It’s powered by an Arduino Diecimila with an Adafruit Ethernet shield. The Arduino reads an online PHP script every five seconds. The PHP script uses the Twitter search API to search Twitter for the desired word(s), and finds the latest matching tweet. It determines if this tweet has been found previously, or if it’s new. The result is sent back to the Arduino. An LED flashes every time a successful connection is made.
If the tweet is new, the Arduino plays four bars of samba-style rhythms. At the start of each bar, each instrument chooses randomly from a set of pre-written patterns, so there are many possible combinations.
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
