An Arduino Uno is used to record the amount of time it takes to sand through the fabric sample. The method we use is based on European Union standards for motorcycle safety gear testing. To measure the fabric’s abrasion time, we use two thin copper wires (magnet wire). One wire is placed inside and another outside of the fabric sample before everything is wrapped around the head of the hammer. Each wire is then connected to ground on one end and an to input pin on the Arduino on the other end. The pins are in INPUT_PULLUP mode so a current runs through them. The LCD display on the Arduino tells us when both wires are connected properly.
