Testing #Motorcycle Apparel for Women … with #Arduino! @WorseWear
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.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
