I have a HC-06, I need to turn on a LED and Buzzer in a helmet, but the ARDUINO can not stay in the helmet, for this I want to try to communicate it by Bluetooth but I am new with all this arduino and wanted to know how I could do what. I am using a program with a sensor ULTRASONIC HC SR04 that activates the Buzzer and the LED to some distance but necessary to do it without cables that go from the arduino to the helmet, since as already I comment I want to do it by Bluetooth with the HC - 06

Your post is incoherent but it may be possible to use the bluetooth module to do this without an Arduino. This would be by using the STATE pin and/or pins not normally used with Arduino. I believe an HC-05 would be a better choice for this, as it is more versatile.
I'm not sure why you have a problem with this, as there are Arduino chips that are smaller than an HC-06, and probably use less power.
