Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

One doesn't need more that about 1000 Hz sensor fusion filter update rate to get optimal performance from 6- and 9-axis motion sensors, but the power consumption is proportional to the microcontroller ...

The Etch a Sketch toy has gone more or less unchanged for over 60 years, but if you’re handy with a soldering iron you can build an upgraded version that swaps aluminum powder for glowing LEDs.

It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards whi… ...

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 ...

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 int motion_1 = 2 ...

How it works: When something triggers the sensor, the Arduino records that moment as triggerTime in Line 23, and compares it with the current time based on conditions in lines 26, 29, and 34.

You'll definitely need some gear for it—the Arduino for one, but also a PIR motion sensor, not to mention the (cleaned and rinsed!) Raid Power Sprayer motorized spray bottle.
