Lab work -The circuit playground involves programming the circuit program with software mainly Arduino and producing an output on the playground itself. This link sends you to the basic project I made to prove my basic understanding of this concept.
Final Circuit playground project - After proving my basic concept, I came up with this project using your Circuit Playground Express. The project creates some kind of light output that changes over time depending on light levels). I used the built-in neo pixels.
This picture is the output I received from the Circuit playground after programming it.
