Hello all,
I hope this is the right forum to post this question.
As the subject line says, I'm looking to build a timer that can be adjusted (let's say between 10 seconds and one hour) and I want it to sound an alarm once the timer reaches zero.
In addition, I want my prototype to display the amount of time left.
What microcontroller and display controller would you pick if you had to build something like this?
One more thing - this device will be portable, so it must be battery-powered; at this point I'm thinking 3V but I'm willing to consider other options.
Any feedback would be appreciated.
