ARDUINO UNO:
Arduino Uno is a microcontroller board based on the ATmega328P.
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button.
It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.https://sketchfab.com/3d-models/arduino-uno-943bae9bb86842408fc718b6e4c92ddb
