Arduino Audio Input: 8 Steps (with Pictures)
The Arduino has an ADC (Analog to Digital Converter) which is connected to various input pins on the board. In the case of the Uno they are labelled A0 to A5.
Opinions on continuously polling ADC for Arduino
Unlike timer interrupts, external interrupts are triggered by external events. For example, when a button is pushed or you receive a pulse from a rotary encoder. However, just like the timer interrupts, you don’t need to keep polling the GPIO pins for a change. The Arduino UNO has 2 external interrupt pins.

Internal (Software) interrupts of AVR Microcontroller (Atmega16). This tutorial with circuit C code explains the internal interrupts with the example of ADC interrupt. This …
Arduino Timer Interrupt ISR example - busylognet
/20/2012If you want anything even remotely related to speed, flush the Arduino bootloader down the toilet. 1) Set up ADC in free running mode. 2) Enable the ADC Noise Reduction sleep mode. 3) Start first conversion. 4) Enter sleep mode, in a while loop. 5) On wakeup from ADC interrupt, send data by USB or …
Arduino Timer Interrupts: 6 Steps (with Pictures)
Using Interrupts on Arduino. August 12, 2015 by Nash Reilly. Streamline your Arduino code with Interrupts - the simple way of reacting to real-time events! and not all pins can generate an interrupt! On the Arduino Uno, pins 2 and 3 are capable of generating interrupts, and they correspond to interrupt vectors 0 and 1, respectively.

Arduino Uno is a microcontroller board based on the ATmega328P (). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button.
