Study Notes
- Analog input pins (A0-A5) accept analog values.
- The analog values are converted into a numerical representation ranging from 0 to 1023 via an Analog to Digital Converter (ADC).
- The ATmega328 chip is an 8-bit microcontroller.
- It processes the programmed sketch.
- The built-in LED is controlled through pin 13, where it is connected.
- The crystal oscillator has a frequency of 16MHz.
- The DC Jack is for connecting a power source like an AC-to-DC adapter or battery.
- The DC Jack input values should be between 6-20V, but 7-12V is recommended.
- Digital I/O pins (0-13) serve as both input and output pins.
- Six of the Digital I/O pins (3, 5, 6, 9, 10, and 11) provide PWM (Pulse Width Modulated) output using the analogWrite() function.
- Pins 0 (RX) and 1 (TX) are used for transmitting and receiving serial data.
- The ICSP Header provides pins for "In-Circuit Serial Programming".
- In-Circuit Serial Programming" is an alternative programming method.
- The ON indicator is an LED that illuminates when the board is connected to a power source.
- Power Pins supply a circuit with voltages VIN (from DC Jack), 3.3V, and 5V.
- The Reset Button restarts the sketch programmed on the board.
- The USB port connects the board to a PC for uploading sketches.
- The USB port can also supply voltage to the board.
- The USB port facilitates serial communication via the serial monitor in the Arduino software.
