For this I need uC,Keypad,Display also. No, you don't need a keypad, and you don't need a display! I am looking rather simple solution. So don't overcomplicate with unnecessary extras like keypads and displays! eg, Just use a rotary switch to set the delay. Some of the really cheap little microcontrollers do have analogue-to-digital input - so you could use a potentiometer to set the delay. Please explore in this direction. Your original post did specifically ask about doing it with a microcontroller, didn't it?! |
