Good day everyone. I am trying to make a robot for fun. However, since I am still in college, I am poor. What I have in mind is controlling my robot through my computer. Therobot will follow basic instructions like forward, backward, right and left. I will send instructions through my computer by using a program that I will write (maybe C#). Since I don't want any wires connecting my robot and my computer, I need those two to communicate wirelessly. One of my concepts is using Bluetooth. But I don't know much about Bluetooth, and that is why I am posting this thread today. Does anyone know where I can buy some kind of Bluetooth devices that I can connect my computer to my robot? As I mention before, I am poor, so I am looking for something cheap. It will be even better if it is simple and easy to use. Or maybe i should look into something else than Bluetooth?
