This document describes a DIY UNO Play Breadboard that uses an ATmega328p microcontroller. It includes an FT232 breakout board to program the ATmega328p via USB without an onboard USB interface. The breadboard has 14 digital I/O pins, 6 analog inputs, and 6 PWM outputs. An example Arduino code is provided to blink 4 LEDs connected to different digital pins. The breadboard allows prototyping with the common ATmega328p in a similar way to an Arduino UNO board.

OVERVIEW
ATMEGA 328P PLAY BREADBOARD
Atmega 328 is one of the most commonly used Micro controllers with open source platform
amongst many hobbyist and industrial communities. The simplicity and the low power of
Atmega 328 helps design many prototype boards which could be used in numerous applications.
The UNO Play Breadboard also includes 6 analog inputs, 14 digital I/O pins (6 amongst these
could be used as PWM outputs), a crystal oscillator with 16MHz frequency, a 5 pin female
connector to connect FT232 plugin.This board does not have an inbuilt USB to directly load the
program from the computer. As we all know, once the program has been dumped into the board,
the part of the USB connectors become useless. So to load the program we have given common
interface through FT232 breakthrough board where we can connect to a computer and load the
codes into the UNO Play Breadboard ATMEGA328P
It’s a common high speed IC used to convert USB to serial converter. It’s quite commonly used
to connect a microcontroller TTL data to any USB interface host to establish a bridge for
communications between USB to serial devices. This particular breakthrough board can be used
to program RDL UNO ATMEGA 328P and use directly in to your own circuits. Also this
breakthrough board can also act as a bridge between Xbee and its Xbee utility software to
configure various Xbee’s.
