This is an interesting project in which we explore the power of an Arduino and Android to create a Surveillance device which uses Arduino and Ultra Sonic Sensor to broadcast the information to a mobile application (Android) using Bluetooth.
Safety and Security has been our primary concern since ages. Installing a security camera that has night mode…
There are several critical machines or expensive equipment which suffer damage due to vibrations. In such a case, a vibration sensor is required to find out whether the machine or equipment is producing vibrations or not. Identifying the object which is continuously vibrating is not a tricky job if the proper sensor is used to detect the vibration. There are several types of…
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…
RFID (short for Radio Frequency Identification) tagging is an ID system that uses electromagnetic waves in radio frequency to transfer data. A simple RFID system consists of just two components: the tag itself and a read/write device. The read/write device consists of a Radio Frequency module and an antenna that generates a high-frequency electromagnetic field while the tag…
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 MOSFET is a type of transistor that uses an electric field to control current flow, and is widely used in switching and amplification circuits. MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor, which has a gate. For simplicity, you can imagine this gate like a water tap. You rotate the tap counter-clockwise the water starts flowing out of the tap.…
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…
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…
