Display Group Number & Control Led With Joystick



Description:
In this program we are going to show our group number 1 in 8x8 led board and controlled led with joystick.

Step 1:
Materials Required
1.     Arduino (We use UNO)
2.     8x8 Led Matrix (Red)
3.     Joy Stick
4.     Jumper wires Male - Female

Software Required
1.     Arduino IDE (We use NSight Eclipse)

Step 2:
Uploading Arduino Program

Demo View:
After uploading arduino program led shows our group number 1. Number stays 5 seconds. After that all led turn off and only middle led (row 4 & col 4) will turn on. Then we can control this led with joystick. If we move joystick handle left the led goes one column left. If we move joystick handle right then the led goes one column right.

Solution - Timus Problem 1293. Eniya

1293. Eniya Time limit: 1.0 second Memory limit: 64 MB It’s restless now on the slips of the intergalactic port’s sixth dock of planet of Torn. No longer then in a month the reconstruction of the small ironclad corvette “Eniya” will be finished. And again this battle ship and its brave team would have to struggle for the control over plutonium mines of Sibelius. The work cannot be stopped even for a second, self-powered laser welders work round the clock. Joints of robots-repairers fuse because of this permanent work. Nevertheless, they can’t stop not for a single moment. Now in all this turmoil it is discovered that corvette’s thermopanels again need an urgent processing with thorium sulphide. It is known that the processing of the one square meter of the panel needs 1 nanogramm of sulphide. In general, it is needed to process  N  rectangular panels, which dimensions are  A  by  B  meters. It is necessary to calculate as fast as possible, how m...

Solution - Codeforces Problem 327B - Hungry Sequence

B. Hungry Sequence Iahub and Iahubina went to a date at a luxury restaurant. Everything went fine until paying for the food. Instead of money, the waiter wants Iahub to write a Hungry sequence consisting of  n  integers. A sequence  a 1 ,  a 2 , ...,  a n , consisting of  n  integers, is  Hungry  if and only if: Its elements are in increasing order. That is an inequality  a i  <  a j  holds for any two indices  i ,  j   ( i  <  j ) . For any two indices  i  and  j   ( i  <  j ) ,  a j  must  not  be divisible by  a i . Iahub is in trouble, so he asks you for help. Find a Hungry sequence with  n  elements. Input The input contains a single integer:  n  ( 1 ≤  n  ≤ 10 5 ). Output Output a line that contains  n  space-separated integers  a 1   a 2 , ...,  a n   (1 ≤  a i  ≤ 10 7 ) , representing a ...

Solution - Timus Problem 1409. Two Gangsters

1409. Two Gangsters Time limit: 1.0 second Memory limit: 64 MB Two gangsters Harry and Larry had a rest at countryside. They decided to spend some time shooting, so they put several beer cans (no more than 10) on a log. Harry started to shoot cans one after another from the leftmost to the right and Larry – from the rightmost to the left. At some moment it happened so that they shot one and the same can. Harry got indignant and claimed that Larry owed him a considerable sum of money because Larry deprived him of shooting some more cans. Larry became furious and told Harry that he owed even greater sum of money to Larry because of the same reason. They started to argufy but nobody remembered how many cans there were at the very beginning. And no one of them was going to search cans which was shot. Anyway, each of them remembered exactly how many cans he shot. Determine how many cans were not shot by Harry and how many cans were not shot by Larry. Input The only inp...
