Amnesia =[

Adafruit is sending me a new one and prepaid postage to send the old one back. =]

I'll take a look at LiquidCrystal4Bit. Thanks!

It's not a LiquidCrystal problem. That's a separate issue I'll deal with later.

I tried the delay. From delay(100) to delay(5000), still does it display white boxes.

I got a replay from Adafruit. "Arduno Uno SMD?" I replied, "Yes, SMD." The waiting game continues!

Thanks again for all the help, guys! Diggin' the Arduino family!

Thanks everyone. I emailed Adafruit. I guess I'll keep working on my project and wait for a reply. =[

The Arduino has rubber feet on the bottom and on a wooden table.

I tried the light code. I think it is having the same problem. After I upload the code, the light is on. Unplug and replug back in, the light is off. Still think it's an NVRAM problem, but no idea how to remedy.

Not a contrast problem.

The standard "Hello World" example. When I upload the code, shouldn't it be stored in NVRAM? And when it restarts, shouldn't the Arduino load the code?

Hello! I received my first Arduino yesterday =] I googled but couldnt find a fix.

So I have an Uno and a 20x4 LCD screen from Adafruit. I followed the tutorial from ladyada very accurately.

Everything works fine. I am able to upload code, make it display text. The problem is when I remove the usb cable (powering it down), and reconnect it (powering up), the LCD displays white boxes on rows 0 and 3. I want it to run the code on start-up. I've tried pressing restart but it doesn't work.

It might do this by default. If so, How can I have it display the text when it powers back on?

Thank you =]

I'd be interested in one in the SF/Bay Area!
