I cover the basics of PWM and show you how to cheaply build a PWM circuit that can dim LEDs, control the speed of a motor, or control the power going to pretty much anything you want!

In this video, I introduce the concept of PWM and provide a few examples of how PWM works. -~-~~-~~~-~~-~- Please watch: "ARM Microcontroller Tutorial - GPIO Push Button Input - Software Debouncing Part 1" https://www.youtube.com/watch?v=mlRM2UfrX4A -~-~~-~~~-~~-~-

Pulse Width Modulation is a intuitive way to control voltage digitally. It pulses voltage very rapidly in such a way that it can reduce voltage to your desired voltage. The main parts of a PWM signal are is period and its duty cycle. The duty cycle is what determines its voltage. the period length will determine if it works with the device you plan to use it with, generally the higher the frequency, the more compatible the signal will be for your device.
http://blog.makezine.com/?p=98982 Another clever trick from the world of electronics - Pulse Width Modulation is a simple method for controlling analog devices via a digital signal. It's also an efficient way to drive motors, lamps, LEDs & more.
Explicar como funciona o PWM (pulse width modulation) e algumas de suas aplicações como no controle de velocidade de motores DC (CC ou corrente contínua), servo motor, acionamento de TRIAC, controle de temperatura acionando cooler e variando sua velocidade, fontes chaveadas para leds e outros. Falamos também da aplicação em Arduino e eletrônica, utilizando microcontrolares PIC ou 8051 e usando o sinal de saída dos pinos PWM para controlar periféricos através de drivers. É possível fazer um PWM até mesmo utilizando um 555 e circuitos de funcionamento simples. Em se tratando de eletrônica, controlar motores DC e realizar a variação da velocidade ou o brilo de LEDS é uma das tarefes mais utilizadas com fins didáticos.

Both have their own advantages and disadvantages but none is perfect in all situations. Music: Killing Time, Kevin MacLeod (incompetech.com) You want to support my videos?

There's a place in my heart where you used to be
There's a pain, deep inside, don't want the world to see
Nothing, but emptiness, once there was your caress
I was touched by your naked flame
Now, it was hard sometimes, those things that we went through
But believe me when I'd say, I would never mean to hurt you
I hold the memory of holding you next to me
In my arms like a naked flame
Think it over before you break my heart
Think it over before the crying starts
Then we can say goodbye to the tears
I should have known that this time was a coming
But if you ever need me, I'll come a running home to you
There's a place in my dreams where we used to meet
But there's no one around now, it's just an empty street
I hold the memory of holding you close to me
In my arms, like a naked flame
