Pulse Width Modulation or PWM is a common technique used to vary the width of the pulses in a pulse-train. PWM has many applications such as controlling servos and speed…

The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board based on a 32-bit ARM core microcontroller. Important features…

You need to use Trigonometry practically like calculating the distance for moving object or angular speed. Arduino provides traditional trigonometric functions (sin, cos, tan, asin, acos, atan) that can be…

The Arduino Math library (math.h) includes a number of useful mathematical functions for manipulating floating-point numbers. Library Macros Following are the macros defined in the header math.h −Given below is…

All data is entered into computers as characters, which includes letters, digits and various special symbols. In this section, we discuss the capabilities of C++ for examining and manipulating individual…

In this chapter, we will learn some advanced Input and Output Functions. analogReference() Function Configures the reference voltage used for analog input (i.e. the value used as the top of…

The pins on the Arduino board can be configured as either inputs or outputs. We will explain the functioning of the pins in those modes. It is important to note…

Arrays with two dimensions (i.e., subscripts) often represent tables of values consisting of information arranged in rows and columns. Following are the key features of multidimensional arrays − To identify…

To pass an array argument to a function, specify the name of the array without any brackets. For example, if an array hourlyTemperatures has been declared as the function, the call passes…

An Array in Arduino is a consecutive group of memory locations that are of the same type. To refer to a particular location or element in the array, we specify…
