Hi all i need a little help.
Is there any way i could control the turning on and off of an led by using the serial monitor?
Ie by typing in digital pin = HIGH then the led turns on
digital pin = LOW then the led turns off???
Im trying to be able to do this so i can try and build a GUI further down the line, but i want to encorporate all the hardwiring and code now.
Any help would be greatly appreciated.
