Скачать или смотреть Why I Ditched Touchscreens for Industrial Pushbuttons

I tried to build a modern, "smart" touchscreen GUI for the Falco Network using a 7-inch Nextion display. After hours of programming, designing graphics, and fighting with hexadecimal codes just to track button states on the Arduino backend, I realized one thing: touchscreens belong in the trash.

In this video, I rip out the complicated, fragile consumer tech and go back to basics. We are building the ultimate, over-engineered Falco GUI using tactile, industrial-grade hardware. It might look like a control panel from a 1960s space movie, but in an environment where reliability is the only thing that matters, hardwired simplicity wins every single time.

🛠️ What’s in this video:

0:00 - Why the Nextion 7.0 Display is a programmer's nightmare.

3:50 - The new layout: LCDs, rotary switches, and industrial buttons.

6:36 - The Wiring: Arduino Uno R4, I2C busses, and active-low logic.

7:56 - Integrating 3.3V and 5V components safely.

9:31 - Why over-engineered simplicity is the best kind of engineering.

⚙️ Hardware Used in This Build:

Microcontroller: Arduino Uno R4 WiFi

The Reject: Nextion 7.0" HMI Display

Displays: 20x4 and 16x2 I2C LCD Screens

Encoders: SparkFun Qwiic Twist (RGB Rotary Encoders)

Switches: 12-Position Rotary Selector Switch & Industrial Green Pushbutton

Power: Meanwell 110V AC to 5V DC Power Supply

Wiring: Wago 221 Wire Splicing Connectors

Actuator: "Vertical Linear Actuator" (aka a heavy-duty pull cord)

God bless, and I'll see you in the next one.
