Arduino based Fire Alarm – Circuit and Working Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...

They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, with students caught in the act of popping balloons. The goal here was to keep things as simple as ...

Circuit Diagram for Sound Sensor Module. The schematic diagram for the Sound Sensor module is shown below. The schematic itself is very simple and needs a handful of generic components to build. If ...

The Echo pin can output the sound wave’s travel time in microseconds, e.g., the sound wave can move for around 294 seconds if the object is 10 cm from the sensor and the sound speed is 340 m/s (0.034 ...

Step 7: Working Principle Of Autonomous Food Supply System. The working principle of the food supply system is very simple and the most vital component in this circuit is the Real-Time Clock Module ...

The heart of this project is Arduino Uno which is the microcontroller used in this project. The PIR sensor will sense any motion in the range of 6 meters and if the motion is detected, it will send a ...
