The Raspberry Pi has been setup to connect wirelessly to the network, where a web interface can be accessed which sends commands to a ‘controller’ script. There are two aspects to the build, the blind opener and airconditioning control. The easystepper motor driver is interfaced to an old stepper motor which drives the blinds. The step pulses are sent using the GPIO library. The LIRC library was used to record and send infrared information to control the air conditioning. The information had to be recorded in RAW mode, as the information length was longer than normal.
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
