In some point in the life of every electronics hobbyist the need to make a clock is borned, in my case it was about a month after I soldered my first part on a board, but back then I didn’t have the right tools, parts andΒ knowledge to do such a thing. But after about 2 …
Arduino Processing Audio Spectrum Analyzer
In this Instructable I am going to show how to make a program in Processing that analyzes sound on your computer and sends data to an Arduino that controls an LED matrix to show the spectrum analysis. I will be explaining where to get materials, explaining the coding and wiring needed and providing example programs …
Plantduino Greenhouse using an Arduino
This summer I wanted to combine my two loves of plant science and engineering. Thus I am constructing my very own greenhouse in my backyard. I am an undergrad, and as any former student knows, this means I move around constantly, and I am not always around to take care of my vegetable garden. I …
Arduino Solar Tracker
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 Β When the stick on top is righted to the sun or the brightest point the four …
Tyco RC Arduino Robot
Wanted to make your own robot but couldn’t afford the fancy H-Bridge IC’s or etch your own PCB? Want a quick and dirty method of making your own wheeled robot? Then you’re in luck, but if you want to make your own wheeled robot AND have a quick and dirty wireless controller for anything then …
My Arduino WordClock
The initial project, and certainly the one to which many were inspired is that of Doug Jackson. http://www.instructables.com/id/The-Word-Clock-Arduino-version/ also inspired by http://www.highonsolder.com/blog/2011/1/8/arduino-word-clock.htmlΒ http://www.instructables.com/id/Sleek-word-clock/ Step 1: The Materials The list of materials for the board depends on how you plan to make the electronics, if you want an Arduino standalone or an Arduino UNO or 2009, …
Chicken Light Timer using an Arduino
The wife is into raising chickens and now that the daylight savings is getting near she wanted a way to keep the egg laying production in high gear.Β According to the material that she reads, chickens will maintain their egg laying production if they get 12 β 15 hours of daylight. I thought to myself, …

Auto Leveling Laser Cross using Arduino
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 Iβll break it …
Arduino 2-axis servo solar tracker
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 ΞΈ P = power generated by the solar panel A …
