Alarms system with a four digit security code. The alarm system uses an ultrasonic sensor to detect motion when it is armed and uses a sound sensor to detect loud sounds such as the breaking of glass.

Prototype I was designed using an ELEGOO Mega board, LCD, Ultrasonic Sensor, buzzer, and a 4x4 matrix keypad. Fig. 1.1 shows the internal wiring used for prototype I. Most of the digital and ...

Ultrasonic Sensor; Buzzer; Arduino Mega (any model) Jumper Wires; USB cable for Arduino or 12v, 1A adapter. Ultrasonic Sensor Module: Ultrasonic sensor HC-SR04 is used here to detect the presences of ...

IR Sensor Pinout. The IR sensor has a 3-pin connector that interfaces it to the outside world. The connections are as follows: VCC is the power supply pin for the IR sensor which we connect to the 5V ...

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeti… ...

The authors propose a radar made with the ultrasonic sensor type HC - SR04, developed for Arduino. The novelty added by this paper is the development of specific libraries aiming to interface the ...

A simple Arduino based experiment was designed to measure the acceleration caused by gravity during the free fall motion of the object through air. This physics experiment can be carried out to ...

Historically, we’ve used IR and ultrasonic sensors but [Makers Mashup] decided to use an ESP32-Cam as a motion sensor in his latest animatronic creation. You can see a video of the device and ...
