Kresmo is an Arduino sketch that uses an OpenAI-compatible API to generate a random and brief pithy saying. The sketch uses the U8g2 library for displaying text on an OLED screen, and the WiFi library for connecting to the internet. The ESP32-C3-0.42 module combines all this hardware into one tiny board.
The C3 is similar to the ESP32 - but uses RISC V as a core, not Tensilica, and has Bluetooth LE (not classic!)
