UNO-R3 development board improved version of electronic microcontroller kit expert version to send row needle enhanced version of the version

Introduction

Open the original design of the circuit diagram, the development of software interface free download, can also be modified according to the needs of their own, download program is simple and convenient. Can simply use the sensor, a variety of electronic components connected (such as: LED lights, buzzers, buttons, photoresistors, etc.), to make a variety of interesting works.
The use of high-speed micro-processing controller (ATMEGA328), the development of the interface and environment are very simple, easy to understand, very suitable for beginners to learn.
