This week in Adventures in Science, we examine the various data types in Arduino and how to use literals and variables. While there are only 3 fundamental data types in C, Arduino supports many more. You can also extend various data types by adding keywords like "long" to create a "long int" that uses 4 bytes (instead of 2 in most systems).
