What's better: #define or static const? (self. arduino) submitted 4 years ago by MooseV2. I know what they each do, and (think) I know what their differences are. The const does indeed use memory, but the impact should be negligible due to the compiler's optimizations. It's strongly typed, which is nice.

Constants are predefined expressions in the Arduino language. They are used to make the programs easier to read. We classify constants in groups: Defining Logical Levels: true and false (Boolean Constants) Most Arduino boards have a pin connected to an on-board LED in series with a resistor.
