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 ...

In this project, we are going to build a Transistor Based Simple Soil Moisture Detector Circuit. In this circuit, we have used an NPN transistor to detect soil moisture. This is very simple and ...

Water tank overflow is a common problem which leads to the wastage of water. Though there are many solutions, like ball valves which automatically stop water flow once the tank gets full, electronics ...

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 ...
