I bought and constructed the Gertboard kit. The initial led tests work fine.
I set up the atmega stuff according to https://projects.drogon.net/raspberry-p ... duino-ide/
I started the arduino ide, set the board and chip, loaded the blink program and uploaded it. It says all is ok.
With a meter, I can see the voltage on PB5 jumping up to about 0.5v every second. I connect the PB5 pin to BUF1 ping on the board, expecting to see D1 flash, but nothing happens. Could someone point me to what I might be doing wrong please?
