It was a typo. i corrected it in the comment itself . Thanks |

T.Timer() needs to be outside that else if statement, otherwise it will not count down.

Thanks .The following code works but it appears to be counting 1 sec longer than 1 real second. Also , I want to know how can I display centiseconds or milliseconds displayed. Please help [code] #define ledPin A4 //indicator led Button setPin = Button(A0, BUTTON_PULLUP_INTERNAL, true, 10); unsigned long secs = 0; SevSeg sevseg; //Instantiate a seven segment controller object //Variables CountUpDownTimer T(DOWN,LOW); void setup() { sevseg.begin(COMMON_ANODE, numDigits, digitPins, segmentPins); void loop() { else if (plusPin.uniquePress()) else if (minusPin.uniquePress()) } |

Subtract 1 from Sec when you set the timer and multiply the milliseconds by 10 to give centiseconds
