Nov 20, 2016 · The next step is to connect a 10 Kilo Ohm resistor between 10 th pin of Arduino UNO and 5V supply i.e. the 10 th pin of the Arduino is pulled high. Hence, 10 th pin of the Arduino will continuously detect logic HIGH. Now connect one end of the switch or button to the 10 th pin of the Arduino and the other end is connected to ground. The power supply to the breadboard can be given from 5V and GND pins of the Arduino UNO. Note that the code seeds the random number generator using a high-precision clock. This is important for avoiding hacks specifically tailored to your code, since using a fixed seed means that For more details, see How randomized solutions can be hacked, and how to make your solution unhackable.
