Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Passive Infrared (PIR) sensors are electronic devices that detect motion by sensing infrared radiation emitted by objects. Every object with a temperature above absolute zero emits infrared radiation.

Halloween is coming up faster than you think: time to dust off the gravestones and the zombie lawn decorations! This year you may want to add a little something extra to give the trick-or-treaters a ...

You would have probably read about the SONAR that’s used in ships. By taking the same concept into a small form factor we get a distance sensor. This sensor is available in multiple variants and I’ll ...

Now lets get back to our TMC2208 stepper driver module understand its basics and learn how to use it with an Arduino UNO board. One of the standout features of the TMC2208 is its ability to operate ...

It’s really hard to overstate how awesome ESP8266 development boards like the Wemos D1 Mini really are. For literally a couple of dollars you can get a decently powerful Wi-Fi enabled microcontroller ...
