Bluno + RGB + Iphone
fernangutiglesias 2015-03-15 04:07:37 3710 Views5 Replies Hi guys,
I've been doing some projects with my Bluno for a short time, but now I'm trying to work with the Bluetooth and my Iphone. And now, I have some problems with my code.
I'm trying that my Bluno gets a word like "Red" and it turns on the red led of my RGB. It works perfectly using the app Bluno Term, but if I send a different word that doesn´t appear in my code, the code fails.
This is my code with the last test that I tried:
I have another question, Could I use the color wheel of the Play Bluno app without a Bluno Accessory Shield?
Sorry, but I'm a newbie and I have a lot of stupid questions...
Thank you!

Code: Select all
int RED = 2;

int BLUE = 7;
char letter;
String word;
void setup()
{
Serial.begin(115200);
pinMode(red,OUTPUT);

}
void loop()
{
if(Serial.available() > 0)

word += letter;
}
if (word == "Off")
{
setColor(0, 0, 0);
Serial.println(word);
word="";

void setColor(int redc, int greenc, int bluec)
{
analogWrite(RED, redc);

You are right leff, I had a problem with the if else statements. I discovered the problem and I repaired it.
Thank you so much for everything.
Now I have to find the way to use the Play Bluno App or another similar with a single RGB Led... fernangutiglesias

Oh, the if-else syntax you used in ur sketch is not properly, you could google it. It should help. Leff

Leff 2015-03-21 02:32:15 Hi,
1 Yes, that's my problem. If I send any word different that I put in my code, the arduino doesn't understand it, and the word makes that the string word contains new words every time that I send any word.
Can you help me or give me an idea about how to repair my code??
2 I'm not connecting any Accessory Shield, because I'm ussing a simple RGB LED. fernangutiglesias

fernangutiglesias 2015-03-17 22:34:29 1 if you send 'blue', your RGB should be blue, right? but if you send any word not in the code, sure, the arduino won't recognize it.
2 as long as you wire all devices correctly, it will be ok. Maybe the accessory board you used is for expansion function, so it's not a must.(i am not sure which Accessory Shield you are using ) Leff
