Astro-Tracker - Astroduino

thingiverse

A nice Arduino project! It looks like you've written a star tracker program for the Astroduino, which is a modified Arduino board designed specifically for astronomy projects. Here are some observations and suggestions: 1. **Code organization**: Your code is well-organized, with clear sections for setup, loop, and functions. However, some of the variables (e.g., `adc_key_in`, `key`) could be declared at the top of the file to make it easier to understand their purpose. 2. **Variable names**: Some variable names are not very descriptive (e.g., `k` in the `get_key` function). Consider using more meaningful names to improve code readability. 3. **Magic numbers**: You have several magic numbers scattered throughout the code (e.g., `1000000`, `16`, `2`, etc.). Consider defining constants for these values to make the code easier to understand and maintain. 4. **Comments**: While you have some comments explaining what certain sections of code do, there are areas where more comments would be helpful (e.g., the `motorrun` function). 5. **Code style**: Your code style is generally consistent with Arduino's coding conventions. However, consider using a more consistent naming convention for variables and functions (e.g., camelCase vs. underscore notation). Here are some minor suggestions: * In the `setup` function, you can remove the `lcd.clear()` call after initializing the LCD display. * In the `loop` function, you can use a `switch` statement instead of multiple `if` statements to handle different key presses. * Consider adding more comments to explain the purpose of each function and how they interact with each other. Overall, your code is well-organized and easy to follow. With some minor improvements, it will be even more maintainable and understandable for future developers working on this project!
