What can you do with Arduino Leonardo?
Single processor for sketches and USB communication The Leonardo, Leonardo ETH and Micro differ from other Arduino boards in that they use a single microcontroller to both run your sketches and for USB communication with the computer.
How does Arduino convert analog to digital?
The microcontroller of the board has a circuit inside called an analog-to-digital converter or ADC that reads this changing voltage and converts it to a number between 0 and 1023. When the shaft is turned all the way in one direction, there are 0 volts going to the pin, and the input value is 0.
What is the resolution of analog output of Arduino?
The Arduino board contains a 6 channel (8 channels on the Mini and Nano, 16 on the Mega), 10-bit analog to digital converter. This means that it will map input voltages between 0 and 5 volts into integer values between 0 and 1023. This yields a resolution between readings of: 5 volts / 1024 units or, .
How does a DAC work on an Arduino?
If your not sure what they do then very simply they convert a digital value (i.e. a number) to a corresponding voltage on an output pin.. This is basically the range of numbers that you can send to your DAC and they start at 0 to a maximum value.
What kind of inputs does the Arduino Leonardo have?
The Arduino Leonardo is a microcontroller board based on the ATmega32u4 ( datasheet ). 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.
How to use a circuit on an Arduino?
To use the circuit you only have to connect the input on a digital pin with PWM, and use the analogWrite function on your sketch. The code shown below will output a square wave of 50% duty cycle on pin 5 and the DAC will output around 2.5V. The image shows the output of the Arduino and the filtered output of the DAC.
Can a Leonardo microcontroller communicate with a computer?
The Leonardo has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega32U4 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX).
