// A hacky way to use a smart remote to control your Arduino remotly with Alexa. 

// Adding addition signals
// To add additional signals go to the broadlink app and pick any TV brand. Then test the remote in the app by pressing the on/off button. 
// Connect your Arduino to your pc and read out the serial monitor. You should receive the code. Test if the code is not used previously in the program.
// Test the code a couple of times to make sure it is always the same code (some signals are more complex and should not be used for this). 
// If you have an new code you want to use copy the code of the last signal and input your signal. 


// Import library. To install this make sure you are connected to the internet and in press Ctr+shift+i.
// Then you search for the library in the searbox 'IRremote' Install the one by Sherriff and press install.
