HC-SR04 Ultrasonic Range Sensor on the Raspberry Pi In previous tutorials we've outlined temperature sensing, PIR motion controllers and buttons and switches, all of which can plug directly into the Raspberry Pi's GPIO ports. The HC-SR04 ultrasonic range finder is very simple to use, however the signal it outputs needs to be converted from 5V to 3.3V so as not to damage our Raspberry Pi! We'll introduce some Physics along with Electronics in this tutorial in order to explain each step! What you'll need: Maker Ed’s Summer Institute Note: the Maker Ed Summer Institute requires an application to attend. Applications were due on March 25th, 2019 and are now closed. If you’d like to hear about future professional development events and opportunities as soon as they are announced, consider subscribing to our monthly newsletter!

Many of the early pioneers of parametric design have gone on to do other things – or nothing at all – but Woodbury has defined his career by studying parametric design and in particular, how designers use parametric software. The list of papers he has written on the subject is a paper in itself. That is to say, when Woodbury writes a book titled “Elements of Parametric Design,” take notice. But take no notice of the cover, a bad Wordle design, the cover really undersells it. Elements of Parametric Design (July 2010) is perhaps Woodbury’s magnum opus, it is certainly a labour of love, the accumulation of almost twenty years studying parametric design.
ibm Navigate through the phases of the Cloud Garage Method lifecycle. Each hexagon represents a lifecycle phase with associated practices and tools. Culture permeates all lifecycle phases. The changes in an organization’s behavior and attitude are what enable it to adopt new practices and transform. Music You Can See: 4 Steps You're basically there! Grab/find/scavenge for an oscilloscope, and you'll find that it's worth it given the number of experiments that they can assist with. Hook up the two leads from one of the channels to the two gator clips coming out of your keyboard, and you're almost set. The two main variables you'll mess with are the Time/Div variable (x-axis calibration) and the Volts/Div (y-axis calibration).
