take one counter variable count
increment it with count++
decrement it with count–
to display count on LCD first saparate all its digit like it count is 15 saparate 1 and 5
then convert all digits into ASCII by adding 30h like 1 = 31h and 5 = 35h
then just display these 31h and 35h on LCD by sending data
