Here's an image of the circuit for some specific time:Īnd the code that generates the sine wave is #include įloat sf = 500.0 // sample frequency > 2*f (Nyquist) Wokwi Arduino simulator is a browser-based simulator where you will build your projects. Designed for people in hardware need The Arduino Simulator has been drastically changed the way you use a simulator. I'm currently working on a simulator online, so I thought it would be best to share the circuit with the c++ code, and perhaps you would have any insights on why I keep seeing rectangular output voltage rather than sine when the data is indeed a sine wave: The Arduino Simulator is available for free, activate the software with this license key: 5FVKL-CMSM2-ZH9EX-UAFIX-AKRN9. The process is quite simple, but I couldn't see the actual sine wave when connecting an oscilloscope. Trying to create this simple circuit where a rectangular voltage input is transferred to a sine wave output.
