Скачать или смотреть 10-Minute Arduino Height Sensor: No Breadboard Needed! (HC-SR04 + TM1637 Display)

Hi everyone! Today I’m sharing a super simple Arduino height sensor project that’s perfect for beginners—no breadboard, no soldering, and you can build it in 10 minutes!
What makes this project great?
No breadboard needed: Wire components directly to Arduino (saves time!).
Stable readings: Uses filtering to fix fluctuating values or stuck issues.
Real-time display: Shows height in millimeters on a 4-digit screen.
What you’ll need (3 core parts!):
Arduino Uno/Nano
HC-SR04 ultrasonic sensor
4-digit TM1637 display
Male-to-female jumper wires (8-10 total)
USB cable (for power/code)
Optional: 5V phone charger (for extra stability)
How it works (step-by-step):
Wiring (2 minutes!):
HC-SR04: VCC→5V, GND→GND, Trig→Pin 9, Echo→Pin 10
TM1637 Display: VCC→5V, GND→GND, CLK→Pin 2, DIO→Pin 3
Pro tip: All GND pins must connect together!
Code (3 minutes!):
Install 2 simple libraries: TM1637Display & SimpleKalmanFilter (via Arduino Library Manager).
Copy the code (linked in comments!) and upload to your Arduino.
Test it:
Power on, place an object under the sensor, and watch the display show height in real time!
Troubleshooting tips:
If it gets stuck: Try a 5V external charger for the sensor (fixes power issues).
If values jump: Double-check wiring—loose GND pins cause chaos!
