Then, chances are you already know what an Arduino is ... The Nano features an ATmega328, while the Uno sports an ATmega328P. As they're both 8-bit AVR RISC-based microcontrollers, they share ...

So it’s little wonder that someone like [Aaron Christophel] would try to repurpose those sub-$3 AVR programmers ... you have essentially an Arduino with limited pinout and two onboard LEDs ...

“When it comes to hardware compatibility, pinout, voltage and form factor are unchanged from UNO ... the AVR architecture used in R3 will need to be ported. To help in the transition, Arduino ...

Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive ...

The pinout diagrams are simple, but they're easy to read, and especially helpful for beginners. You can print them out full size so you can set your Arduino Uno, ATMega, or ATTiny right on top for ...

Apart from understanding the Arduino's code ... similar to the iconic Uno in a lot of ways. For instance, it's based on the same microcontroller, uses almost identical pinout configuration ...
