Overview Have you ever been sitting in your room, and want to turn things like light bulbs or fans on and off, but you don’t feel like doing it? Or you want to turn the cooling system on before arriving home, so it would be pleasantly cool by the time you’ve arrived? So, if you like controlling electrical devices of your home remotely through your cell phone, this tutorial can be so useful for you. There is an application called “Google Assistant” installed on most smartphones. You can use Google ...

Overview Have you ever wanted to use 2 sensors with the same I2C address at the same time, not knowing what to do? Faced some serious challenges in doing that? In a lot of projects, we have used different modules and sensors that support I2C communication protocol. Sometimes, we have interfaced some I2C modules with a microcontroller in our projects. If they all have different I2C addresses, we could easily interface them, facing no serious trouble. But, if 2 or more of the modules had the same I2C address...

Overview In this article, you will learn how to control DC, Stepper, and servo motors by Arduino and L293D.
