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
