sounds awesome man ;D yea i am sorry if i have been bothering u all this, i actually have a lot of knowledge of electronics, just not arduino 
im actually a electronics student and im used to working with PLC's and automated circuits the reason why i ask so much is because im afraid of bricking the arduino or some of the parts and i like having knowlegdeof what im working on 
okay so V+ is like 5v ? then i could maybe power the arduino without an external power source into the "vin" port ;D and ill try hooking up the signal to a PWM port and ofc common ground
