Process

• I first did not connect a resistor to the photoresistor in series, and I noticed the reading is always similarly high. After consulting with Daragh and fixing this issue, I also noticed that the LED brightness change is too subtle to tell. Daragh inspired me to map the reading from a smaller range, and the LED brightness change is there more obvious.
• Thinking about a real-life implication, I changed the mapping to reverse. So the LED is considered as a light that responds to the surrounding.
