<![CDATA[[SOLVED] SensebenderMicro restarts/crashes triggered by D3]]>I have a weird problem with a sensebender micro.
Loaded the standard sensebender sketch and all works fine.
Then I added a switch between 3.3V and D3 and initialized this with:
setup()
...
pinMode(MOTION_PIN, INPUT);
digitalWrite(MOTION_PIN, HIGH);
...

Now comes the weird part:
Whenever I press the D3 button, the sketch restarts. No matter if I sleep with interrupt or without etc.
If the serial console is NOT attached, it looks like the sketch continue to run.

I would assume some power issue, but for this test the board is powered over the USB-serial converter with 3.3V and everything else is working with or without opening the serial monitor in the Arduino Application.

Any idea what I am doing wrong?

According to this thread (https://forum.mysensors.org/topic/1573/my-generic-room-senser-sensebender-with-motion-and-light) I have tried to put a 25k resistor between D3 and ground, but without difference.

It is working better now.

You mean the issue has been solved?

It is working better now.
