- 5 Digital I/O pins
- 4 Analog pins
- Integrated LED on pin 13
- Integrated ON/OFF switch
- Built-in energy supply socket (JST connector) for a 3.7V LiPo battery and charging you circuit ( no extra battery pack charger required)
- Simplified layout with less pins, providing more space for sewing or less complex projects
Central to the Simple board could be the ATmega328 — the major black colored square in the center of the board.
Here is the microprocessor, the “brains regarding the procedure.” This is exactly what shops and executes your Arduino design. Surrounding the ATmega328 are really a few passive components that are supporting nothing all that important for you.
Towards the right regarding the ATmega328 (though it will be difficult to see unless it really is lit) is a little little Light-emitting Diode. This might be categorized as the utmost component that is important the Arduino. The Light-emitting Diode is linked with Arduino pin 13, and will be utilized for all you blinking needs. During the left that is top there’s a momentary push switch, utilized to reset the ATmega328. Continue reading
