Arduino Based Digital Thermometer using MAX30205 Human Body Temperature Sensor For medical or clinical applications, measuring human body temperature is an important parameter to determine the health condition of any individual. However, there are lots of ways to sense temperature but not everything has the accuracy to meet the clinical thermometry specifications. The MAX30205 temperature sensor is specifically designed for this application. Do note… |

IR Remote Decoder using Arduino IR (Infrared) communication is simple, low-cost, and widely used wireless communication technology. IR light is somewhat similar to the visible light, except that the wavelength is slightly longer. This property of IR makes it undetectable to the human eye and perfect for wireless communication. There are lot of applications where you need to decode… |

Simple Ultrasonic Acoustic Levitation using Arduino and HCSR04 Ultrasonic Sensor It is very exciting to see something floating in the air or free space that is exactly what an anti-gravity project is about. The object (basically a small piece of paper or thermocol) is placed between two ultrasonic transducers which generate acoustic sound waves. The object floats in the air because of these waves which seem to be of anti-gravity. This is not only a cool… |

Digital Audio Volume Control Circuit using PT2258 IC and Arduino A potentiometer is a mechanical device using which one can set the resistance according to the desired value, thus changing the current passing through it. There exist many applications for a potentiometer, but mostly, a potentiometer is used as a volume controller for audio amplifiers. The digital volume control circuit is an electronic circuit that accurately adjusts… |

Arduino to Arduino Bluetooth Communication using Master Slave Configuration HC-05 Bluetooth Modules are the go-to Bluetooth modules for any Arduino project! It’s easy to hook up and code in the Arduino IDE. In most projects, we usually connect to HC05 to an Arduino and use it to wirelessly communicate with another smart device like a mobile phone. This is fairly simple and we have built many interesting projects with it like Bluetooth Controlled… |

Designing a True RMS to DC Converter using IC AD736 A True-RMS or TRMS is a type of converter which converts RMS value to equivalent DC value. Here in this tutorial, we will learn about true RMS to DC converter, how it works and how measurement methods can affect displayed results. What is RMS?RMS is the abbreviation of Root Mean Square. By definition, for alternating electric current, the RMS value… |

Fastest Arduino RC Car using Coreless DC Motors and nRF24L01 RF module RC cars are always fun to play with, I am personally a big fan of these remote-controlled Cars and have played (still do) with them extensively. Most of these cars today provide a huge torque to handle rough terrains, but there is something that was always lagging, its Speed!!.. So, in this project, we will build a totally different type of RC car… |
