This sketch uses "bit banged" SPI for programming the target chip, which is why it uses pins D4, D5, D6, D7 instead of the hardware SPI pins. See the source code (and above forum post) for details ...

They will likely come into contact with the top of Arduino’s USB connector. Sadly, I got such a hampered multifunction shield, but a slice of thin film helped me to clear that issue. First test: LED ...

If the board doesn’t hang but returns to the Arduino blink sketch (Led on pin 13 blinks every now and then), a straightforward fix will be to flash the board with the Arduino bootloader, as the one on ...

As for the pins, the UNO features 14 digital pins for both input and output use, ... Probably the most complex part of working with Arduino is creating the sketch, a.k.a. writing the code.

By default, all Arduino pins are inputs. On the other hand, power pins are meant for moving electricity around the board. 5V and 3.3V always emit as much voltage as their name says. ... Upload your ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...
