What kind of pinout does the Arduino Uno use?
In this post, we’ll be taking a closer look at the Arduino hardware, and more specifically, the Arduino Uno pinout. Arduino Uno is based on the ATmega328 by Atmel. The Arduino Uno pinout consists of 14 digital pins, 6 analog inputs, a power jack, USB connection and ICSP header.
Is there a way to program Arduino Uno?
You can program Arduino UNO using ISCP or use the ISCP of Arduino UNO to program other Arduino Boards. Digital IO Pins 2 and 3 can be configured as External Interrupts Pins INT0 and INT1 respectively. Use attachInterrupt () function to configure the Interrupt for rising edge, falling edge or level change on the pin.
What kind of voltage do you need for Arduino Uno?
Above 12 volts, the regulators might overheat, and below 7 volts, might not suffice. VIN Pin – This pin is used to power the Arduino Uno board using an external power source. The voltage should be within the range mentioned above. USB cable – when connected to the computer, provides 5 volts at 500mA.
What do you do with the ioref pin on Arduino Uno?
Using the IOREF pin, you can set the reference voltage for Microcontroller operations. To reset the microcontroller, you can use the on-board RESET button. Although you can program the Arduino UNO using the USB cable, there is a provision to program the MCU using the In-Circuit Serial Programming (ICSP) interface.
What kind of pin do I need to power my Arduino?
Powering Your Arduino Via the 5V Pin. If you have an external regulated power source that outputs 5 volts, then you can connect it directly to the 5V pin of the Arduino board. The input on the 5V pin should not exceed 5.5V volts!
What are the interrupt pins on an Arduino?
Arduino has two forms of interrupt: There are two external interrupt pins on the ATmega168/328 called INT0 and INT1. both INT0 and INT1 are mapped to pins 2 and 3. In contrast, Pin Change interrupts can be activated on any of the pins.
How does the VIN pin on an Arduino work?
Connect the positive output of your 7 to 12 volt power supply to the Vin pin of your Arduino, and the negative to the GND pin. The Vin pin goes to the input of the onboard 5V regulator. The power source you connect to the Vin pin has to be 7 to 12 volts for the regulator to work reliably.
