Arduino nano 33 
  • Turning on the light
    anode of LED –> ground 
    catsode of LED –> resistor(220 ohm) –> power

  • Blinking LED
    anode of LED –> ground
    catsode of LED –> resistor (220 ohm) –> digital pin 

  • Potentiometer (variable resistor)

One LED burned while testing. Short circuit happened when turn all the way close-wise. 
How do I prevent this though?
Data sheet of the potentiometer used.

  • Reading a Potentiometer (analog input)
