Arduino Bluetooth Relay 4CH App is android application which is used to control 4 channel relay module via Bluetooth with Bluetooth serial communication.
You will get a bunch of numbers followed by 'usecs' or 'usec'. Make sure you have copied the signal you want into a word pad for easier reference. It will look something like this: 500 usec, 300 usec 600 usec, 1200 usec But there will be a lot more numbers than that. Now in the program you will see this quite a few times: delayMicroseconds(); pulseIR(); You want to take the first number and put it in the parentheses in delayMicroseconds('here'); value And you want to take the second number from the same line as the one of the delayMicroseconds(); value and put it in the parentheses of pulseIR(); value. Example: Say you get this on the serial monitor: OFF ON 1660 usec, 580 usec 1640 usec, 560 usec You want to put the corresponding values in their corresponding areas. Such as: delayMicroseconds(1660); pulseIR(580); delayMicroseconds(1640); pulseIR(560); It is pretty damn easy. Once you get the codes you want, open the IR_SEND.pde file in the Arduino program and then put the values that you got from the serial monitor between the parentheses doing it the same way I showed you how to do it. The next step will show an example of how I did this with a Comcast remote.
