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 ...

Abstract: 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 ...

Looking to get a little more creative with your photography and fancy giving high-speed photography a go? Why not create your very own high-speed camera trigger using an Arduino, piezoelectric sensor ...

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 ...

Chapter 1, page 11 This code is basic but allows the reader to gain insight into key elements for several other projects in this book. It combines two pieces of code that are listed in the examples ...

Piezo Trigger Switch circuit described here is a microcontroller-compatible shock/impact sensor switch module works on 5VDC supply. The whole circuit can be assembled on a 5×7 cm common circuit board.
