Welcome to the Piezo SHOCK Show #45. Now, the last thing you think of when talking about a piezo buzzer is an amplifier or a transformer. But, in this video, that's all I'll be talking about. Ultrasonic devices with three unique terminals have the ability to be used as step-up or step-down transformers. I demonstrate this using a three terminal piezo buzzer. OMG!!! A video making a BUZZER into a TRANSFORMER!! A MUST WATCH!!!
