Eric's Sainsmart 4WD Arduino Robot Code

Here is the current code, information and files for my Sainsmart 4WD robot build. The code is not optimized whatsoever but functions well enough at this point. So many people have asked for the code due to troubles- I decided to post it here.

You will need to modify the code to suit your setup and connections but this should provide a baseline for anyone struggling with their robot.

Good luck in your build. If this helped you please consider leaving a comment or thumbs up on my YouTube videos. There are several covering much of this robot build. For future updates please consider subscribing.

I ask 2 things of anyone who uses this:

• Give credit when possible to those who help you
• Improve and share code to better the experience for everyone

Cheers!

Note:
If you are here due to a high level of frustration with the programming, hardware and/or components- fear not. You are not alone. Check out the below vid (no link so as to not say bad things about anyone's products). I just about went crazy when I first built this thing- It DOES get easier. Hence me sharing the code ;)
