So awhile ago, I did a blog post about me getting a smart robot car, but after I finished assembling it, some of the functions on the control app didn't work. Instead of moving forward or backward, it would turn the robot into obstacle avoidance mode. After a while of trying to figure it out I gave up on it, until about three days ago when the app for the smart robot car started popping these messages saying: "If you have the smart robot car v3.0 then download the mainboard program again from the Elegoo downloads page" The problem was that the message wasn't really that specific on what to download and where to find it. I went to Elegoo's download page, and I scrolled down the page until I found a program that was called "Smart Robot Car v3.0 Plus" I Downloaded that one, when it finished downloading I opened it to see where the "Mainboard program" was, but I couldn't find it. So asked my older Brother Nicholas for help because he has used an Arduino before and knew a lot about computer-related stuff. He looked a little but couldn't find it in the files of the one I just downloaded so he decided to look at the code that the robot car already had and tried to manually edit it. It took him about an hour or so when he said it would take a very long time to rewrite all of the code, so he had a look at the files I downloaded earlier and then he found it. He found it by searching the folder for it, the reason I couldn't find it earlier was that I didn't search the folder for it. Instead I opened each folder looking for it. So he uploaded the code into the robot car, and it started to work with every tool in the app. So now it is fixed and it's pretty fun to play with!
