Chapter 9: Photo resistors

In input/output on February 13, 2014 at 11:25 am

This task focused on yet more (slight) human interaction. The use of photo resistors. Securing the photo resistor to the Ardunio allowed the LED attached to the board to be controlled by light; the more the photo resistor is exposed to light, the more the LED illuminates.

As part of additional exercises, the ability to cut the LED after a ‘threshold’ was added, this allowed the Ardunio board to work as ‘night light’.
