Arduino leonardo analog input

The Leonardo has 12 analog inputs, labeled A0 through A11, all of which can also be used as digital i/o. Pins A0-A5 appear in the same locations as on the Uno; inputs A6-A11 are on digital i/o pins 4, 6, 8, 9, 10, and 12 respectively. Each analog input provide 10 bits of resolution (i.e. 1024 different values) Everything works great if I use only digital pins. I wanted to put two controllers on one Arduino Micro. I need 16 inputs and ground. The Micro has 20 inputs (using analog). It should work. But if I use just 1 analog pin, this does not work. I am testing it with just one controller. If I use pins 2-9, it works fine

Arduino Leonardo Pinout - ElectroSchematics

  1. The Arduino team is now shipping their latest creation - the Leonardo. It is the first Arduino to use Atmel's ATmegaXU4 series chip with built-in USB. This change is big and it has big benefits. In addition to the built-in USB, it offers more digital and analog pins. This step by step guide gives you the details you need to know to start.
  2. While looking into arduino/Arduino#1741 (and totally misunderstanding that issue at first), I found some weirdness with the A6 to A11 constants in leonardo's pins_arduino.h.. The documentation says:. Analog Inputs: A0-A5, A6 - A11 (on digital pins 4, 6, 8, 9, 10, and 12) However, the values of the A6..A11 constants are not those, 4, 6, etc. but different pin numbers starting at 24
  3. Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and the operating voltage(5V or 3.3V) into integer values between 0 and 1023. On an Arduino UNO, for example, this yields a resolution between readings of: 5 volts / 1024 units or, 0.0049 volts (4.9 mV) per unit
  4. Arduino pinMode on Analog Inputs. All Arduino boards contain analog and digital pins. The Arduino functions have different calls depending on the pin type. For example, when calling analogRead(), an analog input pin is automatically changed from a digital input (or output) into an analog input
  5. Arduino Tip : Turn your Analog pins into Digital I/O. Posted Apr 5 2012 by waihung in Arduino with 13 Comments. Recently I've just found out that I can actually turn my Analog input pins into Digital Inputs or Outputs. It's really simple. Usually for the digital pins, we write instructions such as digitalWrite(13, HIGH)
  6. The Arduino Uno or any other Arduino board that uses Atmega328 as the Microcontroller has ADC resolution of 10 bits. Hence the values on each analog channel can vary from 0 to 1023. Now connecting the VRx to A0 and VRy to A1 analog inputs respectively should show values as shown in the image below

The Arduino can input and output analog signals as well as digital signals. An analog signal is one that can take on any number of values, unlike a digital signal which has only two values: HIGH and LOW. To measure the value of analog signals, the Arduino has a built-in analog-to-digital converter (ADC) Arduino Leonardo Introduction: The Arduino Leonardo is a microcontroller board based on the ATmega32u4 ().It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button Arduino Leonardo.
