hello world.. peace to all...
this is my 1st post here. i need some advice about my FYP. actually, i have been given from my lecturer about shooting target retreival system project and i'm doing this system alone. after a study, i found that i can use PIC as microcontroller. the system will consist 4x4 keypad and lcd dispay. this is how it's work.. we need to put our desired range on the keypad such as 20meter and it will display on the lcd. after that a motor will move a cable that hang the target according to the range that we put on the kaypad. the problem that i found is, how can pic remember the last range that i put. like when i ask to go to 30meter it will know that the current range is 20meter. actually i need to make a prototype for this system. need someone to give me any advice for my project. some circuit or diagram are really helpfull. i really appreciate any advice now.
(my english is bad.. hope u dont mind)
thanks..
