Arduino – Inter-Integrated Circuit
Inter-integrated circuit (I2C) is a system for serial data exchange between the microcontrollers and specialized integrated circuits of a new generation. It is used when the distance between them is…
Arduino – Communication
Hundreds of communication protocols have been defined to achieve this data exchange. Each protocol can be categorized into one of the two categories: parallel or serial. Parallel Communication Parallel connection…
Arduino – Interrupts
Interrupts stop the current work of Arduino such that some other work can be done. Suppose you are sitting at home, chatting with someone. Suddenly the telephone rings. You stop…
Arduino – Random Numbers
To generate random numbers, you can use Arduino random number functions. We have two functions − randomSeed(seed)random() randomSeed (seed) The function randomSeed(seed) resets Arduino’s pseudorandom number generator. Although the distribution…
Arduino – Pulse Width Modulation
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…
Arduino – Due & Zero
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…
Arduino – Trigonometric Functions
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…
Arduino – Math Library
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…
Arduino – Character Functions
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…
