Led strip flashes when off
I've built the LED dimmer with the scheme on mysensors page. The only difference - i have 3 dimmers on pins D3,5,6 + MQ7 (A5) and DHT11 (D8).
Everything is working fine. But one of the led strips (not the longest one) flashes once in a while while switched off. 4-6 flashes of with different frequency and light power. Quite fast. Why is this happening? And how can this be fixed? Maybe some resistance to be added on the pin?
Could you share how you have wired everything and post your sketch? What does the debug output look like?
It goes off like it should. But than after 10 minutes or even more several flashes occur. Wiring is like on the mysensors page. The only thing under question should i interconnect the ground before the 12 to 5v converter and after? Or maybe add a resistor between the digital pin and mosfet
Are you using the development version?
In that case look for MY_LEDS_BLINKING_FEATURE, the LEDS are configured on pin 4/5/6.
Just define another pin (like A0).
Drove me crazy too.
No it's the stable one downloaded from the "API & Download" page. So i guess it's 1.5.4
In my sketch i found the
Is there a way to disable this completely or shall i define all 3 to the same unused pin?
//#define MY_DEFAULT_ERR_LED x
//#define MY_DEFAULT_TX_LED x
//#define MY_DEFAULT_RX_LED x
Well, uncomment the #define MY_LEDS_BLINKING_FEATURE and to be sure define all 3 LEDS to one (unused) pin. So you will make sure that is/is not the reason for the wrong behaviour.
