c++ - Arduino can't get my boolean to work -

i cant boolean work don't know i'm doing wrong it. take @ code , give me hint on wrong it? have tested different ways write without success. time boolean worked when put code under void loop. can't use there.

    #include <remotereceiver.h> boolean statusled1 = false;  void setup() {   serial.begin(115200);    // initialize receiver on interrupt 0 (= digital pin 2), calls callback "showcode"   // after 3 identical codes have been received in row. (thus, keep button pressed   // moment)   //   // see interrupt-parameter of attachinterrupt possible values (and pins)   // connect receiver.   remotereceiver::init(0, 3, showcode); }  void loop() { }  // callback function called when valid code received. void showcode(unsigned long receivedcode, unsigned int period) {   // note: interrupts disabled. can re-enable them if needed.    // print received code.   serial.print("code: ");   serial.print(receivedcode);   serial.print(", period duration: ");   serial.print(period);   serial.println("us.");    if (receivedcode == 353805)   {      statusled1 = true;   }   if (receivedcode == 352829)   {     statusled1 = false;    }   if (statusled1 = true) {     serial.print("on");   }    if (statusled1 = false){     serial.print("off");   } } 

if (statusled1 = true) { 

oldest gotcha in book. = assignment, == equality comparison.

also, don't compare against boolean regardless.

if (statusled1) {
