The LMU SKWH 2020 - LMU Sketching with Hardware course (Summer Term 2020) we have completed the Preparation phase (self-paced), and done the Individual Tasks. Please get organized in your group.

We will answer your questions in the discord server (links below).

Todos for you:

• Please provide the planing (time, shopping, milestones, topic) for your group project - see https://www.sketching-with-hardware.org/wiki/Group_Project_SoSe2020#Requirements
• there is a Feedback page - if you encounter(ed) any issue with the information, kit, video - please let us know

Here are some recent changes:

• There is now more information about the RGB LED including a tutorial video: https://www.youtube.com/watch?v=K2m6ttZ1bJw
• There is an example of how to program the LED Ring NeoPixel
• The page describing the LED is now setup as example
• Tutorial pages are up: Tutorial Basics, Tutorial Digital IO, Tutorial Analog IN, Tutorial Display, and Tutorial Network
• There are pages with the Individual Tasks as well as for the Group Project SoSe2020
• There is a description of the Tasks_SoSe2020

Courses

At this point there is only one course (summer term 2020 at LMU) ... but we hope for more in the future.

Please go to the course page for details, timeline, and requirements:

• LMU SKWH 2020 - LMU Sketching with Hardware, Summer Term 2020
• there is also a gallery with results from the last course: Gallery 2020

Foreword and Introduction to Sketching With Hardware

The course is part of our question of how to create functional prototypes for exploring interactive systems. There are some introductory slides ( pptx, pdf) that are shown in the introductory video (https://youtu.be/Irxo9b5cexs).

In the article "Understanding and researching through making: a plea for functional prototypes" (in the ACM DL , as PDF) we discuss three different approaches to create prototypes. In this course, we focusing custom hardware development for research and development in human-computer interaction.

Learning Goals

The overall learning goal is the equip students with skills to Envision a new interactive physical object and implements a functional prototype, this includes:

• understand why sketching with hardware is relevant
• understand the challenges in creating function prototypes
• being able to create basic hardware sketches
• being able to program and debug MicroPython on ESP32/ESP8266
• being able to build basic circuits connected to the microcontroller, including
  • output: LEDs, servos, motors, speakers, display
  • input: buttons, dials, sliders, LDR, accelerometer, distance, I2C sensors
• being able to program basic networking (network variables)
