How to Generate Sine Wave using Arduino??

In this video we have taught about generation of sine wave using Arduino. The generated waveform is also simulated on proteus as well.

We also provide online training, help in technical assignments and do freelance projects based on Embedded Systems, Matlab, LabVIEW, Python, Data Science, Machine Learning, Linux etc.

one correction- 100 Hz will 0.01s which equals to 10ms. Thanks for uploading the video it was help full

Thanks for the video, I'm enjoying actually using some capacitors with my arduino and seeing how they interact with the design.

Thanks for info, But your code is erroring for me
Arduino: 1.8.13 (Windows 10), Board: "Arduino Uno"






















error: 'i' was not declared in this scope


t = (float)i/fs;

^

exit status 1

'i' was not declared in this scope



why is this error ..

127 its pwm value number 0-255? or only constant number in equation on your code sir? thanks

[krishnaks]

thank you for making such knowledge-based content.

Would it be possible to generate different frequencies depending on a key press and reading the array quicker or slower?

Can I produce a 1kHz sine wave in 0-5v?

[penscratch]

How would I go about generating an exactly 7.83 hz signal?

[thomascelik]

Hello, great video!
But why are u using the value 500 for the array? Does it have any reason?

[arunkarkare]

at time 4.51 in this video clip, it says "0.01milli seconds" should it be "0.01 seconds" please ?

[dshshajskj]

thanks for the informative video
can we generate a pure sine wave ac using arduino of varying frequency ?

[cyberwasp]

Sir, is there any where I can download your sketch from. I've tried to grab it from your video but it seems I missed something. I'm not getting a sinewave. Thank you

[dshshajskj]

can we ggenerate pure sine ac of 1kHz using arduino?

[jaywardhanpandit]

Nice Tutorial, Thanks sir,
I need some solution regarding this I have made this and tested it on My CRO, without its giving sinewave but when I connect 470uf as shown in video then it converts into almost Triangular wave. Pls how to resolve this.

[e.e.e.a]

i need to generate a sine signal from zero to 1Mhz
i coudn't create the code
Please if you can help

[satnaryan]

sir, how i can generate the sine using arduino nano 33 ble with DAC DFR0972 in oscilloscope, plz sir guide me

[fortundiamond]

I knew to use SPWM. However, it's a huge waste of transistors to generate a sine tone.

[laalaiwafa]

you can generate signal with any frequence with arduino mega or not ? because I need to generate a sine wave with 20 Khz.Please help me

[gingarrison]

Great thanks for this video from University of Nottingham

Why are you using capacitor, what is the use of it
