LED (Widget) is very dim [SOLVED]

See subject and attached screenshot. For some reason the leds are really dim, in this case the MNT led is on and its hard to notice. Is there a way to get it brighter?

UPDATE: I case its not clear, I mean the WIDGET LED in the app (see screenshot)

System is Android on Galaxy S8 Edge.

Thank you!

CAN U POST THE PIC OF THE LED??? to see how bright is it glowing and basically to see if it is flickering.

also check the led with the 3.3v batt if u have one and see if ur LED is working fine with just the batt. attached

Apparently I wasn’t very clear: I mean the ‘led widget’ in the app.

Share the code you are using for the LED Widget. The LED Widget brightness is adjustable.

I dont use any code I just added it to the project. But from your answer I gather that I can update the brightness through the arduino code, didn’t know that.

If no code, Then what determines if it is on of off?

this code:

void updateBlynk(){
  if (blynkUpdate){
    Blynk.virtualWrite(V3, targetT);
    Blynk.virtualWrite(V4, currentT);
    Blynk.virtualWrite(V5, heatOn);
    Blynk.virtualWrite(V6, valveMaintenanceCycle);
    Blynk.virtualWrite(V7, errorFlag);
    blynkUpdate = false;
  }     
}

V5,6, and 7 are the leds

so the widget (led button) has a very low brightness??? or ur actual hardware led??

widget led.

I suspect that in this case HeatOn, valveMaintenanceCycle and errorFlag are either 1 or 0? That is most likely where your problem is.

look over the DOCS for the LED Widget. I’m sure you will see the issue.
LED Widget

If you share your full code, I may be able to give you a better example.

If the value that you’re writing to the LED widgets is small (1-50 for example) then the LED will be dim.
You need to write 255 to obtain maximum brightness.

Pete.

your assumption is correct. I see now what I have to do. Thank you for the very swift replies!!

@PeteKnight: I gathered that from the documentation.
Very helpfull forum this!!

No Problem. Glad we could help.

Happy BLYNKing!

For good measure, here the updated code:

void updateBlynk(){
  if (blynkUpdate){
    Blynk.virtualWrite(V3, targetT);
    Blynk.virtualWrite(V4, currentT);
    Blynk.virtualWrite(V5, heatOn*200);
    Blynk.virtualWrite(V6, valveMaintenanceCycle*200);
    Blynk.virtualWrite(V7, errorFlag*200);
    blynkUpdate = false;
  }     
}
