How it works
The system is intended to recreate the effect of a rolling dice as an instrument to generate random numbers between 1 to 6 after hitting a input button. After releasing the button, the counter that initally counts in a rapid way decreases it's counting speed to simulate a roll-off effect. After the dice finally finishes counting, an external LED signalizes that the user can start to read the resulting number.
How to test
Press the trigger button to start the counter and keep it pressed for a certain time (for example 2 seconds). Release the button and after approx. 7 seconds the number on the 7-segment display shows you a random number in the range of 1 to 6. Meanwhile LED "Pulsecount" starts to flash each time the counter counts one up. After the process is done, LED "Finish" lights up and signalizes, no further counts can be expected.
External hardware
- 2 LEDs connected as active low, LED1 (Pulsecount) connected to bidirectional pin[0] and LED2 (Finish) to bidirectional pin[1].
- 1 7-segment display in common-anode configuration (or 2-digit 7-segment display connected to PMOD, whereas only one of the digits is used).
- Pin "COMMON" can be ignored if using an general purpose LED Display and only outputs a LOW signallevel.
- 1 button for triggering in active high configuration
