- I need suggestions on the type of micro controller I can use to make a count down/delay timer along with a potentiometer. Which one has the smallest features but enough memory to do this task?
- Basically, when tuning the potentiometer say to 1 minute, the microcontroller will turn on the buzzer at 1 minute. If I tune the potentiometer say to 10 minutes, the buzzer should beep exactly at 10 minutes. Tuned to 30 minutes, it beeps at 30 minutes, etc... All buzzing would only buzz for 30 seconds.
- Does it only require that a potentiometer and a capacitor be used along with the micro controller and that is it?
Some time interval options I thought of for the timer when using the potentiometer:
Minutes: 5 - 10 - 15 - 20 - 25 - 30
Minutes: 10 - 20 - 30
Minutes: 15 - 30 - 60
