Getting started with Arduino
What do we need? So we need an Arduino board that we can program on. There are various types of Arduino boards from simple one to complex one. Check out all available boards at https://store.arduino.cc/usa/. Don't get confused with all those boards. We will start with a simple board called the Arduino Uno. It is … Continue reading Getting started with Arduino
What is Arduino?
If you look at Arduino's official website, it says "Arduino is an open-source electronics platform based on easy-to-use hardware and software". Don't be confused . I will explain. Let's understand each term in above definition. What is hardware? Hardware is the physical, tangible parts or components of a computer, such as the cabinet, central processing … Continue reading What is Arduino?
