Arduino Uno R3

Arduino UNO R3 is a development board based on the ATmega328 microcontroller. It has 14 digital input / output pins (6 of which can be used as PWM outputs), 6 analog inputs, a 16 MHz oscillator crystal, a USB connection, a power jack, ICSP, and a reset button. It contains everything you need to program the microcontroller, just connect it to a computer with a USB cable, you can connect it to an AC-DC adapter or a battery to start using it.
