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?

iPacemaker with Arduino

When we say “there are no limit for  Arduino”, here we have a project,  sent by [ladvine] in wich Arduino meets biomedic tech. The WiFi shield is the real application when they speak about Arduino. There is a long paper about it on this [website] that I suggest to visit to understand more this important project.

iPacemaker is an reprogrammable implant pacemaker with wireless connectivity.
A user friendly embedded web interface helps in changing every parameters of the implantable pacemaker. The important feature is the WiFi alliance complaint hardware which supports every wireless device to establish connection with the IMD. GSM connectivity can be used in absence of WiFi in remote areas helping in Telemetry.
Wireless protection in case of WiFi is enabled through WPA2 security with AES Encryption and Java Web interface which has inherent security capabilities. Shielding the GSM and WiFi antennas helps reduce unwanted patient radiations.
