The millis() function is one of the most powerful functions of the Arduino library. This function returns the number of milliseconds the current sketch has been running since the last reset. At first, you might be thinking, well that’s not very useful! But consider how you tell time during the day. Effectively, you look at how many minutes have elapsed since midnight. That’s the idea behind millis()! Instea ...

What language is Arduino? Arduino is not a language, Its an electronic board, built with several other components to perform different programmed tasks. Think of it as mini-computer but we don't have keyboard, lcd attached with it, still it has its own ram, cpu processing power, rom. Input / Outputs etc. Think of getting done something like turn on outside lights when the sun-light level get low. We can pro ...

It should come as no surprise that the modern businesses heavily rely on technology for much of their daily endeavors. Technology is known to increase efficiency and productivity, when it is utilized properly. Thus, this article will better explain exactly how tech innovations can transform the future of your business, and it is in your best interest to adopt the following factors into your company operatio ...

In this article we are going to see about what is PCB board and some types of PCB board. A PRINTED CIRCUIT BOARD (PCB) mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet  layers  of  a non-  conductive substrate. Components are genera ...

Accessing local USB ports and devices in VirtualBox VirtualBox 6.0 allows you to take advantage of USB passthrough support to access locally attached peripheral devices. Here is a step-by-step guide that illustrates using USB in VirtualBox. Optionally install the free VirtualBox Extension Pack. This extension offers the faster speed afforded by USB 3.0 support. After installation, start your virtual machine ...

Introduction: The use of LED based electronics has significantly increased in the past few years. They have proven to be more efficient and nearly 5 times cheaper than normal incandescent units. But with their use came one downside: heat. Some devices tend to use a number of LEDs that remain on for a long period of time and so can overheat. The LEDs are usually mounted on PCBs and can therefore cause signif ...

This wireless LCD display shows information sent from a smartphone. The user can send text messages with up to 32 alphanumeric characters to the LCD within Bluetooth range of about 10 metres. This project can be extended and implemented in many ways for: 1. Educational organisations (schools and colleges). To inform any changes in the timetable or important information 2. Hospitals. To inform a doctor’s nam ...

Lichee Dan combines two beautiful worlds together: Open source and Artificial Intelligence into one single platform. Lichee Dan which is also officially named the Sipeed M1 series is an excellent open source AI development kit made by the team behind the LicheePi boards. They aim to promote AI-related development and education. Unlike the conventional C or C++ seen in most hardware boards, the Sipeed M1 int ...

PCB Quality Control Almost every electronic device now a days is powered by one or more printed circuit boards (PCBs). Simply, we can say PCBs are the heart of electronic devices. Hence, the quality and reliability of PCB are directly correlated with the quality and reliability of the electronic device. For example, flaws in defining characteristics such as size and power consumption not only directly impac ...

The power saving mode here is what sets this Instructable apart from other examples showing day of the week, month, day of the month, time, humidity, and temperature. It is this capability that allows this project to be run from a battery, without the requirement for a "wall wart". I had posted an earlier Instructable, Humidity and Temperature LCD Display with Power Saving Mode: Minimal parts, Fun, Quick, a ...

arduino uno pinout pdf Arduino Uno Pinout Guide In our last two posts, we focused on the software aspects of the Arduino. We saw that Arduino boards are programmed using a language derived from C and C++ in Arduino's Integrated Development Environment  (IDE) and learned a few basic debugging methods. In this post, we'll be taking a closer look at the Arduino hardware, and more specifically, the Arduino Uno ...

The June 23, 1988 issue of EDN included a Maxim Design News insert where we asked "Who in their right mind would choose a computer interface standard that uses ±12V supplies, requires expensive connectors, works over a limited distance, is error prone, difficult to network, and has no current loop isolation?" Yet, here we are 28 years later and the classic interface lives on, particularly in industrial appl ...
