Powering a 16x2 LCD Screen? Answered
Hey all I am relatively new to the Arduino platform and learning as I go. I have a 16x2 LCD screen that I am trying to learn how to use. I hooked my positive lead to pin 2 and the Ground to pin1 and nothing lit up. I then hooked a potentiometer up to pin 3 to try and adjust the contrast still nothing lit up. Does this mean my LCD screen is broken? I haven't sent any code to it so I am not expecting it to "say" anything, but i thought when the power was on it would at least light up? Please let me know if i need todo anything else to make it light up or if I need to buy a new LCD. Thanks!
