Somebody that knows how to make circuits in Tinkercad and knows how to code using the text code option for C++ on Tinkercad, please help!

I have an assignment that I am almost done with but I am having difficulties with the RGB LED SOS part of it. I need an RGB LED to blink an SOS with the color red doing an SOS, green doing an SOS, and blue doing an SOS. I REALLY need help with it. If you know how to code that for me using this screenshot of my circuit with C++ on tinkercad please let me know! Thanks!! Please make a code that will work my circuit. Thank you so much!
