Task 1. First image shows ambient light intensity, Second image shows LED light intensity, third image shows the osillation of the sensed light around the setpoint.
Task 2
Figure 2. Video shows oscillation around the set point after adding an LED with a pushbutton. we can see the oscillation going back to the setpoint.
Figure 3. Python was used to save our data and implement a graph where we can see the light intensity over time (spikes represent the pushbutton being pressed).

Task 3
Figure 4. Setpoint tracking represented in arduino, the oscillation follows the setpoint. the setpoint is moved up by 20 points when the pushbutton is pressed.
Figure 5. Python was used to collect and save the data, a plot was implemented to better visualize the data.

Discussion
Overall
this lab was very important. We learned and understood what a PID
controller is and how it can be implemented. I can already tell they
are important since it implements feedback perfectly. Working with LDR
resistors is always fun, they are very useful for closed loop systems
in general. The final tasks of this lab required the use of python to
collect and plot data. This was an interesting hange of pace since it
required us to work with two programming languages at the same time,
challenging but fun. I look forward to implementing python with more
projects since in the futureI know this will be the case.Looking forward to the next homework.
