Three of us made a little Arduino project: Noah Marko Mesić, Tin Plavec, Tea Teskera. It's a remotely controlled car (a toy, not a real one). The car has an ultra sonic sensor so it will stop just before collision. We made the project as part of ICM workshop Summer Of Code 2018. At the end of the workshop, organizers proclaimed our project to be the best one on the workshop.
