I'm seeing about 3 times too many. > Really? I was not aware that the number of wires matters. I will check how I can reduce the number of wires on my breadboard. Anyway, I was maybe lucky but I have just successfully done a circuit using a lot of useless wires here: http://yugiohjcj.free.fr/elec-vusb-led-1.jpg http://yugiohjcj.free.fr/elec-vusb-led-2.jpg It is an USB connected breadboard that is controlled by a program on the computer [1, 2]. I can switch on or switch off the LED. So it works here with this project but it does not work with the USBasp project?
