Utilizando um Arduino, três LEDs, um buzzer e um sensor PIR (Passive Infrared), criamos um sistema de alarme simples que detecta movimentações no perímetro da loja. Quando o sensor PIR detecta ...

Even though Attiny85 is fitting here, I opted for Digispark just because of its plethora of features like USB programming interface, on-board voltage regulator, and Arduino IDE compatibility. The code ...

Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor.

It uses a motion-detecting sensor (PIR sensor) to open or close the door which detects the infrared energy omitted from human's body. When someone comes in front of the door, the infrared energy ...
