Babylon Five Imitation Doorbell

This unique project replicates a sound from the “Babylon 5” TV series  (WB) for a doorbell. Using few external components, including an audio amplifier and power supply regulators, the CY8C2213 microcontroller-based system recreates the show’s signature sound with three short 366-Hz bursts followed by a longer 733-Hz burst.
