An Automatic Door Opener System is a project based on PIR Sensor and Arduino, which automatically opens and closes the door by detecting a person or object. You might have seen Automatic Door Opener ...

In the microcontroller era today, Arduino ... at its sensor input port. As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an intrusion ...

The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something ... Because an on-board “user” LED is wired to P1 of Digispark by default, you ...

Get close enough to this raven and you’ll set off the PIR sensor ... 12-volt power LED. This bird’s brain is an Arduino Nano, which is protected from the 12V supply with a boost converter.

Once your code and hardware are ready, connect Arduino to the laptop and upload the code. After that, open the serial monitor at a baud rate of 9600, and make some motion in front of the sensor.

With Arduino, this can be a simple and low-cost reality ... The lights in this project had a solar panel, rechargeable battery, control board, PIR sensor, photoresistor and three LED panels. Let's ...
