Boing! Time to simulate a spring force! This challenge fits into chapters 2 and 3 of the Nature of Code and demonstrates how to simulate the oscillating motion of a spring using vectors and forces.

Featured Challenge:
#188 — Voice Chatbot
In this coding challenge, I build a conversational voice chatbot entirely in the browser with p5.js. I combine three pieces: speech-to-text with OpenAI's Whisper model, text-to-speech with Kokoro TTS, and a "brain" for the bot. I also explore the transformers.js pipeline API and the Web Audio API. For the bot's brain, I start with a simple ELIZA-style therapist, then incorporate a RiveScript number-guessing game, and finally a local LLM.

particle system
In this coding challenge, I explore the concept of a simple particle system and attempt to create a smoke effect with the p5.js library.
In this 4th of July themed coding challenge, I build an HTML5 canvas fireworks simulation from scratch using the p5.js JavaScript library. I also show how to use Processing to create 3D Fireworks.
