Another Arduino project for newbies

Posted on Feb 6, 2014

Electronic devices love accuracy. If you give them the same task twice, you will get the same resault. But sometimes you want some random result. This can be used in games. You can create your own lottery game. We will help you to do that kind of game with this Arduino project. It can also be used in other situations. Like a random walk,  wher

e a robot makes a random turn, then walks a random distance or until it hits some object. It is more natural movement if robot moves this way. You newer know what it will do next. It might be very funny. The Arduino library has a algorithm for generating random numbers. There are two versions of the algorithm random. It can either take only one argument (max) or two arguments (min and max). In first case the minimum is assumed to be zero. Be careful, because the max argument can be misleading, as the biggest number you can get back is the max minus 1. So, the this line will give x a value of 1 to 6: Next step is to connect this components by the schematics below. You can build the circuit by connecting the parts directly or you can use the breadboard. Using breadboard is a better way because it looks better and orderly. Even though a dice can only have a max of six dots, we will need seven diodes to have the of a dot in the middle for one, three and five rolls. It is a dot in the middle of the area. After you created the circuit, next step is to program the Arduino board. You can program the board by using the Arduino software provided in the board package. Here is the software. You can copy/paste it, but it is not complex, the best way it to write it by yourself and when you have a problem, you can look below. We have 7 diodes to initialize in the method, so it is good putting them in an array and have a loop over the...
