This tutorial introduces 5-way joystick and implements multi-direction key detection with MicroPython GPIO interrupts.

This tutorial covers EC11 rotary encoder and its MicroPython interrupt experiment with a terminal progress bar.

It introduces 28BYJ-48 stepper motor and ULN2003 driver, and demonstrates single-phase driving experiment on Fengya No.1 board via MicroPython GPIO control.

A PV-system bridge with an ESP32-C6 as its "brain": W5500 wired Ethernet talks MQTT to Victron, while Zigbee exposes battery values to Home Assistant.

HaphazardBridge uses ESP32-S3 and W5500 to link Ethernet-only SDRs to ATAK over Wi-Fi, adding NAT, gRPC, CoT relays, and two field modes.

lamePod combines ESP32-S3, W5500 Ethernet, TAS5805M audio, and an XVF3800 mic array in an early, privacy-focused DIY smart-speaker design.
