Hello guys, I'm new here and i just started leaning about 10 days ago. I still have no idea about most of the things.
I have a little back ground on programming, and i can do basic wiring; however i need to learn about voltages and resistors and how most shields work.
anyways, i have a little problem and i hope you guys can help me out.
i have bought a new 4X20 LCD screen, after hours of trying to wire it and stuff it worked .. However when i put the Ethernet shield on the top of my Arduino board and wire back the LCD accordingly .. i the LCD won't display anything, it just lights up. The pins i use for the LCD are below
LCD 4 (RS) to pin 12
LCD 5 (R/W) to ground (pin 14)
LCD 6 (E) to pin 11
LCD DB4, DB5, DB6, DB7 on pins 7, 8, 9, 10
I noticed that the LCD light is kinda dim, it not as bright when i connect it to the Arduino Board without the Ethernet Shield. I don't know if my Ethernet shield is not working probably or something, but the little red led power is on.
thanks for taking the time to read this, and please if you don't mind use simple terms as i'm really new to all this
Thanks you
