For the task, we had to get the temperature sensor to sense the temperature and output the temperature in the serial monitor. As the code had been executed, the serial monitor showed the temperature at that time. (See below)

In order to test that the temperature sensor was working, a friend placed their fingers around in the anticipation of the temperature raising – after a few seconds the temperature rose considerably.

This week’s task focused on the input of analogue signals and how they’re converted to work with the digital Arduino. Additionally, we had to get the┬ápotentiometer element to act as a switch for the LED; allowing it to illuminate and dim.

Chapter 9: Photo resistors

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’.
