This is the code to upload the arduino project
/*this car steering wheel audio control buttons is programmed as universal circuit.
 * This can be used to Volume up and down and, to back and next button. The both rotary encoder 
 * swiches are recommended for that purposes. and also more 2 switches are with the rotary encoders.
