Just built a Boarduino. I managed to place the C5 capacitor in the D2 position so had to unsolder that but apart from that mistake the power up test half way through went fine and the rest of the build went smoothly.
But it's not working
When I apply 9v power I get the green LED lit but the red LED blinks at approx 2sec intervals. Holding the reset button stops the red LED blinking.
When I attempt to upload the Blink sketch (I'm using the FTDI USB cable) I get the following error:avrdude: stk500_recv(): programmer is not responding
I've double checked all the soldered joints and all look sound. I wondered if the flashing red LED might indicate an obvious issue? Or have I fried the capacitor when I unsoldered it? Or maybe I have a faulty FTDI cable although given the red LED blinking on 9v power I don't think that's an issue.
