Let's build a homemade alarm. We will scan continuously the space in front of you through the ultrasonic sensor, with a radius of approximately 30 Â°. When an object or person is in the field of action at a distance less than the established, it will sound an alarm, take a photograph, turn the RGB Led from green to blue (it will give you 10 seconds to deactivate the alarm through our matrix keyboard).
