Continuous rotation servos acting wierdly

As some of you may know I am in the process of making an R2-D2 like robot.

The base of the robot has two drive wheels and two castor wheels. The drive wheels are powered by continuous rotation servos.

The wiring is as follows:

7.2V Ni-MH 1800mAH battery > Regulated down to 6.6V > Powering the two servos > Grounds connected to Arduino > Signal cables connected to Arduino.

Rover 5 Motor Issue ?

Hello all

This is my first post in this forum and I hope you can help me. I just got a Rover 5 ( the 4 wheel edition) and the Dagu 4 channel motor controller.

Everything is connected with my Arduino Mega and I have no problems to control the motors and read the current amp value from the motors. I noticed that the motors are consuming up to 1.6 A and I think this is too much ? The Rover was not touching the ground and the default chain was mounted on the tire ?

Should I try to make the chains more loose ?

beginer in electronics needs to program

hi, im a twelve year old boy who is not an expert  AT ALL, but knows the basics

i've made bristlebots, speaker tones, dc motor cars  and other stuff

BUT

when i have to program  in arduino UNO i just copy other codes from other people

cause...  I dont know how to program at all!!!! i think arduino's language is c,and i don't know  how to program

 

anybody knows how to program arduino

and can give me a little tutorial about key words and etcetera like setup, delay, control of dc motors sensor etc...

Amanda Ghassaei’s Glitchbox

Amanda Ghassaei built this fun Arduino-powered noisemaker: The glitchbox is a sample-based drum machine used for live audio or MIDI sequencing. The buttons on the front of the instrument play back nine audio samples stored in its memory. A switch on top records and loops sequences of these samples. Once [...]

Faulty board?

 

Hello

I bought a card "Dual 15A Wild Thumper Arduino DC Motor Controller"

When I connect the battery (voltage OK) to the card the led "good battery" lights for a while and then goes off.

The "power" led is ON, the 5V output is ok, the corrent is about 40mA.

The board doesnt work.

Do I had to send the card to the seller or can I do  other controls.?

Thanks, Stefano

PS Sorry for my bad english language

 

H-Bridge only drives motor one direction:What am I missing?

(Perhaps I should preface this with the notation that NOTHING is working right today and I may just have gremlins.  That said...)

Charlieplexing

Hi.

Having got the processing/arduino serial sorted, I thought I'd have a go with charliplexing. I downloaded this library, and wrote a bit of code to try it. However, whenever I try to verify a sketch using it (including the demo sketch), I get this error;no matching function to call to 'Charlieplex::Charlieplex(byte [3], int)'. I've tried re-extracting the library, but with no success. Does anyone have any ideas?

If this library is broken, does anyone know of a better one for charlieplexing?
