In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Basic motion sensing setup using Arduino, PIR sensor, LEDs, and push button for interaction & Motion-triggered alarm system with Arduino, PIR sensor, piezo buzzer, and LED alert. // first pic This ...

For-fun experiment with an Arduino UNO, where a passive piezo-buzzer’s pitch is controlled by an ultrasonic sensor (HC-SR04). The whole idea of this “pseudo-theremin” is to obtain the proximity to the ...

Abstract: The distribution transformer is an important tool in the power system. During operation, the transformer produces vibrations indicated on its performance. Transformer monitoring based on the ...

Piezo discs have been around since the 1970s, and such cheap (and easy-to-handle) discs are widely used by avid electronic hobbyists and experimenting musicians all over the world. A piezo disk ...

Abstract: The ever-increasing demand for energy in our modern world necessitates exploration of innovative and sustainable solutions. However, the research in the integration of piezoelectric ...
