Cheap Haptic Feedback Vest

This tutorial is how to make a cheap yet functional haptic feedback vest.

Step 1: Materials List

Cheap Haptic Feedback Vest
  • 1 Vest (Ideally with pockets or compartments to hold electronics)
  • 2-4 Ultrasonic Sensors
  • 1 Vibration motor for every sensor
  • Wires
  • Arduino
  • Transistors
  • Arduino ProtoShield

    Step 2: Procedures (Wiring)

    Step 1: Connect ultrasonic sensors to power

    Step 2: Connect input/output ports of the ultrasonic sensors to the analog ports of the Arduino

    Step 3: Set up power wires for transistors that are connected to the motors in a parallel circuit (Positive voltage connects to the first lead of the transistor)

    Step 4: After connecting transistors to power, connect each transistor to a different port on the Arduino (Data wires connect to the middle pin of the transistor)

    Step 5: Connect motors to the transistors (One side of the motor connects to the third pin and the other side connects to ground)

    Step 3: Procedures (Programming)

    The program is set to vibrate if anything is within 2 feet. adjust the values as needed and if there is lag lower the delays. this program works with no issues; to add more sensors just copy and paste what happens from each previous sensor and adjust everything accordingly.

    For your vest you can design the covers anyway you like. Just be sure to make the cover a little bigger on the CAD system because if you were to 3D print it it would shrink and may not fit if it shrinks too much. I have included the covers I made with all the dimensions accurate to the VEX Ultrasonic sensors.
