Build a Battery Internal Resistance Meter with Arduino and Atmel ATtiny85 IC In an ideal scenario, a battery should have zero internal resistance. But batteries are not made perfect and the electrodes are not 100% conductive, which creates a small resistance within the battery called internal resistance. Practically batteries will always have some internal resistance. On paper, the value of the resistance will appear low around 0.1Ω for… |

Interfacing TM1637 4 Digit Seven Segment Display Module with Arduino If you are thinking about building your next project around a 4-digit seven-segment display, you need at least 12 connecting pins to drive all the segments properly, that is most of the pins for a microcontroller like Arduino. The workaround for this problem comes in the form of an IC, and as the title of the project suggests it's called TM1673 LED Drive Control. So… |

Interfacing WS2812B Neopixel LED Strip with Arduino When you require a dynamic lighting solution, LED strips are a great choice. They may be mounted almost anywhere, available in a variety of colours, and require very little maintenance. Finding another lighting system that offers as much value and style would be challenging. And even this standard is raised to a completely new level by… |

Interfacing MAX7219 LED Dot Matrix Display with Arduino When it comes to adding a display to your next project there are many options to choose from like OLED, 16x2 LCD, Seven Segment, and E-Paper Display. But there exists another type of display that I feel is mostly ignored due to the lack of coverage by enthusiasts and hobbyists on the internet. So in this article, we decided to shed some light on this cheap and easy-… |

Interfacing RCWL 0516 Microwave Radar Sensor with Arduino Proximity sensing is a common application for intruder alarms, light switches, and other home and industrial automation applications. There are multiple methods of proximity detection used in the electronics industry. The most common method is to use the PIR sensor, which senses the change in ambient infrared radiation caused by a warm body… |

How Does the GP2Y1014AU0F Dust Sensor Work and How to Interface it with Arduino When we are talking about air pollution, dust and smoke are one of the many reasons for air pollution. Not only that, in recent years, due to climate change, wildfires have become more frequent. A recent report from the National Interagency Fire Center (NIFC) reported a total of 58,733 wildfires across the US that had burned more than 7.13 million acres in 2021 alone… |

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 … |
