How Does the TCS3200 Color Sensor Work and how to Interface it with Arduino? A color sensor is a simple, and easy-to-use device that can be used to identify the color of an object and after detecting the color, appropriate action can be triggered. This type of sensor provides easy solutions for sorting and packaging in an industrial environment while expensive sensors are used in industries, the economical ones such as TCS3200 can be used for… |

How Does the Pulse Sensor Work and how to Interface it with Arduino? In one of our basic projects, we have shown you how you can interface a MAX30102 Pulse Oximeter and Heart Rates Sensor With Arduino, but one of the major problems with that sensor is its inconsistency, and lack of support for Arduino IDE which is why in this article we thought to use a simple pulse sensor to measure the heartbeat. This pulse sensor is a well-designed… |

Yet Another Arduino Digital Clock, but It’s Unique and You Will Need It I know making a clock sounds a little irrelevant, especially nowadays because we all have smartphones and no one is going to use or look into the clock for time, but it is good when you are doing some work or during the workout. So, I decided to make one Arduino digital clock for my room. While searching for the clock model, I got thousands of designs but most of them were… |

Interfacing NTC Thermistor with Arduino Thermistors are simple, inexpensive, and accurate components that make it easy to get temperature data for your projects. Thermistors or THERMally sensitive resISTORs are variable resistors, whose resistance will be changed with the temperature. This feature enables us to read the temperature or change in temperature by… |

How not to Build a POV Display Using WS2812B Neopixel LEDs and ESP8266 For one of our projects at circuit digest, we wanted to build a Persistence of Vision Display or POV display with WS2812B LEDs. While making the project, our only focus was on how we could make it simpler along with less hardware. As a result, we chose some simple WS2812B RGB LEDs and an ESP8266-01 as the brains for this project because they are lightweight … |

How Does a LM35 Temperature Sensor Work and how to Interface it with Arduino? If you are looking for an inexpensive, accurate, easy-to-use temperature sensor, then LM35 is an excellent choice. It has an accuracy of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C temperature range. It does not require any external trimming, although the main drawback of this sensor is that it outputs data in analog format, making it … |

Interfacing Hall Effect Sensor Module with Arduino A Hall effect sensor or Hall sensor is a magnetic non-contact sensor that generates an electrical signal proportional to the magnetic field applied to it. Hall effect sensors are widely used in industrial applications like current-sensing, position detection, and contactless switching. They are basically like a small reed switch, and when a magnetic field is around, the… |

Interfacing 16x2 LCD with Arduino In this digital age, we come across LCDs all around us from simple calculators to smartphones, computers and television sets, etc. The LCDs use liquid crystals to produce images or texts and are divided into different categories based on different criteria like type of manufacturing, monochrome or colour, and weather Graphical or character LCD. In this tutorial, we… |

DIY 18650 Li-Ion Battery Capacity and Discharge Testing Meter using Arduino There are multiple Lithium batteries available in the market with larger options in capacity. However, as we all know lithium batteries are need to be charged, discharged, or even stored in a particular manner to extend their life. In this project, we will explore a circuit that will discharge the battery fully and provide the result of how much capacity the battery has.… |

Different Ways to Power Your Arduino Boards We use Arduino boards in many of our projects. Most of the time we will power it through the USB port. But, that’s not the only way to power an Arduino. In this article we will learn about the four different ways to power an Arduino UNO board. While making any projects, knowing these techniques will be handy in instances when flexibility with regards to the power supply is required. 1… |
