Second time throught he loop the ,mask, = 00000010, so our operation looks like: 00000010 & 10101010 _____ 00000010 And our output pin gets set to 1. The loop will continue to iterate through each ,bit, in the ,mask, until the 1 gets shifted left off the end of the 8 ,bits, and our ,mask, =0. Then all 8 ,bits, have been sent and our loop exits.

Eduardo shows how to manipulate ,bit,-level data using ,bit, masking and ,bit, fields, demonstrating the strengths of both techniques with an ,Arduino, controller. Then learn how to use the volatile and const variables to enforce data correctness and read-only access, and explore alternatives to traditional functions, which may take too long to run, and floating-point math, which consumes CPU.

A ,bit mask, (or bitmask) is a sequence of ,bits, that can be used with bitwise operations to change or flip ,bits, in a byte or nibble. That may be a convoluted definition so let me give an example using ,Arduino,-style code to try to clarify.

Bit Masks,. ,Bit masks, are used to access specific ,bits, in a byte of data. This is often useful as a method of iteration, for example when sending a byte of data serially out a single pin. In this example the pin needs to change it's state from high to low for each ,bit, in the byte to be transmitted.
