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 ...

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 /* * ...

PIR Pin “+” connects to Arduino +5. PIR Pin “-” connects to Arduino gnd. PIR Pin “out” connects to Arduino Digital 2. Here is the Arduino code for the Parallax sensor ...

Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

Makers and developers looking for a motion sensor Arduino Shield, are sure to be interested in this new ICU-Duino which has been created by Patrick Thomas Mitchell based in Ottawa, Canada ...

Hot glue the motion sensor to the hole you drilled for it. Feed the wires through their respective holes and attach them to the Arduino and the power relay. Reattach the enclosure’s top cover.
