After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

Using motion detectors and an Ardunio you can add a little extra wow to your Halloween displays ... Here is the Arduino code for the Parallax sensor. int motion_1 = 2; int light_1 = 13; void ...

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

A motion sensor activates the light when it detects something moving within its field of view. Photocells work with a resistor that changes its conductivity based on how many photons are hitting it.

I set up my $25 WyzeCam v2 with the PIR Motion Sensor and Sensor Bridge accessory to catch some hummingbirds feeding. I can't use video motion detection because the feeder is constantly swaying in ...

When a finger or other object touches the surface, it causes the IR light to scatter in many directions. Some of this light is directed down into the screen, towards an array of 64 IR sensors.
