What were the key points from the video?
- Monsters are silly!
- Conductors allow electricity to flow through them
- Insulators do not allow electricity to flow through them
- Semiconductors allow some electricity to flow.
- An LED is made of two different materials (Semiconductors). When you shine a light on them, the materials change slightly. This change can be measured.
- You can use LEDs as a crude light sensor.
Can I build a program to take a reading?
What is a variable?
Variables are used in computer programming to store specific values within a program. For example, the variable in this program is the light reading - a number between 0-255.
Now build the program with your partner.
