How many analog and digital pins are in Arduino?
Arduino Uno is based on the ATmega328 by Atmel. The Arduino Uno pinout consists of 14 digital pins, 6 analog inputs, a power jack, USB connection and ICSP header. The versatility of the pinout provides many different options such as driving motors, LEDs, reading sensors and more.
What kind of inputs does Arduino Mega 2560 have?
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). It has 54 digital input/output pins (of which 14 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.
How many analog inputs do you need for Arduino Mini?
Such as the Arduino Mini with 8 analog inputs, the Arduino Due with 12 analog inputs (b), (a) the Arduino Mega with 16 analog inputs (b), the Teensy 3.0 with 14 analog inputs (c), etc. Add one or more external ADCs, and connect it to digital pins of your CPU.
What are the pins on a Mega 2560 microcontroller?
The 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.
Is there a way to have more than 14 output pins on Arduino?
Driving a MAX7219 requires only 3 output pins on Arduino. Also, you can find a few Arduino libraries for it. You can also chain several of them if you need to power more than 64 LEDs. I have used it successfully for multiple 7-segment LED displays. Downside: it is expensive (about $10). You can use Charlieplexing.
Which analog pins are used in Arduino Mega board?
Arduino – ArduinoBoardMega2560. The MEGA 2560 is designed for more complex projects. With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch it is the recommended board for 3D printers and robotics projects.

What pins support interrupts on the Arduino Mega 2560?
The Mega 2560 is capable of 6 external interrupts, which are 0-5 on pins 2, 3, 21, 20, 19, 18 respectively.
What is attachInterrupt () used for?
The first parameter to attachInterrupt() is an interrupt number. Normally you should use digitalPinToInterrupt(pin) to translate the actual digital pin to the specific interrupt number….Description.
| Board | Digital Pins Usable For Interrupts |
|---|---|
| Uno WiFi Rev.2, Nano Every | all digital pins |
Which pins are interrupt pins on Arduino Mega?
The Arduino Mega has six hardware interrupts including the additional interrupts (“interrupt2” through “interrupt5”) on pins 21, 20, 19, and 18. You can define a routine using a special function called as “Interrupt Service Routine” (usually known as ISR).
