I recently made my custom Arduino with the help of this tutorial:http://itp.nyu.edu/physcomp/Tutorials/ArduinoBreadboard
I wired everything up like in the tutorial, except the Sparkfun USB to Serial converter, I use the Arduino USB to Serial Converter Light.
Now the problem is that when I try to upload the example Blink sketch, the Arduino IDE 1.0 gives this error:
avrdude: stk500_getsync(): not in sync: resp=0x00
What could be the problem?
I already checked this forum and the internet for solutions, but none of them work.
I've installed this driver: http://arduino.cc/en/uploads/Main/Arduino_USBSerial.zip
If I look in the device manager, the COM is fine and don't needs an update.
In the Arduino IDE, I've selected COM 7(it's the right COM) and selected Arduino Uno as my board.
I'm using the ATmega328 chip with the Uno Optiboot(it was already when I bought it).
Maybe the problem is that I don't have the Reset pin connected on the USB2Serial board? Only the TX, RX, 5V and GND are connected.
I've also seen that the led on my custom Arduino doesn't flash if I reset it.
And also, the TX and RX leds flash when uploading a sketch.
Things I've tried:
- Upload the sketch and press Reset with different timing
- Selecting different boards in the IDE
- Press reset before uploading the sketch
- Replacing the ATmega328 with another(also with optiboot)
