I need a bluetooth module that would allow me to use the following code in it as well (mainly the PWM stuff):
Code: Select all
const int pwmPin = 11;
const int TurnLightPin = 13;
//int delay_time = 1000;
int ledState = LOW; // ledState used to set the LED
unsigned long previousMillis = 0; // will store last time LED was updated
const long interval = 500; // interval at which to blink (milliseconds)
int dutyCycle = 0;
void setup() {
// put your setup code here, to run once:
//Change register values to adjust PWM frequency for PWM Pins 3 and 11: http://arduino-info.wikispaces.com/Arduino-PWM-Frequency
//TCCR2B = TCCR2B & B11111000 | B00000100; // set timer 2 divisor to 64 for PWM frequency of 490.20 Hz (The DEFAULT)
//TCCR2B = TCCR2B & B11111000 | B00000101; // set timer 2 divisor to 128 for PWM frequency of 245.10 Hz
TCCR2B = TCCR2B & B11111000 | B00000110; // set timer 2 divisor to 256 for PWM frequency of 122.55 Hz
//TCCR2B = TCCR2B & B11111000 | B00000111; // set timer 2 divisor to 1024 for PWM frequency of 30.64 Hz pinMode(TurnLightPin, OUTPUT);
pinMode(TurnLightPin, OUTPUT);
pinMode(pwmPin, OUTPUT);
Serial.begin(9600); // Default baudrate of bluetooth -- 9600 bits/second
Serial.println("HC-06 Bluetooth connected!!!");
Serial.flush();
}
void loop() {
// check to see if it's time to blink the LED; that is, if the
// difference between the current time and last time you blinked
// the LED is bigger than the interval at which you want to
// blink the LED.
unsigned long currentMillis = millis();
if ((unsigned long)(currentMillis - previousMillis >= interval)) {
// save the last time you blinked the LED
previousMillis = currentMillis;
// if the LED is off turn it on and vice-versa:
if (ledState == LOW) {
ledState = HIGH;
} else {
ledState = LOW;
}
// set the LED with the ledState of the variable:
digitalWrite(TurnLightPin, ledState);
}
//PWM Stuff:
while(Serial.available()){
dutyCycle = Serial.parseInt();
int pwmValue = (dutyCycle * 2.55 );
analogWrite(pwmPin, pwmValue);
Serial.print("PWMValue:");
Serial.println(pwmValue);
} // End of While loop for PWM
} // End of void LoopI was thinking about the nRF8001 but I read that the Adafruit Bluefruit LE UART Friend - Bluetooth Low is a better option?
Do I get one with UART or SPI? I'm not sure. My main goal is to be able to replicate the above code using either bluetooth module.
Is there a place where I can see the library functions and how to code using the bluetooth module?
Also, does the bluefruit iOS app have an option to make a custom controller layout? and have buttons send specific commands to the Arduino? (ex: if I click a button, I want it to send "A", if I click another button, I want it to send "B" etc..)?
I would really appreciate some help. Thank You.
