Not exactly schematics, but [Duckman] has some Arduino pinout diagrams he made using ASCII-art. These could be useful when pasted into source code as comments, documenting the pinouts for your ...

Arduino pinout diagrams, schematic symbols, trace widths for current capacity, and even typical coding functions! The full image is 9,000 x 6,000 pixels and will print nicely at 30 by 20 inches ...

Just follow the schematic diagram to complete the construction ... Pin 15 on the IC is actually the pin for Digital Pin 9 (D9) on the Arduino. If you want to see the pinout for the ATmega328 IC, refer ...

In the case of Arduino, the ATmega chip on the board ... All microcontrollers (at least, those with datasheets) have a pinout schematic and pin description. For example, below is the pinout ...

Now that your rotary encoder hardware is up and running it’s time to tell your Arduino what to do with the encoder signals. There are the two basic ways to read a microcontroller’s digital input. With ...
