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 ...

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 ...

The project utilizes an Arduino to produce a drum kit which comes with four piezo sensors, PCB, and other required to make it work with Arduino as a mini shield. In the design, there are 3 sections ...
