My problem is, I can find little reference to how to wire up LEDs specifically. Like, no basic schematics seem to exist.
Why the resistor in series with the switch.Not needed, and it will give a less defined LOW for a digital input pin.Just the resistor in series with the LED will do (with internal pull up on the pin).Unless you want added LED burnout info by using analogue pins.Leo..
Do I wire the LEDs to separate digital pins, or can I run them to the same ones I am using for the switches? Is there code involved in either instance? Can I be pointed to appropriate resources?
If this is to me.When the Arduino pin is at +5V, the LED is OFF.Pushing the switch (which connects to GND) causes GND current flow. The 240R will limit the output current to ~21mA
