need pointed in the right direction, if my project is possible

Former Member
Former Member over 12 years ago

I am newer to arduino, but i have some programming on it. I am a firefighter and want to create a light bar.

I am hoping that this project is possible for a near future completion date.

The project includes:

 

Arduino uno for pattern design and such. looking to use up to 16 3w LED from cree. its a small bar so nothing too much.

microelectronics to supplement the arduino for power as external power, step up if you will.

Bluetooth to turn lights on/off, hi voltage (3w for day use) low (1.5 for night use), change patterns.

solar panel (to create a self contained power (no wire running anywhere)

android app to control all the bluetooth

 

i could just buy a $400 lightbar but this would def be great if this is possible.

Please point me in the right direction on what to look at or such.

 

TIA

 

Matthew

    so matthew we will need less voltage thus increasing the chances of finding parts

    Yes you can run the same current from one driver through 2 LEDs in series (one after the other) if there is sufficient voltage from your power supply. You may need 3 or 4 volts per LED - so a 12V power supply would be more than enough to run 2 LEDs in series.

    Yes you can use the arduino to send LED status back though Bluetooth to either a PC or mobile device.

    now if you want the real time status the code will be edited and the bt module rx line will also be connected to send the host the status of the leds
