Teensy 4.1 - Piezo Drum Trigger Signal Conditioner Interface (4-ch)

PCBWay Supports High Precision Advanced PCBs: https://www.pcbway.com/ 0:00 Intro 0:31 Observe piezo raw signal 1:48 Begin signal conditioning 2:24 Rectify signal 2:59 Peak detector 5:00 Clamp voltage 5:48 Schematic Design 8:58 Ordering PCBs from pcbway.com 9:26 PCB hook up to Teensy 4.1 and Adafruit I2S audio board 10:09 Sketch overview 11:57 Trigger input detection algorithm 13:36 Drum Demo When piezo transducers are mechanically struck, they generate voltage spikes that can vary in voltage level, polarity, and active duration. The voltages can be a few volts or many tens of volts. This pcb provides an interface between piezo elements and a microcontroller input (analog or digital). It limits the voltages to safe levels, filters them, and provides a more consistent level-sensitive output as the device is struck with varying intensity. This pcb provides a 4 channel signal conditioner, allowing piezo elements to be used in a drum sample player on Teensy 4.1 Sketch, schematic and wiring diagram: https://github.com/GadgetReboot/Piezo...
