Arduino - Simple Waveform Generator (Simulation)

Waveform Generator:
Diese Schaltung ist ein 8-Bit-DAC bekannt auch als R-2R.

Dieser Funktionsgenerator wird von einem Arduino Uno betrieben. Die Frequenz der Signale wird durch ein Potentiometer gesteuert. Wir haben ein 16x2 Display hinzugefügt, das uns die Art der Welle anzeigt, die zu diesem Moment gesendet wird.

Es gibt drei Wellenformen am Ausgang: Sinus, Dreieck und Säge, die Bereiche in Frequenz sind nicht exakt konfiguriert.

I have a little problem with the sine wave: @ 4 Hz it seems to be smooth and consequential, at the increasing of freq, the signal goes to single sinewave + a little stop (seems to have an error into x scaling. Any ideas to fix it? The circuit is the same as yours as the Arduino code

Why does the frequency increase, the period increases, please explain to me. maybe I misunderstood something?

Excelente Trabajo. Gracias. Felicitaciones!

Hi! I see that in the code that is part of Square Function, can you give me some additional instructions? lm386 do you have a preliminary rule? thank you

[stuteerath]

what about square wave generation ? In code you have written the code for square wave then why not in the circuit?

which stimulating software r u using for this please tell me

[baluch]

What is the min and max frequency...Is the output is visiting between+5v and -5 v or only positive wave only

[ranjithar]

The circuit is not clearly visible... Can u share any link to get clear ckt. Also by nw do u hav any idea abt max freq tat cld be attained in this.. Pls do reply.... Thank you

Hello. Whats the name of the software you are using?

[wanessamussagazzepereira]

Hey, nice project! Is it possible to control the amplitude?

hy...
did u share the proteus file....?

Was ist das für ein Simulationsprogramm?

Can you upload the arduino code please?
