Do you face such situations when you leave your reading lights, table fans or soldering irons without switching them off and later realize that they were on for too many hours which subsequently jumps off your electricity bills? Well, if you have such a problem of forgetting things which probably most of you would have …

Introduction As you probably know, Iran has dry weather, and there is a lack of water in my country. Sometimes, especially in the summer, it can be seen that the government cuts the water. So most of the apartments have a water tank. There is a 1500 litre tank in our apartment which provides water. …
In this IoT based project, I have made Home Automation with Blynk and NodeMCU control relay module with real-time feedback. In the Manual Mode, this relay module can be controlled from Mobile or smartphone and, Manual switch. In Auto Mode, this smart relay also can sense the room temperature and sunlight to turn on and …

When I build my previous mini oscilloscope I wanted to see how well I could make my smallest ARM microcontroller a STM32F030 (F030) perform, and it did a nice job. In one of the comments it was suggested that a “Blue Pill” with a STM32F103 (F103) might be better, smaller than the development board with …
So in this project we are going to combine the MU vision sensor with a Kitronik Zip Tile. We will use the MU vision sensor to recognise colours and get the Zip Tile to show it to us. We are going to use some of the techniques that we have used before. Mainly how to …

Before I continue my serie of MU vision sensor instructables for the Micro:bit, I need to make this instructable for the Kitronik Zip Tile, since I am going to use it. The Kitronik Zip Tile, I will just call it Zip from now on, is an 8×8 neopixel matrix, that can be run fairly easy …
Hall sensors works on the principle of Hall Effect proposed by Edwin Hall in 1869. The statement proposed says, “The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.” So, what could …

We created a standalone face recognition system for access control. Users enroll in the system with the push of a button and can then log in with a different button. Face recognition uses an eigenface method. Initial testing indicates an 88% successful login rate with no false positives. There are currently commercially available systems for …
