With the above code if S1 is pressed LED1 is ON until S1 is released. If S2 is pressed LED2 is ON until S2 is released. The third "if" statement is different. Here we use a logical AND statement using a double "&" or "&&". A single "&" is a bitwise function and will produc...

Finally, close up your brackets from theifstatement, while statement, and main loop : 最后,为判断语句、循环语句和主循环敲上封闭的大括号。 Once you have programmed the board, open your Arduino Software (IDE) serial monitor. Make sure you have chosen to send a newline character when sending ...
the same as the assignment operator =, and the double equal sign is an operation used in the expression of the if statement to determine whether the expression can be true. The single equal sign is used to assign a value to a variable.在本段程序中也涉及到了if~else这个语句，下面来介绍if...

So if you have a statement if(irrecv.decode(&results)) replace it with if (IrReceiver.decode()). The decoded result is now in in IrReceiver.decodedIRData and not in results any more, therefore replace any occurrences of results.value and results.decode_type (and similar) to IrReceiver....
