What is the best way to create a timer that counts up and down automatically?

[ylevental]

I want the timer to automatically count up and down from zero to a certain value.

Sounds like a simple application that can be done with a While Loop with some Shift Registers to hold state and counter value.

What have you tried?

I built a countdown timer from this guide, but I don't know how to proceed

This is what I have so far but it only counts down to zero

[crossrulz]

I recommend using a boolean (stored in a shift register) to state whether your values are incrementing or decrementing.  Then you just use a case structure for your two different methods.

Honestly, I don't know how to do that
