Have you ever seen a radio without an antenna? I see three wires going to the transmitter. It is not clear what those three wires connect to on the Arduino.

i have conected the antennas, they are 13cm long, but they arnt very clear to see on the picture because the coating is black just like the desk.. if u look above the breadbord on the first picture u can notice the striped silver wire.

i am drawing the schematic already, ill post them a.s.a.p.

So at one point, you had it working, but you mentioned earlier that you had the polarity flipped on the transmitter. So have you tried the example code again to make sure that the transmitter wasn't fried?
