND logic gate is a digital logic gate, designed for arithmetic and logical operations, every electronic student must have studied this gate is his/her career. This gate is mainly used in applications where there is a need for mathematical calculations. So in calculators, computers and manly digital applications use this gate. Here we are going to use IC 74LS09 for…

Avengers Assemble! Who does not like the Marvel Cinematic Universe? So, today we have a great project for you people that is a Wi-Fi-controlled Ironman mask. These days evolution and adaptation of 3D printed tools have seen a great increment for a plethora of purposes. We brought the use of a cool 3D printed design to make it into an Ironman mask that can be controlled over…

The ESP32 is a powerful, low-cost microcontroller that is widely used in the development of IoT projects. It is popular for its high processing power, low energy consumption, and built-in Wi-Fi and Bluetooth capabilities.

Bluetooth Classic is a wireless communication protocol that is used for connecting devices over short distances.…

In this short tutorial, we will show you how you can build yourself a transistor-driven color-changing RGB LED lights. The building process is simple and requires only a few transistors, capacitors and resistors to build it. The lighting system built in this way is not only efficient but cost effective but it can also create stunning color effects that can transform…

Thermometers are useful apparatus that have been used for a long time for temperature measurement. In this project, we have made an Arduino based digital thermometer to display the current ambient temperature on a 16x2 LCD unit in real time. It can be deployed in houses, offices, industries, etc., to measure the temperature. We can divide this Arduino…
