    ESP32 with TDC1000

    Hello, I want to use the TDC1000 with a single piezo electric transducer and wave reflector to measure the TOF of a liquid (submerged). I want to interface the TDC1000 with an ESP32-S3 but I am not sure if I got the right connections. I just need to get a TOF value from the sensor. I am new to...

    MOSFET Gate Instability? Diagnosing Unexpected Piezo Behavior

    When S1 is closed, it connects to the main 3V supply. However, when this happens, the piezo element starts buzzing loudly—even though the MOSFET gate remains closed. Why is this happening? Interestingly, when a 1k resistor is placed in series with the inductor (not the 32Ω resistor in the...

    Circuit board to amplify and filter the electrical signals from the piezoelectric disks

    Hi, im working on creating a step counter using piezoelectric disks. The idea is that I want to use the disks as sensors and be able to read their voltage and current values with an Arduino Uno. Im also using a voltage sensor, the sensor that will be used is an ACS712 that can detect the flowing...

    Using Piezoelectric disk to charge the chargeable battery.

    Hi, im doing a project on piezoelectric disks where I want to harvest energy from them. I have ordered some and waiting on them, I wonder if someone is familiar with working with these and could answer some questions. thanks in advance
