HellO everyone
I'm new with arduino but I am eager to learn things about it so i consider it for my project. But my professor wants us to explore electronics more so she didn't want us to buy ready made boards and modules.. So i decided to make one of arduino compatible boards and i got this here (http://www.instructables.com/id/DIY-Arduino-or-The-DIY-Duino)
I have made the board successfully and now I am testing it using blink sketch.. I connected the board using usb to uart(serial ttl) prolific pl-2303 instead of an ftdi breakout board because it is not available in our place. I connected rxd and txd to the board as well as 5v and gnd then the power LED On. And when i upload the blink sketch ... i press reset button as binary sketch,etc.. The led on pin13 blinks once. After this an error appears

avrdude: stk500_getsync(): not in sync: resp=0x00

could you help me to solved this??

You made your own board? Where did you get the ATmega chip from? Does it have the Arduino bootloader on it?

On the Arduino sketch page, go into the Tools>Board and select 'Arduino Mega 2560 or Mega ADK'
