How do I use GPIO pins in Arduino?
Arduino (ATmega) digital pins can be configured as output to drive output devices. We have to configure these pins to use as output. To configure these pins, pinMode () function is used which set direction of pin as input or output. This function is used to configure GPIO pin as input or output.
What is Arduino USB cable?
USB cable type A/B. Use it to connect Arduino Uno, Arduino Mega 2560, Arduino 101 or any board with the USB female A port of your computer. USB cable type A/B Standard USB 2.0 cable.
What are the pins on an Arduino GPIO?
Each pin plug can connect to one pin on your Arduino. For example, one wire could be connected to pin 13 (which will be used in this tutorial) and one other wire could be connected to the ground pin to power a tiny LED. Why the emphasis on a tiny LED?
How to connect an Arduino to a Raspberry Pi?
The simplest way to achieve this end is as follows. connect the Arduino and Pi grounds (i.e. connect a wire between an Arduino ground pin and a Pi ground pin). Connect an Arduino GPIO to a Pi GPIO. This is not as straightforward as connecting a wire as the Arduino GPIO are 5V and the Pi GPIO are 3V3.
What kind of pinout does the Arduino Uno use?
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. The versatility of the pinout provides many different options such as driving motors, LEDs, reading sensors and more.
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.
