Arduino Sketch Question???

Hey, can anyone tell me why i am getting this error in my code as opposed to this other guy's code which is very similar?

I uploaded pictures of the bottom half of the code but i can provide additional information if needed.

I would love to know how to fix the error, Thanks!

I can't really tell without the rest of the code, but first thing to check is to make sure RELAY is defined somewhere.

Tony,
In the code you haven't shown us, look for an unwanted semicolon at the end of the line,
just before a '{' such as
void setup();
{

What version of Arduino hardware are you using? Which digital pin that supports PWM is the Relay connected to?

Are we to assume that your relay is connected as the standard LED? and will only draw 20 mA or less and have diode protection from back EMF? not to mention the need for pullup resistor of the proper value; internal or external!

int ledPin = 13; // LED connected to digital pin 13

void setup()
{
pinMode(ledPin, OUTPUT); // sets the digital pin as output
}

One more note: Providing a .jpg image of a sketch segment does not allow me or others to put the sketch into our arduino IDE and compile the sketch. I am just not that interested in retyping some sketch. Only a complete sketch would be suitable for testing changes that may solve the difficulty.

Hello Arduino guys!

This is the first time ever, that i am entering an arduino forum and there are so many options around here, i am not even sure that i am posting my question in the right place - if i am not, can you please explain or send me links or keywords for the correct pages? Thanks a lot!

Here is my question:

I am trying to build a robot, that uses the "Bluecontrol" android application.

Here is the Bluecontrol app on google play:

https://play.google.com/store/apps/details?id=com.gundel.bluecontrol&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5ndW5kZWwuYmx1ZWNvbnRyb2wiXQ..

The robot, called "MegaPed", building instructions and arduino sketch are detailed onwww.instructables.com, on this page:

http://www.instructables.com/id/MegaPed/

I have done everything exactly according to written and drawn instructions on that page, with only one change:

I have switched this BlueSMiRF bluetooth module, which is quite expensive:

http://www.amazon.com/SparkFun-Bluetooth-Modem-BlueSMiRF-Silver/dp/B004GTUI76/ref=sr_1_5?s=electronics&ie=UTF8&qid=1332730295&sr=1-5

With this JY-MCU Arduino Bluetooth Wireless Serial Port Module:

http://www.ebay.com/itm/251258723414?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

Now, my problem is, that after uploading the sketch - My android smartphone, is trying to connect with the bluetooth module, but shows that the module (called "linvor" on the smartphone screen) is: "Paired but not connected" - And i am unable to proceed and control the robot from the Bluecontrol application.

Maybe you can help me solve this problem or refer me to someone who might help me to solve this problem?

Thanks a lot,
Roi Neustadt.
