Hello everyone.
can someone help me through this.
else statement is executing even though the if statement is true.
i am usin serial montior for comunicatin with arduino and if type a command which is true for my programm its excuteing the if statemnt which is true and as well as else statement which i dont want to happen.
below is the code and picture od serialmonitor.
Thank you in Advance
