The second day of the Sketching with Hardware course was dominated by the microcontroller “Arduino”. First, the advisor gave us an overview of the open-source project and the community around the Italian microcontroller. After a short introduction to the structure of the “Arduino” with its input and output pins we proceeded to install the required software on our computers. Once this was done we set out to test first simple examples. When all groups had a unit up and running, we could deal with more complex circuits.

Testing the particular examples was very practical. First, the advisors explained the circuits and their subtleties based on schematic drawings then each group could deal independently with the implementation. Input and output possibilities where covered. This included simple circuits with toggle switches which turned on and off an LED or more elaborate designs, which controlled the vibration velocity of a vibration motor with a variable resistor (potentiometer). The emphasis was on digital-read, analog-read and analog-write concepts.
Often, we were free to use any sensor to implement a particular principle which was fun to us and ensured that we understood the concepts and developed creative designs.

Towards the end of the day, the theme of the project week “Bionic” was presented. Some videos were used to further illustrate it. We were asked to gather ideas over the weekend which we would like to develop during next week.ImageImageImageImage
