The Arduino UNO is an open-source microcontroller board based on the Microchip ATmega328P microcontroller. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, 16 MHz quartz crystal, USB connection, power jack, and ICSP header with 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. With Arduino Software (IDE), the UNO is the best board to get started with electronics and coding. I’m looking forward to coding and adding modules to the expanding UNO as a proof-of-concept testbed for new ideas and applications. Looks like more visits to the local RadioShack are in the future.
