Arduino Tutorial for Beginners 11 - Analog Signal Output (PWM) (Control Speed of DC Motor)

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 This video is created by Anh Quân Tống - https://w ... #ProgrammingKnowledge #analog_input #Arduino #Tutorial #Learning #Board_Description #Variables_and_Constants #Advanced_I/O_Function #Inter_Integrated_Circuit #Introduction_to_Arduino 20190409 Szu8-_g1dAk
