🚀 Build Your Own Touchscreen Desk Controller with ESP32 + Nextion + ESPHome!

In today’s video, we’re building a touchscreen smart desk controller from scratch using a Nextion display, an ESP32, and ESPHome.

You’ll see the full process step-by-step: ✅ Designing the UI in the Nextion Editor
✅ Uploading the .TFT file using an FT232 USB-to-Serial adapter
✅ Wiring everything together
✅ Writing the ESPHome code
✅ Flashing the ESP32
✅ Live demo with desk & light controls — all smart-home integrated!

By the end, you’ll have a working touchscreen controller that can control your sit/stand desk, lights, and other Home Assistant devices. Perfect for smart office setups, automations, and DIY lovers!
