// Definition of the PIR sensor pin, Buzzer pin and LED pin goes here. int pirSensorPin = 2; // Connect the PIR sensor to digital pin 2. int buzzerPin = 3; // Connect the Buzzer to digital pin 3. int ...

As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion ...

The PIR module actually consists of a pyroelectric sensor (looks like an old metal transistor with a black window on the top), which generates energy when exposed to heat, and it’s tied in closely ...

And the other pins are generally connected to the Digital pins and in the PIR sensor, connect the ‘OUT’ pin to the Digital Pin no. 8 (you can choose other ports too, it’s totally your choice ...

VCC - Provides power for the module, Connect to the 5V pin of the Arduino. GND - Ground Connected to Ground pin of the Arduino. SCL – Module output (HIGH (3.3 V) motion detected/LOW (0 V) idle). CDS – ...

Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list.

Working from home with regular video meetings has its challenges, especially if you add kids to the mix. To help avoid embarrassing situations, [Charitha Jayaweera] created Present!, a USB device t… ...
