What is an arduino microcontroller?
An Arduino microcontroller is one that is based on the open source hardware/software programming platform named Arduino which are based on the Atmel microcontrollers. Open source means the circuitry and the software that is used in these Arduino microcontrollers are free to be used and modified by the people to their liking.
How many pins does a microcontroller have?
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, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started.
What is the use of Arduino?
Arduino designs and manufactures single-board microcontrollers and microcontroller kits for constructing a wide variety of digital devices that interact with objects and their environment to accomplish several tasks. Since Arduino is licensed under LGPL. It allows any manufacturer to build Arduino boards and develop its software.
What is the function of the Arduino serial monitor?
The Arduino Software (IDE) includes a serial monitor which allows simple textual data to be sent to and from the board. The RX and TX LEDs on the board will flash when data is being transmitted via the USB connection to the computer (but not for serial communication on pins 0 and 1).
What are the specs of an ATmega32u4 microcontroller?
Tech specs Microcontroller ATmega32U4 Analog Input Channels 12 DC Current per I/O Pin 20 mA DC Current for 3.3V Pin 50 mA Flash Memory 32 KB (ATmega32U4) of which 4 KB used by
What is the maximum Ma that a microcontroller can provide?
Each pin can provide or receive 20 mA as recommended operating condition and has an internal pull-up resistor (disconnected by default) of 20-50 k ohm. A maximum of 40mA is the value that must not be exceeded to avoid permanent damage to the microcontroller.
