Compound operators in Arduino work just like in C, and they help save you some writing time, and also reduce the number of lines in your code. As the name seems to suggest, compound operators combine multiple operators.The following table lists the compound operators in Arduino.Assume that a and b ... Read More

In order to convert variables from one type to another, you use the CAST operator. The syntax is −(type) var;Where var is the variable to be casted, and type is the new type to which you wish to convert it. For example, if you have a variable of type float, ... Read More

A hardware serial, as the name suggests, denotes that a dedicated piece of hardware (UART) enables Serial communication. In Arduino Uno, for instance, pins 0 and 1 have UART support, and they are connected to the USB via a USB-to-UART converter. That facilitates communication between your computer/laptop and the Arduino. ... Read More

You can define a class in Arduino just like in C, with public and private variables and methods.The example below demonstrates the definition of a Student class, which has the constructor, two methods (add_science_marks and get_roll_no) and 3 private variables, _division, _roll_no and _science_marks.Exampleclass Student {    public:     ...

I2C stands for Inter-Integrated Circuit. It is a popular communication protocol used by several peripherals like accelerometer and gyroscopes, OLED Displays, etc. Arduino refers to I2C as Wire, which is a shorter form of the term Atmel uses (Two Wire Interface or TWI). Here are some salient features of I2C ... Read More
