Introduction: Hunchback Correction

Many people have problems with hunchback, which not only affects the appearance, and also cause numbness in shoulders and necks. So I designed a device to improve hunchback, and this device is mainly suitable for people with incorrect sitting position (People who sit and often hump). This device is not difficult, it can be made using only some basic principles, so let's get start it !!

Step 1: Equipment

1. Arduino

2. Breadboard

3. LCD

4. Ultrasonic Sensor (I use HC-SR04)

5. Lots of wires

Step 2: Circuit Diagram

Step 3: Code

Step 4: Video
