DFRduino Beginner Kit For Arduino (SKU:DFR0100)

Introduction

Welcome to the electronic interaction world! DFRobot proudly presents the Arduino beginner kit for those who are interested in learning about Arduino. Starting from basic LED control to more advanced IR remote control, this kit will guide you through the world of microcontrollers and physical computing.

A DFRduino UNO R3 (Compatible with Arduino Uno), the most stable and commonly used Arduino processor, together with DFRobot's best selling prototype shield are included in this kit.


Getting Started with Arduino

Introduction: What Arduino is and why you'd want to use it.

Installation: Step-by-step instructions for setting up the Arduino software and connecting it to an Arduino Uno.

Windows Mac OS X
Environment: Description of the Arduino development environment and how to change the default language.
Libraries: Using and installing Arduino libraries.

FAQ

Q. I have to say that I am loving the kit. I just wanted to let you know of an issue that I have encountered. In projects 11 and 12 of the kit, it requires the use of the 3 potentiometers. The problem is that the terminals of the potentiometers do not fit across into the sockets on the Prototyping Shield nor the provided breadboard. They are to wide.


A. Hello, your feedback is very precious to us. Just as you said, the potentiometer couldn't be inserted to the hole easily, but with some strength to push it downward, it could be done. I've attached a picture about it. Btw, we will consider to upgrade it.
