 Bigger Bigger  Smaller Smaller  Reset Reset

Dear forum

I'm experiencing strange behaviour nomatter what program I test. To keep it simple:

1) I upload the pushbutton example without wiring any external devices
2) I wait
3) The control LED instantly lits up! (I swear didn't push any buttons!)
4) If I touch digital in 3 (set up in the example) the control LED light goes out
5) Sometimes when I move around the table the control LED flickers.

What can be wrong? I'm really lost.

The digital inputs have such large resistance that if you do not tie them high or low with a resistor they will float in the middle. Their level will depend on how many electrons are trapped on them. This is easily changed by a static charged touch.

Wire up the switch and resistor and everything will be good.
