The ATmega328 is a single-chip microcontroller created by Atmel in the megaAVR family.
Also know, what is the voltage output of Arduino pins?
If the pin has been configured as an OUTPUT with pinMode() , its voltage will be set to the corresponding value: 5V (or 3.3V on 3.3V boards) for HIGH , 0V (ground) for LOW . If the pin is configured as an INPUT , digitalWrite() will enable ( HIGH ) or disable ( LOW ) the internal pullup on the input pin.
How much current does Arduino Uno supply?
When arduino is powered by USB, the USB interface limits the current to maximum of 500ma for 5v rail, for 3.3v it is 200ma. When it is powered by external source 3.3v regulator and 5v regulators limit the current. Maximum current from 3.3v is 200ma and 5v is 1A.
What are the features of Arduino?
Features of the Arduino UNO:
Operating Voltage: 5V.
Input Voltage (recommended): 7-12V.
Input Voltage (limits): 6-20V.
Digital I/O Pins: 14 (of which 6 provide PWM output)
Analog Input Pins: 6.
DC Current per I/O Pin: 40 mA.
DC Current for 3.3V Pin: 50 mA.
What is P in atmega328p?
The “P” after the hyphen “-” means a Plastic DIL (Dual In Line) package so an ATmega328P-PU is a “picoPower”, “Plastci DIL” device and an ATmega328-PU is a standard power “Plastic DIL” device.
What is the AVR on Arduino?
The Arduino environment is based on Atmel Atmega microcontrollers. The AVR language is a “C” environment for programming Atmel chips. This page is an attempt to document the most useful AVR functions and code snippets.
What is Atmega 32?
ATmega32 is an 8-bit high performance microcontroller of Atmel’s Mega AVR family. Atmega32 is based on enhanced RISC (Reduced Instruction Set Computing) architecture with 131 powerful instructions. Most of the instructions execute in one machine cycle.
What is atmega2560?
The Arduino 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.
What is the ICSP header on Arduino?
This is referred to as in-circuit serial programming (ICSP) Most Arduino and Arduino compatible boards will have a 2×3 pin ICSP header on them. Some may even have more than one depending on how many ICs live on the PCB. It breaks out three of the SPI pins (MISO, MOSI, SCK), and power, ground, and reset.
What is a microcontroller and what does it do?
A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips.
What is the use of flash memory in Arduino?
Flash memory (program space), is where the Arduino sketch is stored. SRAM (static random access memory) is where the sketch creates and manipulates variables when it runs. EEPROM is memory space that programmers can use to store long-term information.
What is the abbreviation for AVR?
Short answers: — Sometimes Atmel says it means nothing in particular. — Sometimes Atmel has said it means “AdVanced Risc” or “Advanced Virtual Risc” — AVR = “Alf (Egil Bogen) and Vegard (Wollan) ‘s Risc processor”
What does AVR stand for on ECG?
aVR means augmented Vector Right; the positive electrode is on the right shoulder. aVL means augmented Vector Left; the positive electrode is on the left shoulder. aVF means augmented Vector Foot; the positive electrode is on the foot.
What does AVR stand for on a TV?
Modern home entertainment devices provide myriad ways of interconnecting your home system. The use of an audio/video receiver (AVR), for instance, can maximize your TV watching experience by outputting your TV’s audio through high-quality stereo speakers.
What is better for sound optical or HDMI?
Both are better than analog (the red and white cables). Both cables can be had pretty cheap. The biggest difference is that HDMI can pass higher-resolution audio, including the formats found on Blu-ray: Dolby TrueHD and DTS HD Master Audio. These formats can’t get transmitted across optical.
What is HDMI CEC control?
Consumer Electronics Control (CEC) is a feature of HDMI designed to allow users to command and control devices connected through HDMI by using only one remote control. For example, by using the remote control of a television set to control a set-top box and/or DVD player.
What is the CEC?
The Council for Exceptional Children (CEC) is the world’s leader in the devel- opment of standards for special educa- tion teachers. Practicing special educators can use the CEC standards to help them maintain the knowledge and skills necessary to meet the needs of their students.
What is HDMI CEC and ARC?
CEC stands for “Consumer Electronics Control,” and it needs to be enabled in both the TV and AV receiver for ARC to function. The HDMI-CEC setting is likely located in the general settings menu, and it can go by a variety of names.
Is HDMI the same as Arc?
The basics. In theory, ARC is supposed to let you have one connection between your TV and whatever you use to create sound: a receiver or a sound bar . You send video to the TV with an HDMI cable, and that same HDMI cable sends audio from the TV back down the same cable.
Is my receiver arc compatible?
Note: Normally, not all HDMI connectors on a TV or AV receiver are ARC compatible. ARC is clearly printed near the HDMI connector when it supports ARC allowing you to determine if this HDMI connector is ARC compatible. You can also refer to your owner’s manual to determine if your device is ARC compatible.
Can you connect speakers directly to a TV?
With very rare exceptions, you cannot connect a TV directly to standard speakers. The RCA connection outputs send a two-channel stereo (content dependent) from the TV to the external audio system. In this case, you can use a stereo mini-jack to RCA adapter cable.
What is a HDMI pass through?
HDMI Pass-Through passes video and audio signals from a high definition (HD) source such as a Blu-ray player or a HD set top box to a home theatre system (HTS) via a HDMI cable.
