FADING LED ON BREADBOARD WITH PWM - Arduino tutorial #3

In this Arduino for beginners tutorial I teach you how to fade an LED using the PWM (Pulse Width Modulation) technique. Code arduino-tutorials.net/tutoria...
The resistor calculator: www.allaboutcircuits.com/tool...
PWM (Pulse Width Modulation) is a technique which can be used to fade a LED. In this tutorial I explain with some examples how PWM works. We end with creating the code to actually fade a LED on a breadboard.
The Arduino for beginners tutorials series guides you through the world of Arduino. A video is around 10 minutes and shows you step-by-step how to build the circuit and write the code. The website contains the course material, circuit diagram, Arduino code and shopping list of all the components used in the tutorial.

am impress new to this and learning fast

[@BasonTech]

Great to hear! 😃

[@kwabzmahle9016]

Thanks for the helpful videos.
On the Arduino IDE, why does the LED only fade when I type 'analogWrite' and not when I type 'digitalWrite'?

[@BasonTech]

Hi, digitalWrite() can only write 2 values: HIGH and LOW. Therefore the LED can be On or Off. analogWrite() is able to write 1024 different values so the LED can have 1024 different brightness levels which we se as fading.

[@kwabzmahle9016]

@@BasonTech Wow. Thanks.

[@reshairo]

Im new to arduino & for your channel. Greate tutorial. Still watching from #1.
I have 1 question, in the beginning you said in digital pins can deliver 1 & 0 only then how led dimmer works with digital pins (im assuming dimming is analog). Again i want to remind you im new to arduino 😉

[@BasonTech]

Hi, interesting question! A LED dimmer can work multiple ways see blog.visual.electro-matic.com/how-do-led-dimmers-work But if I understand correctly you make LED blink very fast and that simulates the dimming 😃

[@reshairo]

@@BasonTech noted with many thanks

[@prithvimellacheruvu6378]

Hey, I wanna do the same experiment but using 2 leds. When one fades out, the other must fade in. Any tips wrt code?

[@BasonTech]

With this tutorial you should be able to make this 😃 This trick is to invert the value of the 2nd LED with the 1st one

[@kiwinesss]

Done ... I have to do more with the "for" function. I didn't really quite get it completely.

[@BasonTech]

For loops are not the easiest part of programming. However what could help is to make some on your own. For example:
- a loop that goes from 0 to 10
- a loop that goes from 5 to 10
- a loop that goes from 5 to -5
- a loop that goes from 2, 4, 6, till 10
- a loop that goes from 1, 5, 10 till 20
Good luck! 😃

[@kiwinesss]

@@BasonTech Super idea, thanks, I will do it now.

[@nadenglish3811]

How to make it stay on after it glows gradually, while keeping in mind it has to gradually fade out when the LDR value is up

[@BasonTech]

On what part are you getting stuck?

[@raymondmichael4987]

How can we avoid those delays!? As they stalls the mc

[@BasonTech]

You can using millis() This is an advanced topic but I describe it in arduino-tutorials.net/project/digital-arduino-clock
