Using the Mouse library, you can controls a computer’s onscreen cursor with an Arduino Leonardo, Micro, or Due. This particular example uses a pushbutton to turn on and off mouse control with a joystick. Cursor movement from the Arduino is always relative. So every time the analog input is read, the cursor’s position is updated […]

This instructable will detail how to make a switch that uses an arduino to sample light. When the light sample reaches a threshold it will trigger a relay that can be used to turn on/off a small appliance (light, radio, fan, etc…) The parts for this instructable can be ordered as a kit: Jameco Kit

In a couple of weeks, some students will visit my lab (Craft Tech Lab) to learn more about wearable technologies. I wanted to build a quick and simple application of a sensor and vibration motors for them to play around with and rough up. While this project could be made into a wearable mask, due

This project will show you how to create a computationally enriched puppet that can detect magnetic fields. The puppet (who I call Compy) has two very sensitive GMR analog magnetic sensors that are located in her beak, these sensors are read by an Arduino Nano that actuates a 3×3 haptic display (Figure 3) based on

I based this off of this really nice instructables.com post for building a water bottle boat, with some additions for obstacle avoidance and light-guided control. I used Arduino as a microcontroller, an ultrasonic sensor in the front, a few simple switches on the side of the boat, and a few light sensors on either side. See here for a

What is a solar tracker? A solar tracker can increase the efficiency of a solar panel by up to 100%! It does this by always keeping the panel perpendicular to the incoming rays of sunlight. here’s an equation to prove this: P = AW sin θ P = power generated by the solar panel A

So this Lazy Old Geek purchased a Laser Cross. I created a manual leveling Laser Cross to use for aligning stuff on my drill press: http://www.instructables.com/id/ManualLevelingLaserCross/ Well, being a Geek I decided to make an automated platform that adjusts automatically with an Arduino. Well, the picture may look a little scary but I’ll break it

What is does: It searches for the brightest light source like the sun. Step 1: How it works How it works: I’d made a sensor of 4 LDRs with sheets between them The withe stips are the LDRs When the stick on top is righted to the sun or the brightest point the four LDRs

The Just-For-Fun Sun-tracker using the Arduino and two servos. This device, along the lines of the most useless toy, is not so much for function as it is for fun. But as with many things, you can’t spell function without fun! This could easily be modified to rotate solar

So one of my last projects was adding a weather vane to my Arduino weather station. https://www.instructables.com/id/Arduino-Wind-Chill-Machine/ https://www.instructables.com/id/Arduino-Weather-Station-Part2/ This Lazy Old Geek decided to add a rain gauge to it even though we don’t get much rain in the high desert. Most digital rain gauges are based on something called a tipping bucket. Here is
