# Me and My Arduino ## Introduction The more I learn about MQTT, the more intrigued I become. I recently purchased an Arduino Starter Kit containing an Arduino Uno R3, a book with 15 projects, and a variety of sensors, resistors, LEDs and more. I'm anxious to develop an MQTT project and thought it best to start with minimal investment at this time. A quick search of the Library Manager suggests several MQTT libraries are available: ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661735990800/la6Sw8D3f.png align="center") ## Arduino IDE Visit the [Arduino Software page](https://www.arduino.cc/en/software#experimental-software) to download the stable (1.8.19), latest release candidate (2.0.0-rc9.3) or nightly builds. I highly recommend downloading the [Arduino IDE 2.0.0 (rc9.3)](https://www.arduino.cc/en/software#experimental-software) directly from the Arduino.cc website. As part of the installation process, you will be prompted to provide permission to download libraries to your machine as well, and there are many of them. Version 2.0.0 is more intuitive and user friendly. ## Getting Started - arduino.cc/starterkit [Arduino Software - Downloads](https://www.arduino.cc/en/software) ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661729307194/GIkfdLquA.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661729383541/G3l2rj4Xm.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661729409988/T283zV7ec.png align="center") ## Windows Security ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661729534025/wdBYP3J8h.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661729562414/Yfu7TUbxK.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661729587110/D0rAvhsWZ.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661729661186/x7MtBVe4x.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661731084175/AnELrJEto.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661731102513/gtB40PyCU.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661724274810/EbWMLxNUT.png align="center") [Windows in Store App](https://apps.microsoft.com/store/detail/arduino-ide/9NBLGGH4RSD8?hl=en-ca&gl=CA) ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661724308215/aiYTFZjAf.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661723491720/EE9w5UCSp.png align="center" ## WiFi101/WiFiNINA Firmware/Certificates Updater ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661732149663/cbxqKmcVG.png align="center") ## Troubleshooting I plugged in my Arduino using the USB port and attempted to connect only to receive this error: "Board at null is not available." ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661733265116/rAZcdpoG8.png align="center") Device Manager Windows > Control Panel > Device Manager ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661733807384/JuWfNRqZ0.png align="center") Clicking on the Arduino Uno (COM3) ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661733748004/7m589lHDq.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661733868371/p6njGG6Zr.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661733889978/KeQFwNggn.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661733923004/i8TAOtRHk.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661733960187/gvF99gCO9.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661733976001/gug9QN_0u.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661734119996/_9sLp5x0a.png align="center") # ERRORS! ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661734609791/DK6cjBzgA.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661734756246/6_7dDSptV.png align="center") ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1661735429774/IufoYegZ2.png align="center") Right Click and Update the Drivers.
