By default in the ,Arduino, firmware interrupts are enabled. Interrupt masks are enabled / disabled by setting or clearing ,bits, in the Interrupt ,mask, register (TIMSKx). When an interrupt occurs, a flag in the interrupt flag register (TIFRx) is been set.

The ,bit mask, is computed from ,bit, number in a straightforward way by ,bit, shift: (1 << ,bit,_number). This method looks promising, but there are drawbacks. First, it would require renumbering the pins on the ,Arduino, board - surely not feasible.

I made this ,Arduino, 8 ,bit, binary led counter as a solution for one member from ,Arduino, forum. He asked if somebody can make a project that displays a decimal number in 8 ,bit, binary format using 8 leds where a 1 is represented as a lit led. This project can be used in schools to display a binary number using leds.

While this can be effective, these coverings can be hot, inhibit breathing, and certainly make eating and drinking a ,bit, difficult. What if they could instead be applied only when others are around? Chen the DesignMaker decided to test this concept out with a servo-actuated ,mask, , which features a hatch that actuates based on input from three PIR sensors and an ,Arduino, Nano .

Reading a ,Bit,. Registers are not only written to, but they are also read from. To read if the value of a certain ,bit, in a register is a 0 or a 1, we ,mask, all of the other ,bits, to a 0 (leaving the desired ,bit, unaltered), and then check the resulting number. If the result is all 0’s, we know that the desired ,bit, …

The result value for the operator & is the bitwise AND of the operand values.. It means that when applied to two integers (in binary representation), it will result in an integer where each ,bit, will be set to 1 only if both ,bits, at the same position where 1, else to 0.

Since ,mask, is a byte (which is 8 ,bits,), it will go all the way up to 10000000 and then stop. After that, the 1 effectively falls-off the left and ,mask, ends up with a value of 0. The purpose of this in the code you provided is to test each individual ,bit, within the data parameter.

Arduino, hardware has a tendency to randomly assign device pins to connector pins, my guess is to simplify board layout. Some processors don’t have ,bit,-addressable I/O ports. One must read a byte or 16 ,bit, word, modify a ,bit, in it and write that ba...

where y is the register type (B/C/D) and xxxxxxxx are eight ,bits, that determine if a pin is to be an input or output. Use 0 for input. The LSB (least-significant ,bit, [the one on the right!]) is the lowest pin number for that register. Next, to read the status of the pins we simply read the …
