Fire safety alarms are crucial in both residential and industrial environments. Early fire detection can prevent significant damage and save lives. Flame sensors offer one of the most efficient ...

This Arduino-based night security light can protect your home/office from thieves/intruders at night. The light glows when movement is detected in front of the PIR sensor. Simultaneously, a piezo ...

USB Powerbank have a nasty habit of shutting off if you don't use enough power. This might be fine if you are charging a phone, but if you are using them to power a small arduino or led project, it is ...

While designing an internet of things (IoT) project that also required a long radio-frequency link, it occurred to me that there are pre-wired modules already built to do that. In fact, not only do ...

LED Blinking is a very common and almost first program for every embedded learner or beginner. In which we blink an LED with some delay. So today we are here with the same project, but here we will ...

In this tutorial, we will develop a 5V variable voltage source from Arduino Uno. For that, we are going to use ADC (Analog to Digital Conversion) and PWM (Pulse Width Modulation) features. This ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...
