Abstract. A method is presented for obtaining pseudo-random numbers to be used further in the development of interactive applications on the Unity engine with the collection of information from pressure and color sensors connected to the Arduino microcontroller. The method involves using the results of periodic measurements of pressure, temperature, illumination, and colors on RGB channels in a room, bit shifting them by a random number of digits, obtaining the “grain” of a pseudo-random number generator by taking the remainder after comparing the number with the current UNIX time. An application is been developed that implements the proposed method of generating pseudorandom numbers. The uniformity of distribution is checked and the correlation coefficient is assessed using a sample of random numbers.

Keywords: random numbers, pseudo-random numbers generator, interactive applications, pressure sensor, color sensor, Arduino, Unity
