Figure an Arduino most matches the "Other" category. To be specific, it isn't an Arduino brand, it is a DigiSpark, but the trouble isn't with the device itself. The problem is with a buzzer. I got the ...

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 ...

This project uses an HC-SR04 ultrasonic sensor to measure how close an object is. A buzzer and LED react depending on the distance, similar to a car parking sensor. < 10 cm → buzzer and LED stay on.
