Arduino Lesson 7 - Analog Write

In this session we learn how to create analog voltage levels using pulse width modulation. Understanding PWM is not required to be able to do analog writes, because the Arduino software makes it really easy for us, but the theory is useful to understand and can help you create calculated voltage levels.

Hands down the best arduino tutorials I found on YT. No useless chatter, no pointlessly childish or overcomplicated explanations, everything is concise and easy to follow. Cheers!

[anshumanbharadwaj]

after searching watching almost 100 vids I found one useful

[sanpol]

The best explanation I saw about pwm so far. 👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻

[pranavshankar]

these series are by far the best tutorials i've ever seen and i love them. you need to get a million more subscribers for such a work like this

[einradbaer]

This is the most useful videoseries on arduino I have ever watched. Thanks!

[Frightline]

I learn more from you than anyone.Please keep the videoas coming please.

[minskie]

You, Sir, are an excellent teacher for learning Arduino! I thank you for your channel!

[Minoclassic]

Too good ! You should keep doing videos like that 💯🔥

[SchwanaCARDHUT]

Thank You very very much your tutorial was so much comprehensibles .
Merci beaucoup votre tutoriel était tellement compréhensibles.

[ej]

Wow, your handwriting and explanation is amazing!

[fazilates]

Legendary explanation. Thanks! @Benduino

[mrd]

Best explanation of Analog Write! thank you so much!!!!

[yadwindersingh]

Sir you are
You explain this very well....
One of the best video on YouTube about Arduino I learned something new today. Please also make a video on else statement. Great thanks
Love from India 💓💖

For this to work properly, is it dependent on the natural capacitance of the wires that the PWM signal is being transmitted on, so that those wires more or less "average out" the PWM signal into the desired fractional voltage? are there cases where we'd want to use a capacitor to smooth out the PWM signal for us before any downstream components receive the PWM signal?

[kelcamer]

Awesome explanation! Since this pwm wave is just an average of the on and off voltage duty cycles, wouldn't that introduce extra noise into the circuit? Is there really no way of giving it an exact voltage without using a buck base converter?

[ZacharyPittman]

is the voltage actually averaged in PWM or is it a visual thing for an LED? Like, do we only see half the brightness if running at 2.5v but it is actually 5v half the time?

[manishpingale]

thank you, sir
You Helped me a lot
thank god I found this video

[yashiqpm]

I am searching for tutorial like this.

can you make a tutorial on nodemcu that board is used to make wifi projects

[pasumarthiashik]

so it means these pins are giving out analog output using pwm technology ??

[ahmetkutan]

Thank you man you saved my life XD i mean my test
