# Arduino ## Arduino Failure Occasional Arduino failures have been reported on eChook V1 boards, and we suspect they may be more common than currently reported. A key indicator is the Arduino chip becoming hot to the touch. If you see this, please email with supporting details, including your eChook PCB version, Arduino model, purchase date, duration of use, and the circumstances under which the failure occurred. If the Arduino is getting hot to the touch (too hot to comfortably hold a finger against) a new Arduino is required. ## Arduino Compiling and Uploading While we have tested the code we provide, there are many factors that can stop it compiling and uploading on different computers. The error log given in the Arduino IDE is not much help by default. Go into preferences and [enable verbose logging](/programming-the-arduino/programming-the-arduino.md#compilation-errors) to get more detailed logs. The most common issues can be addressed with the following checks: * Install the latest [Arduino IDE](https://www.arduino.cc/en/Main/Software). * Install the [CH340 Drivers](/programming-the-arduino/arduino-ch340-drivers.md). * Select the [correct board and COM port](/programming-the-arduino.md). * Install the [Bounce2 Library](/programming-the-arduino/download-the-echook-arduino-code.md). * Re-download the [eChook code](https://github.com/eChook/eChook-Arduino-Nano) to ensure no local changes have been made. If it still fails, take a copy of the errors and post it on the [forum](https://echook.boards.net), or contact us on webchat, and we'll help you decipher it. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.echook.uk/troubleshooting/arduino.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
