Hello,
I was wondering if anyone encountered the issue of having troubles to upload sketches to the board.
I can't upload any sketch to the board without getting the following error message:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x83
avrdude: stk500_recv(): programmer is not responding

This is what it looks like:
I followed the steps in the Assembling Instructions Google Doc and think I chose the right board, Processor and Port. I tried different USB cables and searched the internet but wasn't successful in solving the issue.
I would greatly appreciate any ideas or help.

Only click upload button once and wait for the IDE to compile and upload. It may take one minutes (10 seconds compiling, 30 seconds uploading, 20 seconds validation).
You mentioned that the yellow LED blinks slowly. It may be caused by:
1. You're not powering the board by battery. In that case, if the servos were commanded to move, they will draw large current through USB, and trigger the protection on your computer. It will disable the corresponding USB port. You have to switch to another USB port or restart your computer.
2. You dialed the potentiometer to the counterclockwise end. The voltage won't be stable.
I saw the error message about bootloader. You don't need to burn bootloader.
"Programmer is not responding" message could happen if the USB serial is disabled, or bad connection, or the serial port is not selected.
On the bottom line of serial monitor, you need to change the "newline" to "no line ending" in the drop-down menu. The parser in the code only accepts that format.
