Outputs
Outputs can be used to power LEDs, relays, optop-coupler, gates and much more.
The selected pin will be HIGH when the LED/Gate ist on. Otherwise it will be LOW (0 Volt).
You can reverse this by selecting "Output rev." instead of "Output" during setup.
Connecting an LED is really easy:
Connect the kathode (short leg) to GND.
Connect the anode (long leg) to the desired pin via a 220 Ohm resistor
It should look like this.
