Hi.
When i connect my HC 05 bluetooth module to my arduino UNO then connected it to my smart phone by a simple application that sends a one byte number, the arduino UNO recieves it but 1 as x and recieves 2 as € ofcourse upon programming it to light a ledPin it doesn't light it up because of the x and € signals ... does anyone have a solution to that problem and thank you
That's an image of the code and the corresponding serial monitor upon sending 1 and 2 from a smart phone
