Hi Everyone -
I am new to the Arduino and C++. I have set up a simple blinking 3 LED set up, after configuring this
I found a way to strap the common so as to not use all off the GND's on the board. I am also only 2 resistors and all the 3 LED's are working however my question is, by not using a 3rd resistor, do I have a potential in damaging the LED etc.
