So, you’re thinking about getting an Arduino starter kit, but wondering if some basic LEDs and resistors is going to be enough to keep you busy for the weekend? Probably not.
Here are another 8 cool electronic Arduino components you might want to just add to your basket, along with some great ideas for what you could do with them.
Servo MotorThe kind of motors you and I may be familiar with are ones that simply turn on and you can perhaps vary their speed. They take a while to get going, and to slow down. A servo-motor on the other hand can give precise control over the speed, direction and amount of rotation. They’re used heavily in robotics, but a basic servo-motor isn’t at all expensive. You should be able to pick up one up for about $10-20.
Potentially Awesome Project:
- Rotating imitation turret with pew-pew sounds for defence against wandering neighborhood cats!
Obviously, any aspiring hardware hacker needs a laser or two in their collection. Prices will range from about $20 for a 0.8mW red laser module using which you can only see the beam at night with a smoke machine… to about $200 for this 500mW Blue laser, which is clearly visible, and very much guaranteed to burn stuff.
Â
Potentially Awesome Project:
- This is an optional upgrade to any basic pew-pew turret cat-defenses you have.
- Combined with a camera and laptop, an automated balloon popper could be quite fun at parties.
Warning: Lasers are genuinely dangerous, no kidding, so make sure the party you take your balloon popping robot to isn’t that much of a good friend because you may never see them again. Also if you can, provide advance notice that medical insurance is required for all attendees.
These are really popular right now, and for about $100 you too can get a full robot base to build upon with 4 independent drive wheels and optional tank tracks. Whatever you’re building â€" just think how much cooler it’s going to be on wheels!
Potentially Awesome Project:
- What part of mobile laser-turret cat-defense system do you not understand?!
- Or, how about building your own little drummer robot, that runs around looking for things to drum and samples it all to playback later.
A 2D array of LEDs â€" these can a little trickier to control than standard LEDs but are a natural progression that gives you another dimension to play with. They cost around $30.
Potentially Awesome Project:
- Build your own version of a British speed-camera smiley-face sign for pussycats that dash across your garden far too quickly. Here’s a real life example I took on the road near me, though it’s designed primarily for cars and not cats.
Quite expensive for LEDs ($20 each), but you can program a full gamut of colors dynamically. You’ll need to learn a little more about the various data protocols on the Arduino for this, but that’s a good thing.
Potentially Awesome Project:
- Mood-lighting galore, basically. This guy used 6 of them to create a home made version of those TV backlights, which is next on my list of stuff to build.
- Real life Nyan-Cat? You could strap a few of these onto a white Persian, and let the rainbows commence. Note: Must be white. The projection capabilities of darker cats results in disappointing rainbows.Â
$50 will net you the ultimate in communications devices for your project, allowing your device to communicate over standard WiFi networks and through to the internet! Open your device to the world.
Potentially Awesome Project:
- Aforementioned turret could be easily modified to auto-Tweet the number of shots fired at frisky feline trespassers to your @gardenprotector Twitter account.
- Why not buy the domain kittykillers.com and allow random internet users to remotely control the firing mechanism. Note: network lag may cause a significant decrease in shots-taken to kills ratio.
These are actually an IR led and sensor in one self-contained package, and they work by firing a infra-red beam of light out and measuring how long it takes for it to come back. Useful in any kind of robotics projects for obstacle avoidance, and only about $20.
Potentially Awesome Project:
- Upgrade your tabby-turret with a close range warning mechanism that emits high frequency sounds if aforementioned cats comes too close to investigate and laser is otherwise inoperable.
- Automatically turn off your computer to prevent eye-strain when your face gets too close to the monitor. Could be annoying when your folks come round though â€" I don’t know about you, but mine always feel the need to squish themselves to within an inch of my monitor, despite the fact it’s a full 27″ across.Get some glasses, mum.
The LilyPad series of Arduino components are designed to be as flat as possible with large holes on the board that allow them to be sewn into clothing. This particular $20 LilyPad brand component is a flat vibration motor, which, I quote:
Works great as an physical indicator without notifying anyone but the wearer.
Potentially Awesome Project:
- No idea â€" I can’t think of a single possible usage example for a vibration device which can be discreetly sewn into clothing, but I’m sure you can come up with something. Did I mention it’s also washable?
Well, that’s enough cat cruelty for one day. If you enjoyed this post, please share it with your friends, because it let’s us know that you like this article and want more like it. Also, do post in the comments if you can think of any other possible ways in which I could keep the cats out of the garden awesome electronics project ideas or fun components I’ve neglected to mention. Thanks for reading, and best of luck with your hardware hacking.
