This library provides information of the IC’s along with their commercial nomenclatures and manufacturer
In this article, we are going to interface a Pulse Sensor with Arduino. The pulse sensor we are going to use is a plug and play heart rate sensor. This sensor is quite easy to use and operate. Place your finger on top of the sensor and it will sense the heartbeat by measuring the change
In this article, we are going to read the colors using the TCS230 color sensor (RGB Sensor) and Arduino Uno. The TCS 230 color sensor senses the color light by using the photodiodes. The sensor converts the readings from the photodiode into a square wave by using the light to frequency converter. The frequency of these
In this article, we will explain how to communicate to an external EEPROM from the AVR Atmega32 MCU using the I2C communication protocol. So let’s begin our tutorial on how to interface an EEPROM (AT24C16A) with AVR Atmega32. You will usually need an external EEPROM when your system has a certain set of user configurable
In this article, we are going to interface a Soil moisture sensor FC-28 with Arduino. This sensor measures the volumetric content of water inside the soil and gives us the moisture level as output. The sensor is equipped with both analog and digital output, so it can be used in both analog and digital mode.
Electrical connectors are used to join sections of a circuit. They play a crucial role in the overall working of an electrical component. Thousands of electrical connectors are available and each has its own unique features. They come in all sizes and shapes, from small IC to huge power connectors carrying high currents. With advancements
A “Drone” is basically an Unmanned Aerial Vehicle(UAV) Â – an aircraft without a human pilot aboard. In this article, we explore the different types of drones out there in the market – some of which are just concepts, while most others are already in action. “Drones” can be classified on a different basis – say
What is LCR Meter – an overview! LCR Meters are used to measure parameters of basic passive electronics components viz Resistor, Capacitor, and Inductor. LCR meters are available as desktop meters and handheld meters. Handheld meters are basically used for portability, use in the field and also by hobbyists to have a low-cost alternative with
myDevices – the company behind Cayenne – a drag and drop IoT project builder has announced its partnership with Arduino on August 9th 2016. With the partnership in place, Arduino’s large collection of open source boards are now accessible via the Cayenne visual editor. The importance of a visual IoT project builder is in acceleration
A GSM/GPRS Module is always needed to implement projects that involve SMS based or Web based controlling of devices. We have published lots of tutorials and projects using GSM and GPRS modules in CircuitsToday. This article is developed as a buyers guide for anyone interested in buying a GSM/GPRS module. There are a handful of
In this tutorial, we are going to build an LED Scroll Bar as shown in the image given below. The project is designed to flash Ten LED strips ( by giving different lighting patterns for each strip) with the help of a control board. We have created a simple GIF animation of the project to
Are you a beginner in Electronics wondering where to start? Well, we’ve all been there once like you, swimming on the shores not knowing where to go and wondering, “What’s the difference between resistance and capacitance?†or “Who is Georg Simon Ohm and why does he have a law?â€Â  In this article, we are reviewing
As the world grows to be digitally dependent, even doors can now be designed to be secure and safe. The digital version of the lock and key holds a lot of promising features. The digital door lock is securely placed with passwords. However, this may also attract unethical hackers, therefore, an extra layer of security
In this article, we are publishing a tutorial on how to interface seven segment LED display to Arduino. Seven segment displays are used in many embedded system and industrial applications where the range of outputs to be shown is known beforehand. Basic 1 digit seven segment display can show numbers from 0-9 and a few characters.
In this article, we are presenting a tutorial on how to interface LM35 and Arduino along with its program. Once we successfully interface arduino and lm35, we will go on to build a temperature display using arduino and a 16×2 LCD module which constantly monitors temperature around the measurement field/range of LM35 and displays the
In this tutorial, we are building an interesting application using Arduino and PIR Sensor. A Burglar Alarm – is basically an intruder alarm or an anti theft alarm. So this project is all about building an anti theft alarm or an intruder alarm using Arduino and PIR sensor. It is possible to enhance this project
In this article, we are going to learn how to interface/connect PIR Sensor or Passive Infrared Sensor to Arduino. We have written a tutorial on how to interface PIR sensor to 8051 previously in CircuitsToday! So a PIR sensor which is also known as Pyroelectric sensor or Passive Infrared Sensor is basically an electronic sensor
