Goodies bag info

Most of the sensors in your bag come from two sensor kit boxes:

Arduino 37 sensors   Links to an external site.and 26-Module sensor kit

Note that many of these sensors already have a voltage divider on them. This is how they are used:

"S" means signal, connect it to for example analog input in the Arduino
the middle pin that is unmarked, connect it to +5V
"-" means ground, connect it to GND on the Arduino
