How to Generate Sine Wave using Arduino??
Why people recommend it
A tutorial people have followed to produce a sine wave from Arduino PWM and a capacitor, then checked on a scope, sometimes with trouble getting a clean trace.
Watch for: Output is filtered PWM, and scope triggering may need adjusting
In their words
I followed a youtube video to setup a sine wave using an Arduino Uno and a capacitor to detect on my Tektronix 2235.
