What are the pins that we Cannot use in the Arduino?
Digital Ground (light green) Digital Pins 2-13 (green) Digital Pins 0-1/Serial In/Out – TX/RX (dark green) – These pins cannot be used for digital i/o (digitalRead and digitalWrite) if you are also using serial communication (e.g. Serial.
How many IO pins does Arduino Mega have?
54
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
Does Arduino have GPIO pins?
While the main function of the analog pins for most Arduino users is to read analog sensors, the analog pins also have all the functionality of general purpose input/output (GPIO) pins (the same as digital pins 0 – 13).
What are the maximum pins for Arduino Mega?
Maximum Current for I/O Pins. 1 J0-J7 + A0-A7 + G2 < 200mA. 2 C0-C7 + G0-G1 + D0-D7 + L0-L7 < 200mA. 3 G3-G4 + B0-B7 + H0-B7 < 200mA. 4 E0-E7 + G5 < 100mA. 5 F0-F7 + K0-K7 < 100mA.
What kind of power does an Arduino Mega have?
The Arduino Mega has in total one 3.3V pin and four 5V pins, which are able to provide a current up to 50 mA. The VIN power pin can also serve as power supply for the microcontroller with a voltage range between 7V-12V.
Do you need voltage regulator for Arduino Mega?
The Arduino Mega can also be powered via the USB port. There is no need for a voltage regulator because the USB connection is already regulated by the USB output from your PC or laptop. The maximum current draw from the USB connection is therefore reduced to 500mA.
How can I Power my Arduino Mega microcontroller?
Like the Arduino Uno, you can power your Arduino Mega in three save ways because a voltage regulator provides a regulated and stable voltage for the ATmega2560 microprocessor: USB cable: The most popular and also the easiest way to power the microcontroller is via USB cable.
