A complete home automation system developed on ESP32 microcontroller using freeRTOS. The system is controlled wirelessly via Bluetooth with an android app developed using MIT App Inventor. A simple ...

Initialization: The servos are initialized and set to their starting positions. LDR Readings: The system reads the values from the four LDRs. Calculations: Vertical Adjustment: The average values from ...

Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

How it works: When something triggers the sensor, the Arduino records that moment as triggerTime in Line 23, and compares it with the current time based on conditions in lines 26, 29, and 34.

The massive quantity of electricity gets used in lights through roadways in India. Still, roadways remain empty for nearly all of the day after at night, with a handful of cars passing during the ...

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.
