Hi! My name is John and I go to Vina Danks Middle School. For the last 3 weeks, for one day a week I have been working on a lego project. On these days I have made a wheelchair that is controlled by a joystick. With this wheelchair I can program it to go where I can control it with a joystick made out of legos. This makes you feel like you are driving a car or playing a video game.
The biggest problem that I had was getting it programmed to where I could drive the wheelchair with the joystick. It was hard to get the commands correct so it would go forward when I told it to and backwards also. Most of the time it would turn when I told it to go forward.
