Nice project 👍

[@TheJavaSync]

Very nice web, hope I can build It soon, thank You :)

[@jeanyves5380]

There are specific ships including micro-contrôlers to achieve this.
They will give you true waves, tricky things and even sometime will include powerfull output buffer for hight level and current output signal.

[@gartmorn]

Is this still to be linked as I can't find it on circuitdigest?

[@thanosxe.8464]

Can it output in AC ?

[@yassinegaming9398]

Sir can you make a frequency receiver exactly like this
But receives frequencies wirelessly and gives the value of the existing frequency?

[@e-teslaacademy1031]

Plz make video on IOT based induction motor speed control using esp6628 ( nodemcu ) sine wave inverter

[@acqurius-gx8lr]

how to keep fix duty cycle of 50%.as when you change frequency duty. cycle is also varying

[@tonyvarghese75]

Please give the circuit diagram and code

[@askinc102]

what is the max switching frequency?

[@69iqtutorial]

U probably want to make a tesla coil?

[@nalinux]

With my Robodyne encoder, I had to add a pull-up resistor for the switch, and swap A and B output.
Funny fact, the display goes bellow 0 Hz, aka -6 Hz :)
I suppose this can be fixed easily in the code, I didn't check yet.
It would be nice to also modify it to have frequency output between 0 and 1 Hz.
There's also "const int POT_pin = A2; ", which is not used.

[@Piccodon]

Nice!
Can the resolution be increased to say 0.01Hz, or less?

[@owendavidmalicsi5900]

that's like 1 in 100 seconds right? perhaps u can do without a function generator and just use the arduino with delay for that

[@chbonnici]

Can you give us a link to buy the three pins where you hook the oscilloscope. I cannot find them anywhere. Thank you great video.

[@Circuitdigest]

I not sure to which pin you are referring to

[@chbonnici]

Thank you for answering. The three pins in video at time 0.23secs where you connected the oscilloscope probe. I want to buy some of these pins from AliExpress but cannot find them.

[@innamohammad254]

can it reach at least 1ghz with out any module?

[@kahe7436]

Both the circuit and code were faulty

[@SpeccyMan]

Someone needs to learn how to use the trigger on their scope.

[@rumahhafidzahbekasi1354]

oof

[@adnan_oday]

Hi, once i upload the code , this massage ( InitTimersSafe was not declared)

[@mypkamax]

I can't hear the waveform...

[@Tofupancho]

It sounds like this- woowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoowoo

[@bahrilnugroho1474]

Why you said , "its not "proper sine waves"...i need explanation

[@basicvai3854]

Sinewave follows the sine or cosine formula. But this sinewave is generated by rough enveloping using a crude Low pass filter. Hence this is unlikely to follow the simple harmonic motion.

[@KishanRandika]

Hello , I create this circuit . But it canno't work 🥲
