i got two hc-05 to control my robot with
but i cant realy seem to be able to connect the arduino with it!
i wrote a simple code about getting the chars i type on the computer to send it to the arduino and from the arduino to the module and then gets the respone back from the module to the computer
but i tried many times to connect it with it and it didnt seem to workout
the rx of the module is 3.3 level so i made a voltage divider with 3 10k R but how many times i try it doesnt work
