Here is a n bit counter code for arduino... Its totally easy to use and you can modify it to create an alternate count way (count-up, count-down...). You can modify the number of bits and the max number to count.

Step 1: Download the Code, or Copy It.

You can download it from here.

Step 2: Edit It As You Want...

The code have some control constants to make it works fine...

Some of that constants is:

  • Frecuencia: Its the number of samples per second that you wish.
  • nbits: Its the number of bits that you want to have the counter (ex. nbits =4 ==> 1111)
  • nMax: It is a number that determines to which number the counter can count.
  • sal[]: It is a vector that have the pin number of the output.

You can change that numbers to modify it as you want.

Note: the sal[] vector numbers must be equal to nbits number.

Step 3: Upload the Code and Conect the Entire Circuit.

You can conect the arduino to some devices like: led array, a DAC, a FPGA...

Also you can view the functionality though the Serial...

<p>Interesting project.</p>
