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

Former Member over 11 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

hi i think this is possible with a bunch of relays
you can look it up on google for solar you will need batteries to run it at night
and for bluetooth take the arduino bluetooth library

i was thinking of having the solar panel go into a small rechargeable batter (?) to run it at night, to store the energy until use.

yes then you can
depending on your battery type you will need the solar panel

you will need to use the battries all the time cuz the panel won't have enough amps or volts

Since we will be receiveing the data through the module and then in turn sending it to the arduino board we only need to use the TX pin on the module. Run a wire from that pin to the RX pin on the arduino board. The Led is controlled through PIN 2 on the arduino.

The important aspect here is the baud rate - make sure it matches the baud rate of your module - check the datasheet or use AT commands to do it.

const int ledPin = 2;      // the pin that the LED is attached to
byte serialA;
void setup()
{
// initialize the serial communication:
Serial.begin(19200); //baud rate - make sure it matches that of the module you got:
// initialize the ledPin as an output:
pinMode(ledPin, OUTPUT);
}

void loop() {

if (Serial.available() > 0) {serialA = Serial.read();Serial.println(serialA);}


      switch (serialA) {
    case 1:
      digitalWrite(ledPin, HIGH);
      break;
    case 2:
      digitalWrite(ledPin, LOW);
      break;
    case 3:digitalWrite(ledPin, HIGH);
      delay(100);
      digitalWrite(ledPin, LOW);
      delay(100);
     default:

      break;
}

}

hope this helps
i'll try to post the main circuit also including the light bar design

try making this neater than i did
sorry i could not vary the wattage of the leds
if you already have an arduino
just buy a new atmega328p,put in in your arduino program it
remove an put it in your project wire it all up according to the datasheet on the arduino website.
you will need to put a 16 mhz crystal and two 22pf caps to pins 9,10
just to be on the cheap side
use a vreg that can regulate from 50 volts not 35 or you'll fry it

if you are satisfied please mark this as a correct answer
man! that was tiering
