RGB Mixer – Processing to Arduino

It has been a long time since I wanted to control the arduino with processing and I tried a lot of libraries, and a lot of processes and I always felt that none of those were suited for what I needed. I needed something simple to implement and easy to understand, and because I am not [...]

easing servo movements

I’ve been working on this for a while and finally I have the courage to post the results.
I’m also testing the pololu micro serial servo controller in the hope I could achieve better results. One good thing the pololu controller has, is the ability to set the speed of the movement, I guess it is [...]

Servo Motor Hack @ AltLab

Here’s another way to hack a servo motor. This time Njay shows us how to do it, and it is quite easy. The code to use is the same for a normal servo, when you point it to the center (90 degrees) it will stop, than if you increment the angle it will start moving [...]

Talkie Walkie

Lusorobotica.com and EmbeddedDreams.com made a challenge to build a robot only with one servo, and this was what I came up with.
I used the sound sensor I’ve done a few days ago and a little paper-boat + a servo and a box and this is the result :)

This how the puppet works:

A hole [...]

Arduino Sound Sensor

Finally I have some time to continue with this investigation and great improvements were achieved with the circuit provided by Ant:  http://www.rev-ed.co.uk/docs/picaxe_sound.pdf
First here are the photos deleted by mistake from flickr:

The circuit

This is a closeup of the circuit, I´ve added a 10uF capacitor to stabilize the output signal (it´s the green cap [...]

G’Remote – Arduino based remote controller

27-August-2009 UPDATE:
My friend Gerhard from Germany asked me to build a walkthrough regarding the G-Remote, with part list, schematics and code. And here it is.  Enjoy  :D
___________________________________________________________________________
This is my first attempt to make a custom remote controller, and also my first customized Arduino.
After seeing this post made by OddBot I wanted to try to make [...]
