Smart Shades
Custom ESP32 firmware that automates residential shades: H-bridge PWM control (TB6612FNG) of high-torque worm-gear motors with sub-100 ms response, plus Tuya IoT cloud control, schedules and manual overrides from a phone.

Problem & approach
The problem
Automate ordinary residential shades: drive heavy worm-gear motors reliably, and control them remotely, on a schedule or by hand.
The approach
An ESP32 with a TB6612FNG H-bridge driver and custom firmware, integrated with the Tuya IoT ecosystem for telemetry and cloud control.
