What is ADC in Arduino Uno?

In this tutorial we are introducing concept of ADC (Analog to Digital Conversion) in ARDUINO UNO. The Arduino Uno ADC is of 10 bit resolution (so the integer values from (0-(2^10) 1023)). This means that it will map input voltages between 0 and 5 volts into integer values between 0 and 1023.

What does ADC stand for in Arduino?

Analog-to-Digital Converter (ADC) A circuit that converts an analog voltage into a digital number representing that voltage. This circuit is built-in to the microcontroller, and is connected to the analog input pins of the Arduino board.

What are the types of ADC?

There are really five major types of ADCs in use today:

  • Successive Approximation (SAR) ADC.
  • Delta-sigma (ΔΣ) ADC.
  • Dual Slope ADC.
  • Pipelined ADC.
  • Flash ADC.

What is PWM in Arduino?

Pulse Width Modulation, or PWM, is a technique for getting analog results with digital means. Digital control is used to create a square wave, a signal switched between on and off. In other words, with Arduino’s PWM frequency at about 500Hz, the green lines would measure 2 milliseconds each.

What are the uses of Arduino?

Arduino is just a microcontroller board. Similar devices are used for everything from industrial process control, to controlling elevators, flying planes, and in alarm systems. However, arduino is not considered an industry quality device.

Is Arduino analog or digital?

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).

What is EEPROM in Arduino?

EEPROM on Arduino. EEPROM stands for Electrically Erasable Programmable Read-Only Memory. The microcontrollers used on most of the Arduino boards have either 512, 1024 or 4096 bytes of EEPROM memory built into the chip. This memory is non-volatile, which means that the data doesn’t get erased when the board loses power.

What is analog pin in Arduino?

Analog pins are general analog input pins, through which analog signal (Max range of 24v) can be feed to the arduino, for further analysis or value reading. PWM pins uses the concept of Pulse Width Modulation.
