Circuit 6: Photo Resistor

This circuit is a LED that goes from bright to dim depending on how much light it receives.

Completed Circuit

The photo sensor detects light so it turns on the LED.

Circuit Code

Look at the parameters that show what high and low light levels are.

Circuit 7: Temperature Sensor

A sensor that can read the temperature and then posts it in the code.

Completed Circuit

The sensor one the board is able to provide a reading of the temperature.

Circuit Code

The important line here is the formula that provide a voltage based on the temperature.

Circuit 8: Buzzer

A small buzzer that can play notes to create a song.

Completed Circuit

The black circle will produce a sound and that can be turned into a song.

Circuit Code

See how the beats affect the out come of the song.
