Make your own, custom AUTONOMOUS SENTRY GUN! A Microcontroller Contest Finalist and Runner Up Winner. This instructable is out-of-date. For the most recent version of the tutorial, see the website . Cheers! This sentry gun autonomously tracks, aims, and shoots at targets, using: -An airsoft or paintball gun -A webcam to find targets -A computer to […]
The figures above shows the basic idea of any robot, where we have some inputs and output devices connected to the brain and some outputs controlled by the brain. In our case we will have the Arduino like the brain. The central Brain, controls all movements of the Robot. The sensors will do the monitoring […]
Step 1: Things you will need the images show you what you need. you will also need (but is not shown in picture soldering iron shrink tubes lighter 5 volt power supply usb cable (to program you’re arduino) info on the foamed pvc sheet This is a material that is very easy to cut […]
This instructable was designed for beginners in mind, but advanced users can easily adapt it to fit their needs and wants. It only uses a few common components, so you shouldn’t have much trouble putting this together. It’s a good waste of 5 minutes with a satisfying result (at least in my experience), and everything […]
I bought a solar powered garden light. The solar panel charges the batteries and when it gets dark the lights (3x LEDs) turn on until it either gets lights again or the batteries run out. It has a small amount of intelligence (turns on when dark off when light) but not enough! Time for some […]
The Arduino Yún is a curious addition to the Arduino family. There is a fairly widespread community surrounding the Arduino concept, platform and software. There’s another popular community dedicated to hacking and improving inexpensive wireless routers, which often run Linux. The Yún combines the two…it’s basically an Arduino Leonardo housed on the same PCB as […]
After making a 8X10 matrix a lot of people asked me about expanding the matrix to some thing bigger, and some wanted to write stuff to the matrix via a PC, so one day I looked at a pile of LEDs that I had leftover from a LED cube projected and I decided to make […]
For a party we were about to have I wanted a cool light display to use with my new Xmas present – an Arduino Uno. Having looked at the LED matrix’s here I wanted a bigger one that I could hang on the balcony. I also wanted it to interact with music and flash at different sound […]
I’m going to show you how to use your Arduino to control up to 12 servos at once with minimal jitter. Using a simple serial interface you can control the position of up to 12 servo channels. Up to 10 snapshot positions can be saved and played back at any time. Start up values for […]
This instructable will show you how to make your own arduino based watch that tells time using a matrix of LEDs. This is my first instructable, so if something is unclear leave me a comment or send a message! I was inspired by all the cool LED watches that I saw on this website: http://www.tokyoflash.com/en/watches/1/ […]
