i made dimmer circuit.its working when control using ir sensor not working:(
plz me

if (results.value == up){
// if it's been @ least 1/4 second since last
if (millis() - last > 250) {
serial.print("dimming --> ");
serial.println(dim);
if (dim<127)
{
dim = dim + pas;
if (dim>127){
dim=128;
}
}
}
}

if (results.value == down ){

if (millis() - last > 250) {

serial.println(dim);

if (dim>5)
{
dim = dim - pas;
if (dim<0){
dim=0;
}
}
}
}
} // loop

there's not dimming @ all, ir receiver doesnt work code..

do think can me?

thank sooo much!

marc:)

what see when print results.value ?
