The moving objects are detected by the PIR motion sensor which send the signal to Arduino which again sends the signal to piezoelectric buzzer. The piezoelectric buzzer starts playing the predefined alarming tune. Also, an LED is turned on as soon as the motion is detected. A one way ...
Create an alarm system with PIR motion sensor and buzzer With some simple changes, you can create an alarm system with the HC-SR501 and apiezoelectric buzzer. I connected the buzzer with a 100 Ω resistor between digital pin 5 and GND. You can probably use the buzzer without a resistor (...

By far the biggest challenge I had during this project was figuring out how to detect goals. Each player has their own net, and their own ball return slot, so that made my life a little easier. My first idea was to use a PIR motion sensor (like you’d find in a home alarm system...
