However, the algorithm being used on Arduino to make random number generator function cannot ensure the randomness of the challenge value, thus this paper will propose another algorithm to be used as challenge value that can cover the weakness mentioned. The proposed algorithm is actually one of ...
The reading from analogRead has been a staple as a seed for the Arduino built-in pseudo-random number generator. It usually goes like this:randomSeed( analogRead(A0) ); long randNumber = random(10, 10000); Serial.println(randNumber); ...
smart reseed needed for random(). initialize random generator with compile file + date + time. use function values for seed bits. stand-alone functions in separate .h clean up codeCouldASDR wave https://en.wikipedia.org/wiki/Envelope_(music) float ADSR(float t, float A, float D, ...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
To generate a random background color, I use a pseudo-random number generator to generate random RGB values and I assign the resulting color to a new Brush object. We must use Dispatcher.Invoke() to make changes to the UI thread, because the thread triggered by the event handler does not...

The following code fragment sets up fast PWM on pins 3 and 11 (Timer 2), using OCR2A as the top value for the timer. The waveform generation mode bits WGM are set to to 111 for fast PWM with OCRA controlling the top limit. The OCR2A top limit is arbitrarily set to 180, and the...
