Steve Grand’s "Creatures" Neurons simulated on Arduino Uno

Hey everyone, it’s me again.

So today I’ve been working on a project: recreating Steve Grand’s artificial neural networks from the old “Creatures” games on Arduino. Why, you ask?

Connect 2 speakers to arduino uno

Hi everyone,

 

I'm sorry to bother with such a basic problem but I'm trying to connect 2 speakers ( a piezo and a 8 Ohm speaker ) to an arduino uno to play some tones. The fact is I can play tones with only one of them at a time.

 

 As a beginner, I don't know it's my code wich is wrong or the breadboard layout, so I uploaded here both of them hoping that someone can show me the light !

 

THX EVERYONE !

Here is the code:

int speakerPin = 8;

int speakerPin2 = 9;

 

int length = 295;

motorcontroller board [FIXED]

Hello

I am trying to build a segway, I know how I am going to make it, but I have been struggling to get the motorcontroller to work for days now.

I attached an accelerometer and a motorcontroller to an arduino uno. When I tilt the accelerometer 2 indicatorlights on the motorcontroller change, so this signal must be right. But when I measure the voltage at the motor output I get only 10-60 mV.

I tried using more and using less Volt (5-15 V) on the m.c. board itself. (I attached it to an old model train transformator)

Please Help

Issue with Arduino Uno/Motor Shield r3 - Code or faulty power connection or both?

First post and second robot build (first was the Build your first robot from the Popular Mechanics magazine).  I am having an issue and seeing if I can get some assistance.

Rover 5: how to determine direction with a compass (LSM303)

I recently bought a Rover 5 and an Arduino Uno and made my first sketches. My goal is to let the Rover drive standalone in our livingroom, avoiding objects, childrens and pets ;-).

Arduno Home Robot

Hello, I am planning on making a butler bot or home bot what ever you want to call it. It is going to use an arduino for a brain. Anyway I was wondering about what I should make it do so I am asking you to be creative and tell me; If you had your own robot that could do anything what would it do?

Be creative any Idea is appreciated.

Need help with a major proble,

Hi, 

I am trying to build a toy car with an arduino. I am using a tamiya twin motor gear box ( as seen on http://www.pololu.com/catalog/product/1680). This is connected to a track set.
