user71154: I am working on a RGB LED lamp project and this is the schematic for the circuit I managed to come up with.

I am planning to integrate a 27V power supply that powers both the Arduino and a Bluetooth HC-05 module, so I calculated the required resistor values as seen on the schematic. Would this design work? Is 27V too much for the Arduino or does the LED setup balance everything out?
EDIT:
I made an attempt to fix my mistakes based on the answers I received here and this is the new schematic:

This new model would use a 5V power supply instead. Would this fix all issues?

user4143: No. You will destroy the Arduino and the bluetooth module.
Firstly the Arduino needs no more than 20V absolute maximum - recommended no more than 16V.
Secondly a resistor is not a voltage regulator. It can only drop a fixed voltage when you have a fixed current. It only works with LEDs because they are themselves a fixed voltage.
Thirdly an Arduino output cannot power 6 LEDs in series. You get 5V out, but the combined forward voltage of 6 LEDs is between 12 and 18 volts depending on the colour.
