ESP32-S3 peripheral tour (no typing)
Fully autonomous: a stock ESP-IDF app on the ESP32-S3 writes the OLED over I2C, animates the NeoPixel strip over RMT, and reads the pot on ADC1. Just press Run.
How it works
A whole ESP-IDF peripheral tour compiled for the S3 and run through the real boot ROM, no typing required. The app drives three peripherals at once: the SSD1306 over I²C (SDA=G8, SCL=G9), an 8-pixel WS2812 strip animated through the RMT peripheral on G3 (the same cycle-exact bit timing real firmware needs), and the potentiometer read on ADC1 via G1. It is the closest thing on the bench to flashing a random devkit demo and watching it go.

This project runs prebuilt firmware on the emulated board; open it in the simulator to watch it work and inspect every part live.
Try this
- Watch the NeoPixel animation run: that is the RMT peripheral making WS2812 timing.
- Turn the pot's Inspector slider and feed the ADC a new reading.
- Open the Serial panel for the app’s own logging.
- Press ⟲ Restart to watch the IDF boot sequence from the top.
