Problem Getting A Working Connection Between Board and Computer

Development Tools Uploading
1

I've been trying to make a hexapod, and have the coding and hardware done. However, I cannot get the code off of my computer onto the Arduino Nano I have installed to the remote or the Arduino Uno I have installed into the robot.

Problem 1). The Nano consistently receives the error message avrdude: stk500_recv(): programmer is not responding and then proceeds to try to reconnect ten times before quitting. Yes, I have made sure I selected the correct ports, boards, and processor under Tools.

Problem 2). The Uno receives one of three errors. The first is the same as the Nano. The second is that the code is not compilable for the Uno, which is obviously false because it will compile it half the time. The third result is it "uploading" only to fail to perform when I turn on the robot. I have checked and rechecked the code and am sure it is right.

For both of these boards I went into the WiFi101 Firmware Updater to test the connection, and have never received a successful connection, although the boards are clearly receiving power.

The code for both programs are decently long with the remote programming being around 200 lines and the robot being around 1100 lines, so I won't put them directly in this post. I will attach them though.

There was a boards update that affects the Nano; not sure if you have it installed but in that case you should choose the 'old bootloader' and it might solve the problem.

Post the full error message when the compilation fails.
Is there anything connected to pins 0 and 1? That can interfere with uploads via USB as the onboard TTL-USB chip uses the same pins.

You don't say which board you're using. As the opening post was about Nano, did you try the suggestion.

And do not hijack other peoples threads; it's considered impolite and you should have started your own one. You can report your post (see link under your post) and ask it to be moved.

And cross-posting is even worse; where do you want us to waste our time? I reply here, somebody else replies elsewhere and later on one of us wonders where their reply went.
