Physical Computing Week 9: the browser as input and output

Lab Reflections

This week we worked on connecting the physical computing device as both input and output from a web browser. The lab exercise was to set up an LED that would change its values from both a potentiometer and a slider on a web browser.

The breadboard: a potentiometer and a blue LED wired to an Arduino Uno R4

One of the challenges that we faced was working with a new Arduino, the R4. We had difficulty making it work until we troubleshot it and swapped out the breadboard. That seemed to fix it, which makes me think it was a bad breadboard.
