Global variables use 71 bytes (3%) of dynamic memory, leaving 1977 bytes for local variables. Maximum is 2048 bytes.
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x68
I have tried changing definations, ports and my shorts. This program did work sort of once. Got good text with some gibberish. Got proper screen brightness once. Program will complie. Will not load.
Any ideas any one?? Thanks for any help.

Try changing the Processor to Old Bootloader in the IDE Tools menu
Hi,
Done that but I'll try again. I'm setting here watching -no change.

What is connected to the Nano, particular the Tx and Rx pins.
Which program?
On the same Arduino?
What is the project that you are working on? Please give a complete description and mention all components that you use.
Does the L-LED flash quickly when you press and release the reset button?
One flash or a few flashes?
Hi, I didn't realise there was anybody to assist my confusion. O.K.
Here's the sketch:
And the schematic:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x2b
I can see text on the LCD but it's buried in the back light glare. That's all that is connected to this project.
Another question comes to mind: should I be answering your questions in the Arduino Forum?
Thank you for any input.

Hi, I didn't realise there were folks who would help. Thanks in advance
I'll try this again. Attached is the sketch
And the schematic:
When plugged in, the green light comes on and is steady. When uploading sketch, the red light blinks 3 or 4 times and goes dark. The IDE says it's uploading for a long time 3 - 5 minutes and comes up with:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x8f
I can see lettering in the LCD but they are hidden in the LCD glare.

Good Morning,
Nothing is connected to Tx or Rx
Thanks for the question.

Looking at your picture I do not see a contrast adjustment pot. I believe the display needs about 5V for it to light up, the data sheet will let you know.
Please post a link to the exact Nano that you bought.
Hi,
The box says NANO BOARD. I purchased from Arduino and the board says NANO.

Hi,
The LCD background lights and once I got readable gibberis bright and white. Since then I can see text in dark lettering (very dim) against the background glare. Only readable on an angle to the face of the LCD.
Keep the questions coming folks, We'll figure out where I screwed up. Thank you for your assistance.

That sounds like a contrast problem. The pot should fix that.
Good Evening,
OK I'll put a pot in brightness circuit. Will let you know tomorrow
Thanks
