Hi, this is the code that I am using: char dataIn = 'S'; //Character/Data coming from the phone. int pinForwardBack = 13; //Pin that controls the car's Forward-Back motor. int pinLeftRight = 12; //Pin that controls the car's Left-Right motor. int pinBrakeLeftRight = 9; //Pin that …

:cold_sweat: here is the basic bluetooth slave code: /* BluetoothShield Demo Code Slave.pde. This sketch could be used with Master.pde to establish connection between two Arduino. It can also be used for one slave bluetooth connected by the device(PC/Smart Phone) with bluetooth function. 2011 Copy…

setupBlueToothConnection(); Seems like this function might have something to do with connecting the Bluetooth...

Yes but can you tell me why, when I'm using the first code the bluetooth shield does not connect to my phone? And also, i have already tried to incorporate the slave code into the other code, but all that happened was the car would spin around in circles continuously.

shahidzain67: Yes but can you tell me why, when I'm using the first code the bluetooth shield does not connect to my phone? Because you never tell it to? Nothing in the first code says "connect to this bluetooth device". Have you looked at the Master.pde code that the Slave.pde code alludes to? …

Right, so I have placed the bluetooth master code into the initial code. Still have some probelms like: 'check was not declared in this scope', 'RC_Car_with_lights.ino: In function 'void loop()', 'RC_Car_3_with_Lights:245: error: 'a function-definition is not allowed here before '{' token, RC_Ca…

void loop() { { char recvChar; while(1){ if(blueToothSerial.available()){//check if there's any data sent from the remote bluetooth shield recvChar = blueToothSerial.read(); Serial.print(recvChar); } if(Serial.available()){//check if there's any data sent from the loca…

Your check function is declared and implemented inside your loop function: void loop() { ... int check() { ... } } Your check function should be outside your loop function: void loop() { ... } int check() { ... } Using the Tools > Auto Format tool will make it easier to see thes…

Right, so I fixed the problems and uploaded the code to the arduino. The Bluetooth module is searching, however my phone is unable to find it. I think there may be a problem because the code has set the arduino as master, rather than slave.

shahidzain67:
as it connects to my phone easily using another code.

And you didn't think it would be a good idea to share the working code for comparison?
