This is one of my favourite circuits now
It's a 4 waves generator only digital! The only analog parts are the resistors and 555 and the capacitor.
All the credits for the sine wave goes to faceblast and our god hurz ;-)
You can regulate the frequency with the 555 by changing resistor's value of the 555.
In this circuit you can see:
Square wave (orange)
Triangle wave (blue)
Saw tooth wave (green)
Sine wave (red)
You can actually build this in real life but i'm going to use arduino for the digital part.
Happy new year :-)
