Arduino is a popular open-source electronics platform that has revolutionized the world of hobbyist electronics and educational robotics. It’s a user-friendly tool for creating interactive electronic objects. Arduino’s boards are able to read inputs...
Pull-up and pull-down resistors are used to ensure that a digital input or output pin is in a known state, either high or low. This is important because many digital devices, such as microcontrollers...
What is an Arduino microcontroller? An Arduino microcontroller is a small, programmable device that can be used to control electronic devices. It is based on a simple hardware platform that is easy to learn...
VCOs are electronic circuits that generate periodic waveforms, such as sine, square, or triangle waves, whose frequency can be controlled by an input voltage. To describe the relationship between the control voltage and the...
RTC or Real-time clock is an electric device that tracks time which is useful for many embedded system projects that include Date&Time like time-based alarms, timer applications, calendars, scheduled operations, etc. An RTC module...
An overheat protection is used to prevent the self-destruction of devices due to excess heating resulting from prolonged use, overloading, cooling mechanism failure, other equipment issues, etc. This circuit shows a simple method of...
This is a simple stopwatch project using Arduino and an LCD display which can be used to measure the amount of time that elapses between the pressing of start and stop buttons. Refer: Arduino...
This project shows a simple method to obtain the current time on Arduino with the help of processing, it is very useful for many projects like timers, alarms, real-time operations, etc. Also, this method...
This project briefly describes the method to display live Arduino serial data on a webpage using processing code, server & client-side scripts. Here shows the basic working model to display real-time sensor reading which...
Here shows a method to upload and save the serial data from the Arduino to a web server. This can be used to send values from an Arduino to a web server via a...
