Welcome to this video on Arduino Tutorial for Beginners. This video about Analog Signal Output (PWM)

This video shows how to control speed of DC Motor with a little bit transistor knowledge. Arduino lacks a true analog output, so we need to use Pulse-width modulation (PWM) to simulate a variable DC supply voltage. PWM is a common procedure for supplying variable power levels to “slow” electrical devices such as resistive loads, LEDs, and DC motors. Pulse-width modulation (PWM) provides the ability to simulate varying levels of outputs.
Arduino Uno has 6 PWM pins: Digital I/O pins 3, 5, 6, 9,10, and 11
Make Fading led and Control RGB led

Code :

analogWrite(_pin,value)
_pin is the PWM pins (has tilde before) and value from 0 to 255

Arduino is an open-source hardware platform based on an Atmel AVR 8-bit microcontroller and a C++ based IDE. Arduino is the go-to gear for artists, hobbyists, students, and anyone with a gadgetry dream. Arduino microcontrollers are programmed using the Arduino IDE (Integrated Development Environment). Arduino IDE Can be downloaded for free from http://arduino.cc/en/Main/Software
Arduino programs, called “sketches”, are written in a programming language similar to C and C++. Many sensors and other hardware devices come with prewritten software – look on-line for sample code, libraries (of functions), and tutorials. Learn the Arduino platform and programming language to create robots, interactive art displays, electronic gadgets and much more.
