USB power?

Is it possible to use this USB breakout board as a 5 volt power supply for your microcontroller projects? If so, then do you have to use a voltage regulator?
This is the result of a couple of tests with recently arrived microservos + programming + polymorph shaping technics + recently build G'Remote :-) Read more

Roboduino Tank Tread Base

We finally have our base for the Roboduino. I made a post to our site at: http://arduinofun.com/blog/2009/03/01/roboduino-base/


This is my first attempt to make a custom remote controller, and also my first customized Arduino.
After seeing this post made by ObbBot I wanted to try to make one myself.

I figured that if I purchase one remote controller it would be cheaper than buying two of these and paying shipment to Portugal.

So, ripping the guts from a game remote controller I get two joysticks, a couple of buttons, two nice motors and one small lcd.

This came up with the need of having the arduino permanently installed on the robots, I´m tired of having to remove the arduino from one bot to the other, and then rewire everything, and then reupload the code everytime I have a new idea, or everytime I want to show the bot to someone.
I followed the ITP Physical Computing tutorial, and it works like a charm, no I want to try to upload code with the FTDI cable, and If I have success on this I can start making my custom Arduino boards. :D

Can I get a little help ?

I need a little help with my Pololu Micro Dual Serial Motor Controller.... I am trying to use it with my arduino robot but I have no clue where to start code wise  ... where can I get sample code ... or even a guide on how to code for it .. I am sort of stuck on  this .... any help is appreciated greatly :)



Multi Temperature Sensor Reading and Recording Device

The video shows what it does, but I will explain again here. It establishes a serial connection. When one of the switches is flipped it starts collecting data from the temperature sensor once every however long I want it to be for how ever many times I would like it to take temperatures...or until it runs out of memory. When the other switch is tripped it shoots the data out into the debug window. The other sensors' data is random numbers It works better if you take data from a sensor that is actually connected :P. I have to get more of the sensors.

The new beginning

Hello Robot-creators!

It has been a long time since I was last active at this site... Mainly because I've been busy making stuff like this:


(Bidirectional 16-bit databus btw).

It's quite sad actually, now that I see all those cool robots that you've come up with, and all I have is stuff like that on the pictur above. I want to make something useful! Or at least entertaining... :)

Looks like cardboard...now it moves like cardboard too!!!

So far all I have is this cardboard prototype. I chose to make it out of cardboard instead of making a CAD model cause I thought it would be FUN! :p     Read more

Cool Arduino Library for driving servos!

I don't know if you guys already knew about these 2 very useful library to drive servo motors from the arduino, basicly you don't need to use analog write with an hexadecimal value to drvie the servo by PWM, you just write in degrees the angle and direction you wish the servo to go and it goes! 

Anyway here it is :

separating several sensor values

I´m starting a project were 2 Arduinos comunicate through wireless modules (XBee Pro).

Arduino #1 has two potenciometers and sends their values
Arduino #2 recieves the values like this:


Now I need to separate this values and assign each one to a variable.
But I´m stuck here.. any help would be apreciated!! 

Help with coding ...

So Iv'e got every thing but the Pololu Micro Dual Serial Motor Controller  hooked up and coded for (I mostly used other peoples code from the arduino site) but I but I do not understand what I need to do to get the motor controller to work code wise

I am using two GM9 (143:1 90 Degree Shaft) and the solarbotics wheels if that matters 


and this is the code I am using

alrighty saw this and thought it looked pretty damn cool


They are using the bbb arduino board as well.

Arduino and TSL230R ic light sensor


Found this great article(via the sparkfun site) on using a tsl230r light sensor with an arduino.

The guy actaully uses  a slick way to measure the pulses. This could be useful for other projects as well. 


As a side, the light sensor mentioned can be picked up at local radio shacks, for those of us that have them around. I think they are just a couple bux. Very worth getting.
