Introduction This project proposes developing a compact, wearable Morse code glove with piezoelectric sensors to detect finger taps. The glove sends signals to an Arduino microcontroller, which ...

Materials Required Arduino Uno Piezoelectric transducer 1N4007 diode Capacitor (10 µF or 100 µF, 25V) LED Resistor (220 ohms) Breadboard and jumper wires Circuit Diagram Description Piezo Transducer: ...

The piezo disc sensor head (see above circuit) will keep A0 of Arduino at 0 V until it’s disturbed. Once the hardware setup is completed, upload the code, and hit the sensor head with your finger. In ...

After uploading the code the Piezo will start making short beeps. On bright light the Piezo will only beep and on dark light it will be short. Some ideas for this experiment: Alarm for Lights in the ...

This paper proposes the use of Rochelle salt (KNaC4O6.4H2O) as a piezoelectric sensor for efficient smart energy saving systems. The piezoelectric properties of Rochelle salt tested for different ...
