7400 competition entry: Lighting effects generator
The basis of the device is a multi-bit digital sequence generator that is implemented on a serial shift register . The repetition period of the sequence is determined by the number of bit of a register and much higher than the repetition period clock. For a sequence containing all possible states of the register, excepting the zero state (so-called M-sequence) the value of the period is Tn = (2n-1) / f, where n – number of bit of a register, f – clock frequency in Hz.Via the contact form.
