If 123 is used as a seed and squared, the answer will be 15129. We can then extract the middle three digits of 15129 to use as our random number, which will be 512. 512 can then be used as a seed for the next random number....

Here's another example using random samples and outputs i.e. non-power of 2 values. #define SAMPLES 1976#define OUTPUTS 153 Here 1976/153 = 12.91 and each bin has 13 values in it except the last that has one. So the algorithm gets it approximately right. ...
It has two arguments: 1) the pin number; and 2) the duty cycle value, expressed as a number between 0 (only LOW signal for the whole period) and 255 (only HIGH signal for the whole period). Notice that hardware wise, it is possible to have more than 8 bit (thus, values from 0...
Now that we know how to display 0-9 on the display, we’ll move forward to see how to produce a random number between 0-9. To achieve this, we use the “random()” function. random(max) “random()” will generate a random number between 0 and max-1. ...
