In the following tutorial, directions are given for creating a single node for the DoHas (Distributed Optical Harvard Architecture System). After constructing two of these nodes, a small distributed computer can be implemented which uses one node for sending instructions, mimicking input and the instruction set to manage it, and another node which will act […]
I’ve gotten hold of what I assumed was a compatible 16×2 LCD screen with my Arduino board – it’s a Powertip PC1602F and uses a compatible display driver for the Hitachi HD44780 display chip. This is essentially what the Arduino LCD libraries are built around, so when I failed to get a display this is […]
It all started as a weekend project with my kids and soon enough I got sucked into a 4 month project with their school ! The idea was to get a small group of kids aged 6 to 9 to participate to a robotics contest (http://www.eurobot.org/eng/index.php). It was a fun journey and they did really […]
If you haven’t noticed, as soon as you clicked into this instructable, you are now following me if you weren’t already, you Favorited the instructable, and you voted for this instructable in all contests it is entered in. Then the buttons all dissappeared. It’s okay though. If you really want to, you can still go […]
The project consists in a Arduino that gets the speed of the bike from a dynamo and it controls a laser which points always to the point where the bike is gonna stop if it continues going at the same speed. Used Hardware: Arduino mini Atmega328 Laser Servo Dynamo Battery pack 4 x 1,5 V […]
This system is upgraded version of previous project… You will be able to track your car after you build this system, you will call the device then it will send you an sms which includes LAT, LON and Google Map link for just one touch to see where it is. Before you start to build […]
Doodle Bot is a very simple beginners robot that can write messages using white board markers, jumbo chalk or crayons. The kit comes with all parts including an Arduino compatible controller and a screwdriver. You will need to supply 4x AAA batteries and a suitable USB cable to program the robot. A large, full colour […]
This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here. You can use bit-shifting as an alternative way of creating “music”. This principle enables you to squeeze as much processing power as possible out of the Arduino while creating novel and interesting […]
I’ve started to delve into Processing and passing values between Processing and Arduino. If you’re wondering what Processing is, basically its an open source programming language for vizualising data that can interface with Arduino either by reading values/ pins or by setting them. Just remember that they are 2 very different things and require 2 […]
UPDATE 02/13/11 : Voting has started for the Sparkfun Microcontroller Contest. Please VOTE for me! UPDATE 02/26/11 : I won a second prize!! Huzzah! Thanks for all the votes guys! UPDATE 03/17/11: I would love to win a Laser cutter in the Epilog challenge as it would help the small DIY community in Calcutta, […]
