DIY Music players are fun to build, and we previously built a few music players using Arduino and a dedicated MP3 module. Now we are using the ESP32 speaker output to build an interesting audio player, in which you can add sound effects by just connecting an extra speaker to the ESP32. Here we will use LM386 and a speaker with ESP32 to play music files. The audio…
In this project we are going to work on an innovative arduino project idea, where we can count the paper currency notes and calculate their amount, by sensing the paper currency using Color Sensor and Arduino. TCS230 color sensor will be used for detecting the currency notes and, Arduino UNO for processing the data and showing the remaining balance on 16x2 LCD.…
A decimal counter is a chip designed to count the number of pulses or events that occur in digital circuits. These chips show the output in the decimal form or 1 to 99... form. So if we have a 12 bit counter, then it can count only 12 clock pulses or 12 events. These chips memorize the events and show the count of events at output port. The chip memorizes the event and shows…
Pulse Width Modulation (PWM) is a type of analog modulating technique in which the duration or width of the pulse changes in accordance with the time. It is a commonly used technique to produce a continuous pulse signal with a defined frequency and duty cycle. In short, PWM is about changing the width of a pulse while the frequency remains constant.

In this tutorial, we are going to talk about fuses. Back when I was in college and learning about all the cool things in electronics, I heard the term fuse in AVR for the first time, my initial thought on the topic was, oh! there is something inside the AVR that will blow if I did something wrong. Back then, there were not much resources available on the Internet…
Motion detection is a common application for intruder alarms, light switches, and other home and industrial automation applications. And there are several ways to do it. We have already used a PIR sensor for motion detection, it senses the change in ambient infrared energy caused when a warm body enters the monitored area.
In this tutorial, we…
GSM Modules are frequently used in IoT projects since it has the ability to send and receive data remotely. The GSM Modules doesn’t have much dependencies like the Wi-Fi modules. While other wireless modules such Wi-Fi or Zigbee have cons such as short range and cost, the GSM Module have the reliability, long range Since only one SIM card is required with valid plan. Though…
Scanning temperature at the entry gates of office, malls, shopping centers, etc. has become the “new normal” to tackle the current Covid19 pandemic. While it is possible to use a handheld IR thermometer to measure the temperature of each person entering the gate and note it down manually on a notebook, it is simply not the most effective way. We have already designed a…
Building an FM Transmitter and broadcasting our own signals on the air is really a fun project to do. Especially, with this circuit since it does not require you to wound your own inductor or use a trimmer and spend hours in tuning your circuit to make it work properly. In this project you will learn How an FM Transmitter Works and how you can build your own with…
In the field of DC-DC Converters, A single-ended primary-inductor converter or SEPIC converter is a type of converter that uses a boost type control topology to step up or step down the input voltage. After reading this, the first question that will come to your mind would be, is it like a glorified Classic Buck-Boost Converter? The answer is yes and no. A classic buck-…
This tutorial is the continuation of the previous tutorial Getting Started with ESP8266 (Part 1). So, to give a small recap, in our previous tutorial we introduced our self to the ESP module and learnt few basics about it. We also made a development board, using a FTDI Serial Adapter Module, which can be easily used to program the ESP module using both using AT commands and…
Text-to-speech (TTS) is a type of speech synthesis program that is used to produce a spoken sound version of the text, such as a document file or a Web page. TTS can make it easier for a visually impaired person to interpret computer display information or can be used to improve the comprehension of a text message. Other than that, it can be used to make your robot speak or…
