Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion of a human body by the change in surrounding ambient temperature when a human ...

It should be a piece of cake if you program your Attiny85 chip (not Digispark) using your existing Arduino IDE with the help of one “USB tiny ISP (v2.0)” programmer. The software/Arduino sketch /* * ...

While PIR sensors can be used with Arduino and other microcontroller boards, ... Then, with a wave of your hand, or upon entering the room, you’ve got action.
