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 ...

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.

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object ...

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 ...

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [… ...

13 thoughts on “ 3D Scanner Using A Sharp Infrared Sensor ” othar says: December 21, ... I think with 1 steppermotor and A4988 arduino , tell me please if not , I am a beginner.

My Initial tests (using the regulated 5VDC power supply) found it works well enough for my needs. In my quick estimation, the Grove-mini PIR motion sensor module (v1.0) is a compact and cost effective ...

If the infrared heat levels detected by each aren’t identical, it’s because something has moved into an area visible to one sensor, but not the other. This difference means movement, at which ...
