i need help in Bluetooth on freaduino

i dont understand how i connect the bluetooth to the freaduino i have the bluethooth that come in the MI primer KIT DE ROBOTICA can some1 tell me how i connect it

Do you have a link for the Bluetooth module?

The bluetooth is just an ordinary HC-05 and is connected to pins 0,1 on your freduino in more or less the same way as on a Uno. This is shown in the rapid guide _ Guía rápida item 7. Note that this image does not include a voltage divider on the Tx line, but it is good practice to do so.

I understand some of these kits have bluetooth modules that are set differently to the default 9600 baud, but I imagine there would be a note in the kit to that effect.

You might find the following background notes useful
